zStress corrosion cracking (SCC) refers to the cracking caused by the combined action of stress corrosion stress (mainly tensile stress) and corrosion of austenitic stainless steel Austenitic stainless steel is prone to stress corrosion in corrosive media containing chloride ions. When the Ni content reaches % - %, it is a long-term enterprise engaged in stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe. Welcome to consult. The stress corrosion tendency of austenitic stainless steel is very large. Continue to increase the Ni content to ~ %,stainless steel sheet and the stress corrosion tendency gradually decreases until it disappears.

It has excellent stress corrosion cracking resistance. Even duplex stainless steel with low alloy content has higher stress corrosion cracking resistance than austenitic stainless steel, especially in the environment containing chloride ions. Stress corrosion is a prominent problem that ordinary austenitic stainless steel is difficult to solve.

AfIts alloy composition (chromium, nickel, titanium, silicon, aluminum, etc.) and the internal structure of stainless steel coil plate are mainly composed of chromium. Chromium has high chemical stability, can form a passive film on the steel surface, isolate the metal from the outside, the corrosion resistance decreases.

No matter under dynamic load or static load,stainless steel sheet it has higher energy absorption capacity than austenitic stainless steel, which has obvious advantages and practical application value for structural parts to deal with sudden accidents such as collision and explosion. Compared with austenitic stainless steel, duplex stainless steel has the following disadvantages: its universality and versatility are not as good as austenitic stainless steel. For example, its service temperature must be below ℃.

Difference between L stainless steel pipe and stainless steel pipe: and L stainless steel are molybdenum containing stainless steel. The molybdenum content of L stainless steel is slightly higher than that of stainless steel. Due to the molybdenum in the steel, the overall performance of this steel is better than that of and stainless steel. Stainless steel has a wide range of applications under high temperature conditions when the concentration of is lower than % and higher than %. In addition, stainless steel also has good chloride corrosion performance, so it is usually used in marine environment. The large carbon content of L stainless steel is ., which can be used in applications where annealing cannot be carried out after welding and great corrosion resistance is required.

rAustenitic stainless steel. It contains more than % chromium, about % nickel and a small amount of molybdenum, titanium,stainless steel sheet stainless steel coil, stainless steel belt, stainless steel pipe, large quantity, strong and durable safe and reliable. The performance of the alloy is that the welding metal and heat deteriorated part still maintain the same corrosion resistance, but its welding procedure needs to be designed so that after welding, it can maintain a good phase balance and avoid the precipitation of harmful metal phase or non-metal phase. Welding can be carried out in the following equipment: GTAW (TIG); GMAW (MIG); SMAW (“stick” electrode); SAW; FCW; And paw stainless steel features: compared with L and L austenitic stainless steel, duplex stainless steel alloy has superior performance in spot corrosion and crack corrosion resistance. It has high corrosion resistance. Compared with austenite, it has lower coefficient of thermal expansion and higher thermal conductivity.

GHonest managementTi-a alloy with improved titanium and overall corrosion resistance has been used to manufacture u and Pu solution evaporation boilers and heat recovery evaporation boilers in Donghai reprocessing plant, Japan. In addition,tisco stainless steel sheet,taigang stainless steel sheet,stainless steel sheet,stainless steel coil,stainless steel strip,stainless steel tube-TISCO Stainless Steel Co.,Ltd because zirconium has stable corrosion resistance in the environment, zirconium is used in its continuous dissolution tank in the reprocessing plant in liusuo village, Aomori County, Japan. The U.S. Court ruled that the countervailing duty is not suitable for products from non market economy countries, which has just given Chinese steel pipe enterprises a little relief. The anti-dumping stick from the European Union has dealt a heavy blow to hundreds of domestic stainless steel pipe manufacturers.

dKAir pressure and water pressure test: conduct water pressure test for pressure resistant pipes one by one, and keep it for no less than seconds at the specified pressure value. The water pressure test of conventional supply is MPa. The air pressure test is p = .mpaa.

The difference between duplex stainless steel plate and ferritic stainless steel plate: the comprehensive mechanical properties are better than ferritic stainless steel, especially the plastic toughness, which is not as sensitive to brittleness as ferritic stainless steel.

Steel pipes also rust. I believe many friends will be surprised! I believe there are many people who dont know how to explain to customers! Next, lets popularize science!

Good reputationhAllowable depth of straight track: for hot rolled and hot extruded steel pipes with diameter less than or equal to mm, it shall not be greater than % of the nominal wall thickness, and the large depth shall not be greater than .mm; for cold drawn (rolled) steel pipes, it shall not be greater than the nominal wall thickness

HChloride ions exist in the service environment. Chloride ions exist widely, such as salt, sweat, sea water, sea breeze, soil floating rust splashed by iron foam and so on. Stainless steel corrodes rapidly in the presence of chloride ions, even more than ordinary low carbon steel. Therefore, there are requirements for the service environment of stainless steel, and it needs to be wiped frequently to remove dust and keep clean and dry. (this will give him a & ldquo; improper use & rdquo;) there is an example in the United States: an enterprise uses an oak container

Seamless stainless steel pipe, also known as stainless steel pipe, is made of steel ingot or solid pipe blank through perforation and then made by hot rolling, cold rolling or cold drawing. The specification of seamless steel pipe is expressed by outer diameter * wall thickness mm. With the implementation of Chinas reform and opening-up policy, the national economy has achieved rapid growth, and a large number of urban houses, public buildings and tourism facilities have been built, which puts forward new requirements for hot water supply and domestic water supply. In particular, people pay more and more attention to the problem of water quality, and the requirements are also increasing. Galvanized steel pipe, a common pipe, will gradually withdraw from the historical stage under the influence of relevant national policies because of its corrosiveness. Plastic pipe, composite pipe and copper pipe have become common pipes in the pipeline system. However, in many cases, stainless steel pipe has more advantages, especially the stainless steel pipe with wall thickness of only . ~ mm, which has the characteristics of safety, reliability sanitation, environmental protection, economy and applicability in high-quality drinking water system, hot water system and water supply system that puts safety and sanitation first. It has been proved by engineering practice at home and abroad that it is one of the new, energy-saving and environmental protection pipes with good comprehensive performance of water supply system. It is also a very competitive water supply pipe, which will play an incomparable role in improving water quality and peoples living standards.

yAt low temperature, coils, belts and tubes with quality assurance. The company specializes in selling, timely supply and high cost performance. It has become the first choice brand for many wire products. Welcome to buy! Ferritic stainless steel tubes have low temperature brittleness like carbon steel, while austenitic steel does not. Therefore, ferritic or martensitic stainless steel produces low temperature brittleness Temperature embrittlement, but austenitic stainless steel or nickel base alloy does not show low temperature embrittlement. Sus (Cr), SUS of ferritic stainless steel pipe (cr) and others show a sharp drop in impact value at low temperature. Therefore, high purification process can be considered. With the help of grade C and N, when the embrittlement temperature is improved in the range of - ℃ to - ℃ it is possible to use it in freezing related projects SUSL has applied suslx (cr Ti, Nb LC) and susl (cr Mo Ti, Nb LC) to the shell of refrigeration appliances. Ferritic stainless steel has body centered cubic structure. When the material properties become weak, sharp cracks will expand rapidly and cause brittle failure. Austenitic series stainless steel will not produce brittle failure because it is face centered cubic structure. Arctech has invested in stainless steel (cr-ni-lc) and SUSL (cr-ni-mo-lc) show that they still have superior impact characteristics at low temperature. However, pay attention to the precipitation of ferrite or martensite due to processing, and the tendency of embrittlement caused by carbide or & sigma; equal heterogeneous precipitation due to sensitization.

qPThe internal and external greasy dirt and sundries at the pipe end shall be completely removed to keep the pipe inside the pipe fittings clean.

It is generally suitable for the welding of thin plates below mm, with the characteristics of beautiful weld formation and small welding deformation.
