1HL polishing with appropriate particle size abrasive material to make the surface show continuous grinding lines.
hStainless steel pipe is safe， reliable， hygienic environmentally friendly， economical and applicable. The successful development of pipeline and new reliable， simple and convenient connection makes it have more irreplaceable advantages of other pipes. It will be used more and more in engineering， and the use will be more and more popular. It has a good prospect.
Hot rolled stainless steel tubes are generally produced on automatic tube rolling mills. After inspection and removal of surface defects，304 stainless steel plate the solid pipe blank is cut into the required length，Price of 0.2mm stainless steel plateThe industry benefits from policy support centered on the end face of the perforated end of the pipe blank， and then sent to the heating furnace for heating and perforated on the piercer. During perforation it rotates and advances continuously. Under the action of roll and plug， a cavity is gradually formed inside the pipe blank， which is called rough pipe. Then it is sent to the automatic pipe mill to continue rolling. After that， the wall thickness of the whole machine is adjusted， and the diameter is determined by the sizing machine to meet the specification requirements. It is advanced to produce hot rolled seamless steel pipe by continuous pipe mill.
PGarokan SPHCSPHC—& mdash; In the first place， s is the abbreviation of steel， P is the abbreviation of plate， h is the abbreviation of hot heat，304 stainless steel plate and C is the abbreviation of commercial. It generally represents hot-rolled steel plate and strip.
EhL stainless steel pipe is a kind of hollow long round steel， which is mainly used for industrial transmission pipelines and mechanical structural components such as petroleum， medical treatment， food， light industry， machinery and instruments， etc. In addition， when the bending and torsional strength are the same， so it is also widely used in all kinds of manufacturing mechanical parts and engineering structures.
D-outer diameter (mm) as stainless steel pipe for reprocessing device， in order to reduce carbon content by vigorously welding chromium carbon compounds at affected parts，304 stainless steel plate or silicon and phosphorus content in Nb steel. In addition， in order to improve the corrosion resistance of ULC steel，Price of 0.2mm stainless steel plateThe industry benefits from policy support the steel industry with phosphorus content below .% is manufactured. Through repeated % boiling corrosion tests for times， it is concluded that if the corrosion degree of solid solution treated material is less than .mm/a， ℃ & times; The sensitized material for h has excellent corrosivity when the corrosion degree is less than .mm/a.
No matter under dynamic load or static load， 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 ℃.
eThe recrystallization temperature changes with the shape variable. When the shape variable is % the recrystallization temperature drops to ℃， and the recrystallization annealing temperature of cold deformed austenitic stainless steel is ~ ℃. At ℃，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 it needs to be kept warm for h， fully burned at ℃， and then water-cooled.
XCompared with traditional steel， but also have good plasticity， toughness， formability and weldability. It is the first choice for car frame. Stainless steel with superior performance can create cars with light weight， strong resistance， high safety and long service life. Such frames can be recycled and reused. It can not only save costs， but also save resources. And some other auto parts are also made of stainless steel. Stainless steel has a great potential market in the whole automobile industry!
UFair priceAccording to different metallographic structure of stainless steel， it is divided into semi Ferritic and semi martensitic stainless steel pipe， martensitic stainless steel pipe， austenitic ferritic stainless steel pipe， etc.
hCThe linear expansion coefficient of austenitic stainless steel is lower than that of austenitic stainless steel， suitable for connection with carbon steel， and has important engineering significance such as the production of composite plate or lining.

LBecause stainless steel has many ideal properties required by building materials， it can be said to be unique in metals， and its development continues. In order to make stainless steel more neutral in traditional applications， existing types have been improved， and new stainless steel is being developed to meet the strict requirements of advanced architectural applications. Due to the continuous improvement of production efficiency and quality， stainless steel has become one of the cost-effective materials selected by architects. Stainless steel integrates performance， appearance and use characteristics， so stainless steel will still be one of the best building materials in the world.
— Good heat resistance， weak corrosion resistance， % Cr， % Ni.
tAfter hot rolling， it is subject to heat treatment and pickling treatment.
jVThe application range is wider than that of ferritic stainless steel. Compared with ferritic stainless steel， duplex stainless steel has the following disadvantages: high alloy element content and relatively high price. Generally， ferritic stainless steel does not contain nickel.
When selecting stainless steel water supply pipe， carefully observe whether the surface of the pipe is shiny， damaged and crushed， and pay attention to whether the incision is neat. If these phenomena occur， they should be carefully considered.
