Process performance inspection: flattening test，stainless steel tube tensile test，Ocr25Ni20 stainless steel platePrecautions during maintenance impact test， flaring test， hardness test， metallographic test bending test and nondestructive testing (including eddy current testing， X-ray testing and ultrasonic testing).
CSanta RitaIn order to ensure that the mechanical properties such as yield strength， tensile strength， elongation and hardness of various stainless steel coils meet the requirements， the stainless steel coils must undergo heat treatment such as annealing， solution treatment and aging treatment before delivery. The corrosion resistance of stainless steel coil mainly depends on
YoThe Ministry of Commerce announced that the European Commission announced that it would impose a final anti-dumping duty of % ~ % on Chinas stainless steel seamless steel pipes exported to Europe，stainless steel tube which made the steel pipe enterprises already under the pressure of domestic and foreign troubles worse.
(I) The output reached a record high. From January to June， ， the country produced million tons of crude steel， an increase of % year-on-year， an increase of percentage points over the same period last year. In the first six months， equivalent to the level of . billion tons of crude steel. Among them， it reached a record high of . million tons in February. Although it fell from March to June， it still remained at a high level of more than . million tons. From January to June， according to provinces and regions The crude steel output of Hebei and Jiangsu increased by % and % respectively year-on-year. The total new output of the two provinces accounted for % of the national increase of . million tons. In addition， Liaoning the output of Shanxi，stainless steel tube Henan and Yunnan also increased by more than million tons. According to the types of enterprises， the crude steel output of key large and medium-sized iron and steel enterprises increased by % year-on-year from January to June，Ocr25Ni20 stainless steel platePrecautions during maintenance percentage points lower than the national average increase. They specialize in the sales of L stainless steel pipes and s stainless steel pipes Stainless steel pipe， L stainless steel pipe has high pressure resistance grade， good waterproof performance， fire resistance， high temperature resistance， strong overload capacity， corrosion resistance， radiation protection and long service life. However，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 is still years old
: stainless steel strip (stainless steel coil): or coil， coil， coil， plate coil. There are many names， and the hardness of the strip also varies from dozens to hundreds. Customers need to determine which hardness to use before purchasing. (K mirror luminosity)
oWith high torsional strength， it has also become an important material in various machinery and building structures. Structures and components made of stainless steel tubes have greater section modulus than solid parts under the condition of equal weight. Therefore， stainless steel pipe itself is a kind of economical section steel to save metal. It is an important part of steel， especially in petroleum drilling and production， followed by geological drilling chemical industry， construction industry， machinery industry， aircraft and automobile manufacturing， boiler， medical equipment Furniture and bicycle manufacturing also need a large number of various steel pipes. With the development of new technologies such as atomic energy， rocket， missile and aerospace industry， stainless steel pipe plays an increasingly important role in national defense industry， stainless steel stamping belt， stainless steel precision belt， stainless steel mirror belt， stainless steel cold rolling belt， stainless steel hot rolling belt， stainless steel etching belt， stainless steel polishing belt， stainless steel soft belt， stainless steel hard belt stainless steel medium hard belt， stainless steel high temperature resistant belt， which is mainly used for industrial transmission pipelines and mechanical structural components such as petroleum， chemical industry， medical treatment， food， light industry， etc. In addition， when the bending and torsional strength are the same， the weight is light， so it is also widely used in all kinds of manufacturing mechanical parts and engineering structures.
dCThe pipe fittings must rotate slowly facing the pipe. If they are tight， please use clean water pipe fittings and sealing rings.
Air 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.
cold rolled oriented silicon steel strip (sheet) represents: times of DQ + iron loss value (at the frequency of Hz， the magnetic induction peak with sinusoidal waveform is the unit weight iron loss value of T) + times of thickness value. Sometimes G is added after the iron loss value to indicate high magnetic induction. For example， dq represents cold-rolled oriented silicon steel strip (sheet) with iron loss value of and thickness of .mm. Now the new model is q.
installsStainless steel tube toxic chromium and nickel is not bad for you? Stainless steel contains a lot of chromium and nickel. Why is stainless steel still? The following Tianjin stainless steel pipe factory will answer for you: food grade stainless steel pipes will be corroded into spots for a long time if they are not soaked in acid (vinegar) and salt for a long time. Good stainless steel is a model and never rusts.
PLow temperature processing of stainless steel pipe --- martensite series stainless steel is quenched from austenitizing temperature and then cooled to very low temperature to promote martensite quenching. It is suitable for stainless steel easy to produce residual austenite.
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 ℃.
aStainless steel with domestic (imported) stainless steel belt: stainless steel coil， stainless steel spring
cLCompared with traditional steel， stainless steel can not only ensure high strength and weight ratio， 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!
