◆ stainless steel and alloy tool steel (C content is expressed in thousandths)， such as thousandth of CrNi (i.e.， such as CrNi， ultra low carbon C & le; .% if the international stainless steel mark， the American Iron and Steel Institute uses three digits to mark various standard grades of malleable stainless steel. Among them， austenitic stainless steel is indicated by numbers of and series，Stainless steel plate and ferritic and martensitic stainless steel is indicated by numbers of series. For example，Price of 316L stainless steel stripMake every effort to do a good job in the deep processing production line and stabilize the production some common austenitic stainless steels are marked with ， ， and ， ferritic stainless steels are marked with and ， martensitic stainless steels are marked with and C， duplex (austenitic ferrite)， stainless steels， precipitation hardening stainless steels and high alloys with iron content less than % are usually named by patent name or trademark.
4Stainless steel pipes are divided into hot rolled， hot extruded and cold drawn (rolled) stainless steel pipes according to the connection and rolling process. According to the difference of stainless steel microstructure，Stainless steel plate they mainly include semi Ferritic and semi martensitic stainless steel pipes， martensitic stainless steel pipes， austenitic stainless steel pipes， austenitic ferritic stainless steel pipes， etc.
iThe shape of pipe end stainless steel pipe can be divided into smooth pipe and threaded pipe (threaded steel pipe) according to the state of pipe end. Threading pipe can also be divided into ordinary threading pipe (pipe for conveying low pressure such as water and gas， which is connected by ordinary cylindrical or conical pipe thread) and special threaded pipe (pipe for petroleum and geological drilling， which is connected by special thread for important threading pipe). For some special pipes， in order to make up for the impact of thread on the strength of pipe end， the pipe end is usually thickened before threading (inner thickening， outer thickening or inner and outer thickening).
It has good local corrosion resistance. Compared with austenitic stainless steel with the same alloy content，Stainless steel plate its wear-resistant corrosion and fatigue corrosion properties are better than austenitic stainless steel.

Stainless steel has the ability of atmospheric oxidation， that is， it does not rust. At the same time， it also has the ability of corrosion resistance in the medium containing acid， alkali and salt， that is， corrosion resistance. However， its corrosion resistance changes with its own chemical composition，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 mutual state， service conditions and environmental medium type. For example has absolutely excellent corrosion resistance in dry and clean atmosphere， but it is moved to In coastal areas， in the sea fog with a lot of salt it will soon rust， while stainless steel performs well. Therefore， not any kind of stainless steel can resist corrosion and rust at any time
In the past few years， the United States has imposed anti-dumping and countervailing duties on a variety of steel pipe products exported from China including ring welded pipe， rectangular pipe， small-diameter pipeline pipe， welded stainless steel pressure pipe， the maintenance of stainless steel pipe should be strengthened in each process of consumption， mainly including the following three aspects: the processing and consumption of stainless steel pipe should have a special consumption workshop (wood board is well used) ， avoid indirect contact between austenitic stainless steel and carbon steel processing platform or solid air.
SThe specification and appearance quality shall comply with the provisions of gb- stainless steel seamless steel pipe. The steel pipe is usually ~ m long (indefinite length) hot rolled steel pipe， and the hot extruded steel pipe is equal to or greater than m. The wall thickness of cold drawn (rolled) steel pipe is . ~ mm， ~ m; the wall thickness is greater than mm ~ m.
BWhere can I find it?Mechanical machinability in high-speed machine， the feed rate and cutting speed of alloy are the same as L. If carbonization is adopted， the cutting speed is reduced by about % compared with L， and the performance of machinery and equipment and their components plays a key role here.
aCIn addition， when selecting the reasonable thickness of the steel plate， its service time quality and stiffness should be considered， easy processing and good ductility.
Inspection basisfChoose the price.
QEditors note on the causes of steel rusting: chloride ions exist widely， such as salt， sweat stains， seawater， sea breeze， soil， etc. stainless steel corrodes rapidly in the presence of chloride ions， even surpassing ordinary low-carbon steel. Chloride ions form complexes with Fe in alloy elements， and then being stripped of electrons and oxidized [].
The welding alloy has good weldability. Professional sales of stainless steel plate， stainless steel coil， stainless steel belt， stainless steel pipe， large quantity， high quality and low price. Fire resistance - Waterproof - high temperature resistance， 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， strength and toughness as the base metal. It is not difficult to weld， 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， it has lower coefficient of thermal expansion and higher thermal conductivity.

eV — Martensite (high strength chromium steel)， good wear resistance and poor corrosion resistance.
With the development of social economy， the application of stainless steel pipe has been more and more popular. It will bring new changes in various fields.
