The 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.
3 — Good heat resistance， weak corrosion resistance， % Cr， % Ni.
jAssembly: the sealing ring shall be correctly installed in the U-groove of the pipe fitting，316L stainless steel pipe put the pipe into the socket of the pipe fitting and wait for crimping.

KpThe stainless steel pipe installed on the pipeline support can be corroded by ppm chloride ion and ppm residual chlorine in an aerobic environment. For carbon steel structural supports， the pipeline shall be insulated to prevent corrosion due to potential difference， and the external insulation cotton shall be wrapped for anti-corrosion treatment. Remember， never use glue and other materials that contain chloride ions， when the stress exceeds the limit， even if the stress is no longer increased， the steel or sample continues to have obvious plastic deformation，316L stainless steel pipe which is called yield， and the small stress value when the yield phenomenon occurs is the yield point.
For the length of welding arc， ~ mm is better for ordinary steel welding， and ~ mm is better for stainless steel welding. If it is too long， the protection effect is not good.
yFirst of all， lets understand what stainless steel is. Generally speaking， steel that will not rust is called stainless steel but in an academic sense， steam and water and chemical corrosive media such as acid steel resistant to weak corrosive media such as air， alkali and salt. Also known as stainless acid resistant steel. In practical application， while the steel resistant to chemical medium is called acid resistant steel. Due to the difference in chemical composition between the two，316L stainless steel pipe the former is not necessarily resistant to chemical medium corrosion， while the latter is generally stainless. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel. Chromium is the basic element for stainless steel to obtain corrosion resistance. When the chromium content in the steel reaches about %，Nickel plated stainless steel stripTechnical equipment status of products chromium reacts with oxygen in the corrosive medium to form a thin oxide film (self passivation film) on the steel surface， which can prevent further corrosion of the steel matrix. In addition to chromium， the commonly used alloy elements include nickel， molybdenum， titanium， niobium， copper， nitrogen，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 so as to meet the requirements of various uses on the microstructure and properties of stainless steel.
V% of the thickness， and the large depth shall not be greater than .mm.

jPIn order to prevent the occurrence of welding pores， the welding parts must be cleaned if there is rust， oil stain， etc.
It is generally suitable for the welding of thin plates below mm， with the characteristics of beautiful weld formation and small welding deformation.
The length of tungsten electrode protruding from the gas nozzle is preferably ~ mm. In places with poor shielding such as fillet welding， it is ~ mm， and in places with deep groove， it is ~ mm. The distance from the nozzle to the working is generally no more than mm.
Latest quotationi% of the thickness， and the large depth shall not be greater than .mm.

According 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.

oCThe Chinese brand of stainless steel plate is crnimoti (CrNiMoTi with paper should also be this brand). The new brand is crnimoti stainless steel plate. The stainless steel plate is added with Ti in SUS steel to improve the intergranular corrosion resistance. It is applied to the equipment of， phosphoric acid， acetic acid and acetic acid.
Hot dip galvanized sheet hot dip galvanized sheet， which immerses the sheet into the molten zinc bath to make its surface adhere to a layer of zinc. It is mainly produced by continuous galvanizing process， that is， the rolled steel plate is continuously immersed in the zinc melting bath to make galvanized steel plate.
