ASTM A312 TP304, Stainless Steel Seamless Pipe For Oil and Gas Corrosion Resistance Application
Wenzhou Shangle Steel Co., Ltd. (Shangle) founded in 2017,is a comprehensive company integrating
industry and trade.As a leading supplier of stainless steel
products in Wenzhou, it has a wide range of products in stock that
have been rigorously tested and are ready to be shipped.
Description :
TP304 stainless steel is a common seamless steel pipe material,
this kind of steel pipe has excellent corrosion resistance and high
temperature performance, which is widely used in petroleum,
chemical, electric power and other fields.
The chemical composition of TP304 stainless steel mainly includes
iron, chromium, nickel and other elements, of which the chromium
content is generally between 18% and 20%, and the nickel content is
between 8% and 11%. The mechanical properties of this stainless
steel are related to the purity and thickness of the steel,
generally the tensile strength is between 400MPa and 650MPa, the
yield strength is between 200MPa and 400MPa, and the elongation is
between 30% and 60%.
Characteristic:
Corrosion resistance: 304 stainless steel has good corrosion
resistance and can be used under a variety of corrosive media,
including acids, alkalis, salts and other chemicals.
High temperature resistance: they can work for a long time in high
temperature environments and can withstand the impact of high
temperature steam and high temperature gases.
Strength and toughness:they have high strength and excellent
toughness, able to withstand high pressure and shock loads.
Easy to process : they are easy to process into various shapes and
sizes and have good welding performance.
