The distinction among 304, TP304, and 304L

304 stainless steel pipe with its good heat resistance, and is widely used in the production of corrosion-resistant and forming the equipment and mechanical parts. At present, 304 stainless steel pipe has been widely used in food, chemical, atomic and other industrial equipment and decoration areas. GB 304 Chemical composition: grades 0Cr18Ni9, C≤0.08, Si≤1.00, Mn≤2.00, P≤0.035, […]

317LXN

Allegheny Ludlum’s 317LXN™ is molybdenum-bearing austenitic stainless steel with greatly increased resistance to chemical attack as compared to the conventional chromium-nickel austenitic stainless steels such as Type 304. AL 317LXN™ alloy also offers higher creep, stress-to-rupture, and tensile strength at elevated temperatures than conventional stainless steels. The alloy has low carbon to provide resistance to […]

Discussion on Surface Treatment Technology of Stainless Steel

(1) preface: It is well known that stainless steel has its unique strength and high abrasion resistance and its excellent anti-rust properties. It is widely used in chemical industry, food machinery, electromechanical industry, household electrical appliance industry. At present, a lot of entering the home decoration industry, giving people the feeling of luxuriant nobility. The application of […]

Physical properties, mechanical properties and heat resistance of stainless steel

Physical properties of stainless steel Comparison of physical property data of stainless steel and carbon steel, carbon steel, the density is slightly higher than that of ferritic and martensitic stainless steel, and slightly lower than the austenitic stainless steel; resistivity by carbon steel, Ferritic, martensitic and austenitic stainless steel sort increment; linear expansion coefficient of […]

Surface of stainless steel processing grades, characteristics and uses

Surface finishing grades, characteristics and uses Original surface: NO.1 after hot rolling with heat treatment and acid treatment of the surface. Generally used in cold rolling materials, industrial tanks, chemical equipment, etc., the thickness is thicker than 2.0MM-8.0MM. Blunt surface: NO.2D cold rolling, after heat treatment and pickling, the material is soft, the surface of […]

The reaction of stainless steel and gas

Hydrogen corrosion may occur in ammonia synthesis, hydrogen desulphurization and oil refining. Carbon steel is not suitable for high pressure hydrogen device for above 232 ℃. The hydrogen diffusion into the steel, and in the grain boundary or pearlite zone and reaction of iron carbide and produce methane, the methane (gas) can’t spread to the […]
