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 […]

Solid solution treatment of stainless steel valves

Steel heating to 1050 ~ 1100 ℃, then rapid cooling in water, to get a single-phase austenitic organization, this process is called solution treatment. Solution treatment temperature should choose according to the carbon content of stainless steel, usually take limit at high carbon content, carbon content lower limit, but the temperature is unfavorable and exorbitant, […]

Three ways of welded steel pipe production

The first mode of production: the tube billet (plate, strip) is formed directly into the pipe, and its main process is the forming, welding and sizing of plate tape. Features: low production process, simple engineering process, short production cycle, low precision of product. The second mode of production: the tube billet welding (plate, belt) direct […]

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 […]
