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 […]
Application area and characteristics of 304 stainless steel pipe
The 304 stainless steel pipe is the most widely used for stainless steel, the equipment for food, general chemical equipment, and the atomic energy industry. 304 stainless steel pipe is a kind of common stainless steel pipe, it is widely used to make for a good comprehensive performance, corrosion resistance and formability of equipment and parts. The […]
Introduction of stainless steel chemical polishing solution
Additives have the effect of inhibiting corrosion and increasing light. It can form a complicated adsorption layer on the surface of stainless steel, activate the microconvex point on the surface of the parts, and blunt the microconcave point to make the polishing effective. Refers to this kind of additive of polishing fluid viscosity regulator, corrosion […]
The cutting performance of 904L stainless steel
The 904L stainless steel number is 00cr20ni25m02.5cu, which is a highly alloyed super-austenitic stainless steel with low carbon content. In dilute sulphuric acid, there is a good corrosion resistance, and the addition of copper makes it very resistant to acid, designed for harsh conditions. So this kind of stainless steel is used mainly for the manufacture 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 […]
