Stainless steel is a acid-resistant steel for short, resistant to air, steam, water and other weak corrosive media steel, They are called stainless-steels.
Stainless steel often according to the organization state is divided into: martensitic steel, ferritic steel, austenitic steel, austenitic – ferritic (duplex) steel and precipitation hardening stainless- steels. In addition, according to the composition can be divided into: chromium Series, chrome-nickel series and chromium manganese nitrogen stainless-steels. Steel Grade as AISI/SAE 430, 304, 201, 202, Etc.
The most commonly used product is made of sheet and strip, also used in the heavy plate production of special products, for example, production of hot-rolled steel and extrusion structure steel structure. And circular, elliptical, square, rectangular and hexagonal welded pipe or seamless steel tube and other forms of products, including profiles, bars, wires, and casting. In order to meet the requirements of architects aesthetics, have developed a variety of commercial surface processing.
ASTM SAE 430 Stainless Steel | SUS430 | X6Crl7 | 1.4016
ASTM A580/A580M, JIS G 4303, GB/T 1220, EN ISO TR 15510
sae 430 Stainless steels grade is a non-hardenable steel containing straight chromium, and belongs to the ferritic group of steels. It be used for food grade utensil making. Like ice cream making mold steel, cup, food knife, shears,Used for building decoration, fuel burner components, home appliances, home appliance parts
Etc.
SAE 440C Stainless Steel | SUS440C | 11Crl7(9Crl8)
ASTM A580/A580M, JIS G 4303, GB/T 1220, EN ISO TR 15510
stainless-steels Grade 440C is a high carbon martensitic stainless steel. It has high strength, moderate corrosion resistance, and good hardness and wear resistance.
Mainly used in the manufacture of the corrosion environment and no lubrication bearing working parts in strong oxidizing atmosphere. 440 c high temperature has good dimensional stability, so also can be used as a corrosion resistant high temperature bearing steel. In addition, can also be used to manufacture high quality tools, such as medical scalpel, scissors, nozzle, bearings, etc. 440 c under dynamic load capacity is low.
