430 stainless steel is a general steel with good corrosion resistance. Its thermal conductivity is better than austenite, its thermal expansion coefficient is smaller than austenite, its heat resistance fatigue, and the addition of stabilized element titanium has good mechanical properties at the welding seam.
420 stainless steel is a kind of martensiform stainless steel, with certain wear resistance and corrosion resistance, higher hardness characteristics, suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation vehicles, household appliances, etc. Mainly used in the manufacture of atmospheric, water vapor, water and oxidizing acid corrosion parts.
Stainless steel 410S is produced in accordance with the American ASTM standard of stainless steel, equivalent to China's 1Cr13 stainless steel, S41000 (AISI, ASTM).
Alloy 321 (UNS S32100) is stabilized stainless steel plate which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500°F (427 to 816°C). Alloy 321 stainless steel bar is stabilized against chromium carbide formation by the addition of titanium.
Alloy 316/316L resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments. It also resists corrosion in polluted marine atmospheres. The alloy has excellent resistance to intergranular corrosion in the as-welded condition. Alloy 316/316L has excellent strength and toughness at cryogenic temperatures.
310S stainless steel has superior high temperature resistance, weldability at high temperature, and is mostly used for high temperature structure. It is the first choice for high temperature applications.
Alloy 309S (UNS S30900) is an austenitic stainless steel developed for use in high temperature corrosion resistance applications. The alloy resists oxidation up to 1900°F (1038°C) under non-cyclic conditions. Frequent thermal cycling reduces oxidation resistance to approximately 1850°F (1010°C).
Stainless Steel 301 contain 17% chromium and 7% nickel, which offer high tensile strength up to 1800Mpa.
