316 stainless steel contains molybdenum added on the basis of 304 grade, delivering markedly improved resistance to pitting and crevice corrosion. It is particularly suitable for harsh corrosive working conditions such as seawater, chemical acids and alkalis, making it the preferred material for high-end precision castings.

WCB is a general-purpose carbon steel material featuring high strength and toughness with moderate cost. It is widely applied to precision castings such as valves and pump bodies operating under medium-low temperature and non-corrosive service conditions, boasting outstanding cost performance.

Grade 304 is the most commonly used austenitic stainless steel. It features excellent corrosion resistance, heat resistance and mechanical properties. Widely adopted in food processing, chemical industry, water treatment and other sectors, it serves as a fundamental material option for investment casting.

Grade 45 high-quality carbon structural steel features high strength and excellent wear resistance. It can achieve superior comprehensive mechanical properties after heat treatment, and is widely used for precision castings with high strength requirements such as mechanical structural parts, gears and shafts.

17-4PH is a precipitation hardening stainless steel featuring high strength, high hardness and favorable corrosion resistance. Its mechanical properties can be greatly enhanced via heat treatment, and it delivers excellent dimensional stability. It is applicable to high-end precision castings such as structural components, valve bodies and impellers that require high strength, wear resistance and corrosion resistance simultaneously.

Materials such as 42CrMo4, 20CrMo, 1.2798, 1.4301 and 416 are available. Feel free to inquire.

1.4409 duplex stainless steel combines the advantages of austenitic and ferritic stainless steels. It boasts high strength and excellent resistance to stress corrosion cracking, making it suitable for extreme working conditions with high pressure and heavy corrosion in oil, gas, chemical and other industries.

316L is a low-carbon molybdenum-containing austenitic stainless steel with outstanding corrosion resistance, pitting resistance and weldability. Its lower carbon content effectively prevents intergranular corrosion. Suitable for harsh corrosive environments such as seawater, chemicals, acids and alkalis, it is widely used in precision castings including valves, pump bodies and flanges.
