Custom Stainless Steel Parts Manufacturer
As a foundry with over 10 years, HDC provides stainless steel castings for global customers across industries with unmatched expertise.
With our one-stop custom service from conception to final products and comprehensive casting processes(sand casting, investment casting, die casting), we can cast stainless steel products with complex structures and tight tolerance from a few grams to tens of kilograms.






Industries We Serve
Automotive Industry
HDC implements casting for complex auto parts that require excellent corrosion resistance and good heat resistance, such as supercharger parts and exhaust system.
Process Industries
The pump, valve, and pipeline system is the biggest stainless steel castings application area. HDC is an expert in casting these complex thin-walled parts.
Machinery Industry
Stainless steel castings support the machinery industry with their combined strength, corrosion resistance, and certain wear resistance
Stainless Steel for Casting
HDC provides a wide range of stainless steel for the casting process to satisfy various project requirements.
Austenitic stainless steel is non-magnetic, has excellent corrosion resistance and machinability, and is the type of stainless steel commonly used for casting.
- CF8(≈ 304): The most versatile cast austenitic stainless steel, containing 18% Cr-8% Ni.
- CF3(≈ 304L): A low-carbon version of CF8 (C≤0.03%), commonly used in the food sector
- CF8M(≈ 316): Adding 2%~3% Mo based on CF8, significantly improves the corrosion resistance to chloride, which is often used in chemical and marine fields
- CF3M(≈ 316L): The low-carbon version of the CF8M offers better weldability
Duplex stainless steel has a structure of about 50% austenite + 50% ferrite, which has high strength and excellent stress corrosion resistance.
Martensitic stainless steel is magnetic, generally corrosion resistant, and can obtain high strength and hardness through heat treatment.
CA15(≈ 410): Basic martensitic steel (12%Cr) for components that do not require high wear and corrosion resistance
Ferritic stainless steel has magnetic properties, good oxidation resistance, and sulfur corrosion resistance, but it has relatively poor strength and toughness.
- CB30( ≈ 430): Basic ferritic steel (17%Cr), mostly used in low corrosive environments
- CC50: High chromium ferrite steel (26%-30%Cr), excellent heat and oxidation resistance.
Precipitation hardening stainless steel has been aged to make it have both high strength close to martensitic steel, and good corrosion resistance close to austenitic steel.
CB7Cu-1(≈ 17-4 PH): High strength (yield strength >1000 MPa), excellent corrosion resistance, and dimensional stability, commonly used in aerospace applications and precision castings
