EN 10295 Grade GX40CrNiSi25-20, EN 1.4848
SS310
SS310 (UNS S310) have similar content of Chromium and Nickel, but the HK40 has high carton than SS310. SS310 is similar as CK20.
Reference Casting Standards and others:
ASTM A351 Standard Specification for Castings, Austenitic, for Pressure-Containing Parts
ASTM A608 Standard Specification for Centrifugally Cast Iron-Chromium-Nickel High-Alloy Tubing for Pressure Application at High Temperatures

- Sand Casting
Casting Quality focus on Metal Parts industry, we provide professional service in Metal Casting field.
Sand Casting is a popular metal form method, are suitable for all materiel, such as grey iron, ductile iron, malleable iron, carbon steel, stainless steel, aluminum and bronze.
- Investment Casting
also named as precision lost wax casting, mainly suitalbe for carbon steel and stainless steel parts. We also provide grey iron and ductile iron and aluminum and bronze parts by investment casting. It can achieve the best appearance with good tolerance
- Shell Casting
Shell casting method is a good option to replace investment casting and sand casting. the quality is better than sand casting parts, suitable for bulk production.
