HK30 is one Austenitic stainless steel casting metal in standard of ASTM A351 and ASTM A608. It can give good heat resistance properties.

Casting Methods in Casting Quality Industrial:

HK30 (UNS J94023) Equivalent Stainless Steel Grade: WWW.CASTINGQUALITY.COM

SS310 (UNS S310) have similar content of Chromium and Nickel, but the HK30 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.
CNC Machining
CNC Milling, CNC turning with 5 xix CNC center, we provide precision machining for all castings based on customers design drawings.
CAD Design
Mechanical Design service based on customers requirement, our software is Solidworks and AutoCAD.
Tools/Mold Design
