CG8M is one 19 Cr/11 Ni with Mo stainless steel grade which listed in ASTM A351 and ASTM A743 and ASTM A744 standard. Casting UNS number is J93000. CG8M is much better than CF8M because it has 3%-4% content of Molybdenum but CF8M only has 2%-3% Mo. WWW.CASTINGQUALITY.COM

- 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.
