ASTM A48 Class 30 Cast Iron Foundry in China

ASTM A48  Class 30 Cast Iron is the most common material of gray cast iron in USA,chemical composition and mechanical properties equivalent to HT250 in china.Class 30 cast iron is widely used in machine base, Machine tool bed,sprocket wheels, bases,Columns,cylinders,gears,flywheels, machinery bed, cylinder block, cylinder liner, piston, gear box, brake wheel, pump body,railway accessories,exhaust manifold and so on.

Class 30 Cast Iron has high tensile strength and hardness, high degree of tightness or corrosion resistance requirements. Minimum tensile strength 207 Mpa,Brinell hardness range 187 - 241 BHN.

Class 30 Cast Iron normal chemical composition should be C = 3.16-3.3%, Si = 1.79-1.93%, Mn = 0.89-1.04%, S =0.094-0.125%，P=0.12-0.17%.However, physical properties could be the inspection standard, but chemical composition is just the reference data from experience of iron foundries, which could not be the inspection specification.

Liaoning Tengfei Foundry has the special competitive prices of Class 30 Cast iron,its FOB China was about 1.16 USD/kg by green sand casting process, 1.35 USD/kg by resin sand casting process, and 1.45 USD/kg by shell molding process.Of course,these prices apply only to blank castings without machining.
