Requirements withstand greater load and a certain degree of tightness or corrosion resistance of the more important castings such as cylinder, gear, base, flywheels, bed, cylinder block, cylinder liner, piston, gear box, brake wheel, coupling Plate, medium pressure valve, etc.

G300 and G350
Under high load, wear and high air tightness important castings, such as heavy machine tools, shears, presses, automatic lathe bed, frame, frame, high-pressure hydraulic parts, piston rings, force larger gear, Cams, bushings, large engine crankshaft, cylinder block, cylinder liner, cylinder head, etc.
