30# carbon steel is used for hot forging and hot stamping mechanical parts, cold drawing, heavy and general machinery shaft, rod, collar, and mechanical castings, such as cylinder, turbine frame, rolling frame, machine frame, flywheel, etc.

35# carbon steel is used for hot forging and hot stamping mechanical parts, cold drawing and cold upsetting steel, structural parts in machinery, such as shaft, axle pin, lever, connecting rod, cross beam, sleeve, wheel rim, washer, screw, nut, rolled steel body, flywheel, equalizer, etc.

40# carbon steel is used as moving parts of machine, such as roller, shaft, crank pin, transmission shaft, piston rod, connecting rod, disc and axle.

45# carbon steel is widely used. It can be used as moving parts of steam turbine, compressor and pump, instead of carburizing steel to make gears, shafts and piston pins, etc. It can be used as structural parts of machinery or machine, and some can be used as die steel instead of tool steel.

50# carbon steel can be used as structural parts with high wear resistance and little dynamic load and impact, such as forged gear, pull rod, roller, shaft friction plate, plowshare, heavy load mandrel and shaft, etc.

55# carbon steel can be used as gear, connecting rod, wheel rim, flange, flat spring, roller, casting, etc.
60# carbon steel can be for roller, shaft, eccentric, spring coil, spring, washer, clutch, cam, wire rope, etc.

65# 70# carbon steel can be used as round and square spiral spring for general machines, drawn steel wire for small mechanical spring, train spiral spring, etc.; furniture, such as bed spring, etc.; seat cushion, interior decoration, etc.

75# 80# 85# carbon steel is high carbon content steel with high strength. Some of it may be used as general tools. It can also be used as round, square and flat springs for railway vehicles, automobiles, tractors and general machinery, as well as steel wires for other purposes. 85# steel can work under heavy load.
