GCr15 Bearing steel

5/5

GCr15 steel is one of the most commonly used Chinese bearing steels, it’s a high carbon chromium bearing steel with high hardenability, high & uniform hardness after heat treatment, high contact fatigue strength, good dimensional stability and corrosion resistance. The cold deformation plasticity is medium, the machinability is general, the weld ability is poor, and it is sensitive to the formation of white spots, and there is a first type of temper brittleness.

GB GCr15 bearing steel, we can supply the round bar, steel flat bar, plate, hexagonal steel bar and steel square block. GB GCr15 steel Round bar can be sawn to your required lengths as one offs or multiple cut pieces. GCr15 bearing steel Rectangular pieces can be sawn from flat bar or plate to your specific sizes. Ground tool steel bar can be supplied, provide a quality precision finished bar to tight tolerances.

Heat treatment Related

Annealing of GCr15 Alloy bearing steel

Slowly heated to 790-810 ℃ and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. Different annealing ways will get different hardness.The GCr15 bearing steel will get Hardness MAX 248 HB （Brinell hardness）.

Quenching and temperature of GCr15 Alloy bearing steel

Heated slowly to 860°C, Then quenching by oil get 62 to 66 HRc hardness. High temperature tempering: 650-700℃，cool in air, get hardness 22 to 30HRC. Low temperature tempering: 150-170 ℃， Cool  in ari, get 61-66HRC hardness.

Hot work and cold work of GCr15 Alloy bearing steel

GB GCr15 steel can hot worked at 205 to 538°C, GCr15 Bearing steel can be cold worked using conventional techniques in the annealed or normalized conditions.

GB GCr15 steel is widely used for a variety of applications in the used to the bearings in rotating machinery. Typical applications such as valve bodies, pumps and fittings, the high load of wheel, bolts, double-headed bolts, gears, internal combustion engine. Electric locomotives, machine tools, tractors, steel rolling equipment, boring machine, railway vehicle, and mining machinery transmission shaft on the steel ball, roller and shaft sleeve, etc.
