Heat treatment Related
- Annealing of 16MnCr5|1.7147 Alloy gearing 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 16MnCr5|1.7417 gearing steel will get Hardness MAX 248 HB (Brinell hardness).
- Quenching and temperature of 20MnCr5 Alloy gearing steel
Heated slowly to 788°C, Then put in salt-bath furnace keep 1191 ℃to 1204 ℃.quenching by oil get 60 to 66 HRc hardness. High temperature tempering: 650-700℃,cool in air, get hardness 22 to 30HRC. Low temperature tempering: 150-200 ℃, Cool in ari, get 61-66HRC hardness.
- Hot work and cold work of 20MnCr5 gearing steel
DIN 20MnCr5 gear steel can hot worked at 205 to 538°C, 20MnCr5|1.7147 gearing steel can be cold worked using conventional techniques in the annealed or normalized conditions.
DIN 16MnCr5|1.7131 steel is widely used for a variety of applications in the used to the gearings 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.
