SAE4140/AISI4140 Alloy Steel
SAE4140/AISI4140 rank is a low-alloy stainlesss steel like chromium and molybdenum seeing that strengthening elements which will has excellent strength along with toughness, ductility, weldability in addition to machinability. SAE4140/AISI4140 is generally used in the automobile, agricultural, oil and natural gas industry. Normal uses usually are forged dresses and shafts, spindles, features, jigs as well as collars.Regulating For SAE4140
1. Minimal normalizing temp: 840-880°C
installment payments on your Hold typically the temperature for several a long time
3. Cooling in often the air
Annealing For SAE4140
1. Small Annealing heat range: 790-840°C
minimal payments Cool slowly but surely in the furance
a few. Maximum Brinell solidity involving 225
Hardening and also Tempering(QT) For SAE4140
one Tiny Hardening temperature: 830-860°C
two. Hold at this temperatures then quench in acrylic or water
3. Tempering as soon as likely when the temperature minimal to ambient
4. High temperature uniformly to the acceptable heat of 540-680°C
a few. maintain your material out connected with the furnace, in that case neat in the air
Pressure Minimize For SAE4140
one particular. Moderate Stress Relieve temp inside Quenched and Tempered situation: about 30-50°C down below the tempering temperature.
a couple of.. Nominal Strain Relieve heat range in the Annealed issue: 600-650°C
3. Cooling down with the air.
Mechanical Property( to get reference only)
just one. Tensile strength: 850-1000MPa
only two. Give point: Min665MPa
