Heat treatment Related
- Annealing of SNCM435 Alloy structural steel
heated to 870 ℃ and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. The SNCM435 alloy steel will get MAX 250 HB
- Hardening of JIS Alloy structural steel SNCM435
First quenching heated slowly to 880°C, Then after adequate soaking at this temperature quench in oil or water. Temper as soon as tools reach room temperature. Second quenching heat to 780-820°C， then quenching in oil or water.
- Tempering of SNCM435 Alloy structural steel
Heat to 205-649°C, then cool in water or oil. normal delivery hardness 18-22 HRC.
- Forging of Alloy Steel SNCM435
JIS SNCM435 alloy steel is forged at 926 to 1205°C (1700 to 2200°F)
Mechanical Properties
The mechanical properties of annealed JIS SNCM435 alloy steel are outlined in the table below
| Tensile strength | Yield strength | Elongation | Reduction of area | Poisson’s ratio | Impact absorbing energy |
| σb/MPa | σs/MPa | δ5(％) | ψ(％) | AKV/J | |
| 1100-1300 | 900Min | 10 min | 40 min | 0.27-0.30 | 35 Min |
Applications
JIS SNCM435 steel Strength, high hardenability, toughness, and quenching small deformation, high strength and creep rupture strength at high temperatures. Requirements for the manufacture of higher intensity than the 35CrMo steel and tempered forging greater cross-section, such as a large locomotive traction gears, supercharger drive gear, pressure vessels, gear, rear axle, greatly affected by load and spring clip link It can also be used to 2000m deep oil drill pipe joints and fishing tools, and can be used benJISg machine mold, etc.
