Chemical Composition(%)
| C | Si | Mn | P | S | Cr | Ni | Cu |
| 0.18~0.23 | 0.15~0.35 | 0.60~0.85 | ≤0.030 | ≤0.030 | 0.90~1.20 | 0.15 - 0.25 | ≤0.030 |
Heat treatment Related
Slowly heated to 850 ºC and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. The SCr420 alloy steel will get MAX 250 HB (Brinell hardness).
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.
Heat to 20°C, then cool in water or oil.normal delivery hardness 179HB Min.
Mechanical Properties
The mechanical properties of annealed JIS SCr420 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 | |
| 835 | 540 | 10 min | 40 min | 0.27-0.30 | 47 Min |
Applications
JIS SCr420 steel is widely used for a variety of applications in the used in the automotive and engineering industries for toolholders and other such components. Mostly used in the manufacture of the demand is higher, intensity of heart surface wear, under section under 30 mm or small carburized parts of complex shape and load (oil quenching), such as: transmission gear, gear shaft, CAM, worm, piston pin, claw clutch, etc.; For the heat treatment deformation and high abrasion resistance parts, should be high frequency surface quenching after carburizing, such as modulus is less than 3 of the gear, shaft, spline shaft, etc. This steel can be used in the quenched and tempered state and used in the manufacture of large and medium under impact load in her work parts, this kind of steel also can be used as a low carbon martensite steel quenching, further increasing steel yield strength and tensile strength increased (about 1.5 ~ 1.7 times). Typical applications such as valve bodies, pumps and fittings, Shaft, the high load of wheel, bolts, double-headed bolts, gears, etc
