SNCM431 alloy steel manufacturers and suppliers,as forged supplied in Round Bars,Square/Flat Bars,Rollers,Shafts,Blocks,as rolled mainly provided in Round Rods.
SNCM431 steel is one kind of nickel-molybdenum alloy steel accding to JIS standard. SNCM431 steel is a heat treatable steel which contains nickel, chromium and molybdenum. SNCM431 alloy steel is known as its toughness and capability of developing high strength in the heat treated condition while retaining good fatigue strength. It is also a high strength steel and has good comprehensive mechanical properties.
Carbon:0.27/0.35; Silicon:0.15/0.35; Manganese:0.60/0.90;
Chromium:0.60/1.00; Molybdenum:0.15/0.30; Nickel:1.60/2.00;

JIS SNCM431 steel is widely used in the manufacture of the camshaft and connecting rod of engine parts, poor processability. SNCM431 steel is suitable for permanently stressed components with large cross sections for automotive and mechanical engineering.For economic performance under severe dynamic stress, parts must be designed for optimum strength or toughness.
1)Preheat SNCM431 forged alloy steel carefully.
2)Raise the forging temperature up to 1150-1200°C.
3)Keep the forging temperature above 850°C.
Hardening&Tempering(quenched and tempered and after stress relieved)
1)Heating SNCM431 steel uniformly to 850°C;
2)JIS SNCM431 alloy steel should be quenched in the oil;
3)Heat the material to the temperature 550°C;
4)Soak at this temperature for at least 2 hours;
5)SNCM431 alloy steel should be cooled in the furnace.
1)Heating SNCM431 forged steel thoroughly to 800-850°C;
2)Cool slowly to the temperature 550°;
3)Complete annealing the steel in the air.
1)Heat SNCM431 steel until the temperature up to 850°C;
2)Then cool SNCM431 steel down to the room temperature(20°C) in the air.
