Product Description

SAE1045/S45C/1.1191 Hot Work Carbon Steel Bar

1045 steel is a medium carbon, medium tensile steel supplied as hot rolled, forged or normalized. Changfeng steel supply 1045 steel round bar, plate, steel rods, steel bars, flat bar, square, sheet.

1. Heat treament of SAE AISI 1045 steel
1)Forging: at 850°C - 1250°C, Hold until the temperature is uniform, Then Cool in furnace
2)Annealing:Heat to 800°C - 850°C , Slowly, Then Hold the temperature until uniform; Cool in heat treatment furnace.
3)Normalizing:Heat to 870°C - 920°C, Soak evenly, about Soak for 10 - 15 minutes, then Cool in air
4)Stress Relieving:Heat to 550°C - 660°C, Hold the temperature, Soak enough time, until thoroughly heat, then Cool in still air
5)Hardening:Heat to 820°C - 850°C, Soak for 10 - 15 minutes per 25mm of section, Quench in water or brine
6)Tempering:Re-heat to 400°C - 650°C as needs, Soak about 1 hours per 25mm of section, Cool in air.

2,Application:
Use for making injection plastic mould,mould frame and some middle-range machine.
1)Widely used in machine manufacturing;
2)For shaft parts ;
3)Stamping die drawing parts repair and hardfacing;

3,Chemical composition(%)

C	Si	Mn	P	S	Cr	Ni	Cu
