Product description

Carbon steel: GB45#/AISI 1045/ DIN 1.1191/JIS S45C

Chemical composition:

C: 0.42 to 0.50%
Si: 0.17 to 0.37%
Mn: 0.50 to 0.80%
P: ≤0.035%
S: ≤0.035%
Cr: ≤0.25%
Ni: ≤0.25%

Heat treatment temperatures:

Normalizing 850°C
Quenching 840°C
Tempering 600°C

Mechanical properties:

Tensile strength (Mpa): ≥600
Yield strength(Mpa): ≥355
Percentage Elongatier: ≥16%
Percentage reduction of area: ≥40%
Charpy impact test: ≥39J
Hardness (HBW): not heat-treated steel ≤229 and annealed steel ≤197
Thickness: 20 to 400mm
Width: 200 to 2,200mm
Length: 2,000 to 5,800mm
Round bar:
- Diameter: 20 to 400mm
- Length: 2,000 to 5,800mm
Tube:
- Outer diameter: 21.3 to 609.6mm ( 1/2 to 24-inch)
- W.T: 3 to 80mm
Process: EAF/LF/VD/forged/heat treatment/annealed/normalized/Q/T
Surface treatment: black, coated and galvanized or as your requirement
Test: ultrasonic test according to SEP1921-84C/C
Characteristic application
Strength is high, toughness is good, but the hardening capacity is low and is easy hardening crack when put it into water
Usually use for making higher hardness run part, blade wheel, piston, bearing, gear wheel and so on
Delivery state hot rolled and forging; EAF and ESR material black and machined annealing Hardness: HBS= 160 to 210
Packaging: according to the export standard or as client's requirements
