 Mechanical properties 
 ● Mechanical Properties: 
 Tensile strength σb (MPa): quenching and tempering, ≥ 540 
 Conditions yield strength σ0.2 (MPa): quenching and tempering, ≥ 345 
 Elongation δ5 (%): quenching and tempering, ≥ 25 
 Reduction of area ψ (%): quenching and tempering, ≥ 55 
 Impact energy Akv (J): quenching and tempering, ≥ 78 
 Hardness: Annealed, ≤ 200HB; quenching and tempering, ≥ 159HB 
 ● 1Cr13 quenching temperature :1000-1050 degree heat 1-3 hours, air-cooled, according to high and low temperature tempering, the hardness will be different. 
 580-650 degree of tempering, water hardness is 254-302 HBS 
 560-620 degree of tempering, water hardness is 285-341 HBS 
 550-580 degree of tempering, water hardness is 254-362 HBS 
 520-560 degree of tempering, water hardness is 341-388 HBS 
 Less than 300 degrees tempering, air-cooled, hardness greater than 388 HBS 
 Heat treatment process
