Subcritical annealing:680~720â°c
Isothermal annealing:830~900 670x3hâ°c
Hardening:830~860 oil
Tempering:550~650â°c
3.Machanical properties
Tensile str. (n/mm2):1080
Yield point (n/mm2):930
Elongation (%):12
Contraction (%):45
Impack work (j/cm2):63
Hardness (hb):217
4.Characteristic of 40cr steel
Chromium molybdenum high tensile steel with yield strength of 550n/mm2.
Chromium renders steel oil hardenable and increase hardenability.
Weldability suffers with increasing chromium content.
High temperature strength and high pressure hydrogenation properties are
Promoted by chromium and molybdenum.
Molybdenum significantly reduces temper brittleness.
