Five properties of 40Cr low-alloy high-strength steel
Five properties of 40Cr low-alloy high-strength steel plate At present, the application effect of 40Cr low-alloy high-strength steel plate in the industrial field is very good. Its usability is very convenient and does not need heat treatment.
The difference between 45# steel and 40Cr, 42CrMo 45# is high quality carbon structural steel, carbon content is 0.42-0.50%, with 610 Mpa tensile strength , and yield point is 360 Mpa; 45# steel is widely used in machinery manufacturing, mechanical properties of this steel
42CrV6 is a kind of alloy structural steel .Quenched and tempered steel, having high strength and high yield, mechanical properties better than 40Cr. Cold deformation plasticity and machinability belong to medium, thermal sensitivity is small, but
40Cr is the standard grade of GB in China, 40Cr steel machinery manufacturing is one of the most widely used steel. After quenching and tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity.

The difference between 45# steel and 40Cr, 42CrMo - Jaway
45# steel is widely used in machinery manufacturing, mechanical properties of this steel is very good, so it’s generally used as axial parts. 40Cr is alloy structural steel, carbon content is 0.37-0.45%,0.8-1.1% chromium, 1000 Mpa tensile strength, yield strength is 800 Mpa; generally used to parts which can be loaded with large force.
After quenching and tempering, 40Cr steel plate has good comprehensive mechanical properties, good low temperature impact toughness, low notch sensitivity, good hardenability and high cold oil fatigue strength. When 40Cr steel plate is cooled by water, the shape of parts is complex, easy to produce cracks, and the cold bending plasticity is medium.
