12CrNi3A steel is alloyed carburizing steel,
which has higher hardenability than 12CrNi2A steel.
Therefore, it can be used to manufacture parts with slightly larger cross sections than 12CrNi2A steel
.Low temperature toughness, small notch sensitivity

Production Introduction

EN36/BS970 655M13/AISI 9315/DIN1.5752/GB 12CRNI3 Alloy Steel bar

• Low temperature toughness, small notch sensitivity

• After the steel quenching tempering at low temperature or high temperature tempering has good comprehensive mechanical properties, good low temperature toughness of steel, the notch sensitivity, machinability is good, when the hardness is HB260 ~ 320 ~ 70 in addition, the relative cutting processability was 60% steel annealing at low hardness, plasticity is good, therefore, either by adopting the method of machining manufacturing mold, Cold extrusion molding can also be used to manufacture molds. In order to improve the wear resistance of the mold cavity, the mold needs to be carburized after forming, and then quenching and low temperature tempering, so as to ensure that the surface of the mold has high hardness, high wear resistance and the core has good toughness, the steel is suitable for manufacturing large and medium-sized plastic mold. But the steel has the tendency of tempering brittleness and forming white spots.

Production Introduction

Senior carburizing steel is used widely, compared with 15 cr, 20 cr steel, the strength, plasticity, high hardenability.Mainly used to make heavy load conditions require high strength, high hardness and high toughness toughness high spindle and requirements of center or under impact load, small surface wear resistance, heat treatment deformation of shaft, rod and working under high speed and impact load of all kinds of transmission gear, screw, camshaft
