Brief:16MnCr5 grade steel is a case hardening steel used extensively for both carburising and carbonitriding, demonstrating reasonably high hardenability and excellent forgeability.
Brief:40CrNiMoA alloy structural steel is made of high-quality carbon structural steel by adding one or several alloying elements (total content not exceeding 5%). Common quality defects of bearing parts after heat treatment include: quenching microstructure overheating, underheating, quenching cracks, insufficient hardness, heat treatment deformation, surface decarburization, soft spots, etc.
Brief:1045 refers to the medium carbon quenched and tempered structure Steel. The cold plasticity of this steel is average, and annealing and normalizing are slightly better than quenching and tempering. It has high strength and good machinability. After appropriate heat treatment, it can obtain a certain degree of toughness, plasticity, and wear resistance
Brief:19CN5 is the introduction of foreign Cr-Ni series of steel, is the transmission of important surface hardening steel. 19CN5 has a higher strength and toughness, better machinability and forging, rolling hot workability, the relative thermal deformation smaller, but poor weldability and corrosion resistance.
Brief:20MnCr5 is a case-hardening steel with low carbon content but good hardenability reaching good wear resistance due to high surface hardness after hardening. The small grain size benefits in good ductility and fatigue strength.
Brief:High temperature components such as turbine blades, guide vanes, turbine disks, high pressure compressor disks,machine manufacturing and combustion chambers used in the manufacture of aviation, naval and industrial gas turbines
Brief:31CrMoV9 is a steel which in general is intended for the fabrication of quenched and tempered parts, which are generally machined and subsequently nitrided.
Brief:It is mainly used for nitrided parts with precise dimensions after heat treatment, or various nitrided parts with low impact load and high wear resistance. Such as boring bar, grinding machine spindle, automatic lathe spindle, worm, precision screw, precision gear. And also such as High-pressure valves, valve stems, gauges, templates, rollers, replicas, cylinder blocks, compressor piston rods, governors on steam turbines, rotating sleeves, fixing sleeves, various wear-resistant parts on rubber and plastic extruders, etc.
