Description
1) Weldability suffers with increasing chromium content;
2) High temperature strength and high pressure hydrogenation properties are promoted by chromium and molybdenum;
3) Molybdenum significantly reduces temper brittleness;
4) Chromium renders steel oil hardenable and increase hardenability;
5) Chromium molybdenum high tensile steel with yield strength of 550N/mm2
Applications
1) Suitable for manufacturing requirment a certain strength and toughness of large and medium-sized plastic mold, such as locomotive traction with the big gear, the supercharger drive gear, pressure vessle, rear axle, gear load connecting rod and a spring clip
2) Used to under 2000m deep well of oil drill pipe joint and the fishing tool
