1, Application
It used for section large forgings, such as locomotive traction
gears, with supercharger drive gear, the rear axle, the connecting
rod and the spring load greatly clip,oil drill pipe joints and
fishing tools,etc.
2, Feature
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.
