0.38~0.450.17~0.370.60~0.900.90~1.200.15-0.250.0180.0300.012


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;
 
3.Mechanical Properties:
Tensile strength:σb (MPa):1080(110) 
Yield strength:σs (MPa):930(95)
