Description
2000-600020-450 3000-6000
5, 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;
6,Mechanical Properties:
Tensile strength:σb (MPa):≥1080(110)
Yield strength:σs (MPa):≥930(95)
Elongation:δ5 (%):≥12
