GB 20CrMnTi GB/T 3077 - BBN STEEL STORESGB 20CrMnTi GB/T 3077 In addition to carbon, steel also contains a small amount of manganese (Mn), silicon (Si), sulfur (S), phosphorus (P), oxygen (O), nitrogen (N) and hydrogen (H). These elements are not intentionally added to improve the quality of steel, but are brought in by ore and smelting process, so they are called impurity elements.The characteristics and applications of GBT 11251 30CrMo GBT 11251 30CrMo structural steel has high strength toughness and hardenability, the critical quenching diameter in oil is 15 ~ 70mm. And 30CrMo steel has good thermal strength. It has enough high temperature strength below 500, but its strength decreases at 550 degrees C. When the alloy elements are in the lower limit, the welding is quite good, but the welding is intermediate when the alloy elements content is close to the limit. 30CrMo structural steel
