 Second quenching temperature (℃): - 
 Tempering heating temperature (℃): 200; coolant: water, air 
 Tensile strength (σb / MPa): ≧ 1470 
 Yield point (σs / MPa): - 
 Elongation (δ5 /%): ≧ 10 
 Reduction of (ψ /%): ≧ 40 
 Impact absorbed energy (Aku2 / J): ≧ 47 
 Brinell hardness (HBS100/3000) (annealing or tempering condition): ≦ 269 
 [Main features] 
 Basically the same performance and 20SiMn2MoV steel. But the strength and hardenability slightly higher than 20SiMn2MoV, while slightly lower ductility and toughness. 
 [Application Examples] 
 Use the same steel with 20SiMn2MoV. With the steel rings and other parts of the oil rig with good performance, more 35CrNi3Mo and 40CrNiMo similar parts made more secure, reliable, and light weight, save material. 
 The company offers domestic and imported alloy steel varieties, complete specifications, special specifications can be customized processing.
