产品介绍
10进口弹簧钢销售热线:许经理,具体规格及价格电询!
特性:SUP10具有良好的力学性能和工艺性能,淬透性较高,加入钒使钢的晶粒细化,降低过热敏感性,提高了强度和韧性,具有高的疲劳强度,屈服比也较高,但焊接性差,冷因变形塑性低。
Characteristics: SUP10 has good mechanical properties and process performance, quenching high, adding vanadium steel grain refinement, reducing overheating sensitivity, improves the strength and toughness, has high fatigue strength, yield ratio is relatively high, but the welding of poor, cold due to the plastic deformation of low.
