摘要
为了提高冷作模具的使用寿命，研制了新型冷作模具钢JK2（7Cr5Mo3SiV）。试验结果表明，该钢具有较高的强韧性，抗压强度与Cr12钢和高速钢相近，而抗弯强度和冲击韧性则优于Cr12钢和高速钢。
To increase the service life of cold work dies, a new type cold work tool steel JK2 (7Cr5Mo3SiV) has been developed. Results show that this steel has excellent strength and toughness.Compared with Cr12 and high speed steels,JK2 has about the same compression strength but better
