硬质工具钢【T1圆钢】高温耐磨性工具钢
Characteristics and scope of application: ASTM T1 is the most widely used tungsten is a general type of high speed steel, high temperature hardness and red hardness and hardness is high, easy to grinding. ASTM T1 applicable for working temperature below 600 ℃ can still keep the cutting performance of cutting tools, such as vehicles, shaver, milling, reaming, broach, drilling, gear cutting tools and tap, die, etc., ASTM T1 is suitable for processing soft or medium hardness (300 ~ 320 hb) materials and production of high temperature wear resistance of machine parts.
高速钢具有高硬度、高耐磨性和高耐热性的工具钢，又称高速工具钢或锋钢
因此主要用来制造复杂的薄刃和耐冲击的金属切削刀具，也可制造高温轴承和冷挤压模具等。
ASTM T1化学成份：
碳 C ：0.65～0.80(允许偏差:±0.01)
硅 Si：0.20～0.40(允许偏差:±0.05)
锰 Mn：0.10～0.40(允许偏差:+0.04)
硫 S ：≤0.030
磷 P ：≤0.030
铬 Cr：3.75～4.50(允许偏差:±0.05)
镍 Ni：允许残余含量≤0.30
铜 Cu：允许残余含量≤0.25
钒 V ：0.90～1.30(允许偏差:±0.05)
钼 Mo：≤0.30(允许偏差:尺寸≤6,±0.05;尺寸＞6,±0.10)
