问 :我们正在寻找一种E5 2 10 0球化退火圆钢的替代材料。我们将E5 2 10 0圆钢火焰淬火至 6 2～ 6 5HRC的硬度 ,用作切纸砧和切割砧。这批圆钢棒料中 ,有些直径为 88.9～ 139.7mm ,长度为 190 5mm ;有些直径为 4 0 6 .4mm ,长度为 14 2 2 .4mm。现在的问题是在原锻件上偶然发现
Q: We are looking for an alternative material for E5 2 10 0 spheroidized annealed bar. We flame the E5 2 10 0 round steel to a hardness of 6 2 ~ 6 5HRC and use it as a paper cutting anvil and cutting anvil. Some of these round bar stockings have diameters of 88.9 to 139.7 mm and lengths of 190 mm; some have a diameter of 406.64 mm and a length of 1422.4 mm. The problem now is the accidental discovery on the original forgings
