以下是 我们的对话  
Can you tell me which grade you sell the more for medical product? I don't like H900 and H925. It is too hard and difficult to machine.(900 925太硬,他不喜欢)

The material is H900, I just send you a mail. I want to know your air cool H900 hardness. Is it come with lower HRc or as to the table of 40?(900的能否低于HRc40)

If HRc40, it is difficult to machine. So I require a material to be annealed to HRc less than 25. After machine, I will heat treat to HRc40. Pls check if you can supply HRc <25 for H900.( 低于HRc25最好,他那去加工到40)

H900 with HRc <25?(H900能达到小于25么)

总之他就是要硬度低一些的 好加工啊  但是我对这方面懂得不多    各位指教啊

H900是处理的工艺代号。
