1. Quality standard   AISI, GB,

2.Delivery    as clients' requirements; on time delivery.

3. The steel is of good tenacity, heat intensity, heat weary property and abrasion.

4. The steel is used to make casting die and hot extrusion die , tool for punching, mandril, press machine of forging die and plastic mould, etc.

5.Because of its mesothermal intensity, it is also used to make mechamical part of airplane and rocket which can bear 400-500 degree.
