U.S. the Fen Coke O1 deformation wear oil steel 

 O1 This is a very wide range of excellent steel, used as a blade material can be processed very tough and depth of grinding blade. Randall knives and Mad Dog 01. 

 O1: the most widely used oil hard level (Oil-Hardening types) tool steel is used, of which the best is the O1 type, its high manganese with the same chromium and tungsten to increase hardenability steel without severe water quenching (on behalf of the Jiang Bunting oil quenching) can also be hardened to high hardness (HRc62) level. 
 O1: the processing of steel and good, but the toughness and endurance is weak. Use it to create the blade can be well suited to everyday use; and the heat treatment is very easy. 

 O1: the blade to maintain very strong. Generally speaking, all 01 can be polished very fine, it is very tough, you can rest assured polished. 

 Purposes: 

 O1 U.S. standards are not oil deformation of steel, the best oil hardened tool steel, widely used, 

 O1 of the steel has good processing properties, good wear resistance, 

 O1 heat stable performance, the size of deformation is small, but the toughness and corrosion resistance is weak. Commonly used in the stamping die, stamping die, bending die, die, perforated punch, finishing molds for metal molds. 

 Die cross section is small and complex shape, and a variety of measuring tools used to make. 

 Performance and application: 

 Low-alloy cold work die steel, Europe hardenability and wear resistance, hardening deformation is very small, uniform distribution of carbon compounds and small particles 

 Chemical composition: 

 (C :0.85-0 .95) (Si: ≤ 0.40) (Mn :0.90-1 .20) (Cr :0.50-0 .80) (P: 0.030) (S: 0.030) (W :0.50-0 .80)
