(it is divided into three categories: domestic SKD61, Taiwan nitride SKD61, Japanese vacuum nitride SKD61).Most customers will choose this material now, because of SKD61 material, has the high hardness and wear resistance after heat treatment, and have strong hardenability, good high temperature resistance, good dimensional stability characteristics, the commonly used material and mould thimble.

2. SKH51 material.

High speed steel material, usually at the top of the client to aimed at the requirement of hardness, SKD61 difficult to meet, will choose SKH51 material, SKH51 material in addition to having the advantages of SKD61, also has the red hardness of SKD61 have no.Although SKH51 thimble material is better, but because of high speed steel material's price is more expensive, and SKD61 material generally can meet the requirements of most mould thimble, so SKH51 thimble and less common than SKD61 thimble used.
