SKH51 thimble has better toughness than SKD61; SKD61 thimble can withstand high temperature of 1600℃, and the surface of SKD61 thimble can improve the wear resistance of thimble after nitriding. 65Mn thimble is of poor quality, brittle and easy to break. Some plastic molds are no longer assembled and used with 65Mn thimble.
