ASTM A600 M35 steel is a medium-alloyed high speed tool steel. It is also known as HSSE or HSS-E which is similar to M2, but with 5% cobalt added, which makes better hot hardness and wear resistance. M35 steel is high speed tool steel. It also is called SKH55 steel and 1.3243 steel. After the heat treatment, its hardness, red hardness and wear resistance can be improved. And the hardness can up to 67-70HRC.
