Product Description

High Speed Alloy Tool Steel Bar (M35/W6MoCr4V2Co5/1.3243/SKH35)

Features:
(1),For tungsten molybdenum containing cobalt high speed steel, improve the red hardness and high temperature hardness;
(2),Improved wear resistance, good machinability, but lower strength and impact toughness, easy oxidation decarburization;
(3),Commonly used for gear cutting tools, milling tools and tools such as punch, cutter for cutting hard material;

Application:
(1)Has good machinability, but lower strength and impact toughness;
(2)easy oxidation decarburization, commonly used for gear cutting tools, milling tools and tools such as punch,;
(3)cutter for cutting hard material;
