Product Description
M41 W7Mo4Cr4V2Co5 High Speed Steel Tool Steel
1: M41 Steel Introduction
M41 high speed steel is a high quality high speed cutting steel with excellent cutting performance and wear resistance.M41 HSS has excellent hardness and cutting performance and is suitable for processes such as high speed milling, drilling and threading. Its high carbon content and suitable alloying element ratios ensure high hardness and wear resistance.M41 HSS has good machinability properties, including ease of cutting, resistance to high-temperature adhesion and thermal shock. During the cutting process, it is able to maintain low cutting forces and cutting temperatures, improving machining efficiency and quality.
