Yes, High-Speed Steel M35 can be welded, but it requires careful control of heat and preheating. Post-weld heat treatment is often necessary to restore its hardness and performance.
Yes, High-Speed Steel M35 bars can be customized in terms of dimensions, shape, and surface finish. Machining and heat treatment processes can also be tailored to meet specific performance requirements.
High-Speed Steel M35 bars should be stored in a dry, cool environment, away from moisture and extreme temperatures. They should be kept on racks to prevent contact with corrosive materials.
M35 bars are commonly used in the production of cutting tools that require superior heat resistance and durability. Typical applications include drills, taps, end mills, reamers, broaches, and saw blades designed for machining tough materials like stainless steels and high-strength alloys. They find their place in various industries, including automotive, aerospace, tool-making, and general engineering. Thanks to their well-balanced toughness, wear resistance, and hot hardness, M35 bars ensure a long tool life and consistent performance in demanding machining environments.
