Kanish Metals is a premier producer and supplier of High Speed Steel M35 Bars, headquartered in Dubai, UAE, offering premium tool steel solutions for high-performance cutting and machining applications. M35 is a cobalt-containing high speed steel with superior red hardness, wear resistance, and toughness. Kanish Metals offers precision-engineered M35 bars according to international standards, suitable for high-demand industrial tooling applications. With great emphasis placed on quality consistency, tailored sizes, and timely delivery, Kanish Metals supplies industries like automobile, aviation, die and mold, and general engineering within the UAE and international markets.
High Speed Steel M35 contains about 0.9% carbon, 5% cobalt, 6% tungsten, 5% molybdenum, 4% chromium, and traces of vanadium. The presence of cobalt considerably enhances hot hardness, so M35 can sustain cutting edges over 600°C temperatures. It generally achieves hardness values ranging from 64–66 HRC upon heat treatment and provides excellent abrasion resistance as well as compressive strength. These characteristics make M35 highly sought after for cutting tools that need to withstand high-speed cutting and thermal stress without losing strength or edge retention.

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.
High Speed Steel M35 Bars find extensive usage in the manufacture of cutting tools that are required to work under severe heat and pressure. Typical uses are twist drills, end mills, taps, broaches, saw blades, reamers, and other sharp cutting tools. M35 is particularly ideal for cutting hard materials such as stainless steel and high-alloy steels. It also finds application in die-making, cold forming, and other high-load operations. The high red hardness, toughness, and wear resistance of M35 bars in combination ensure that these bars are a dependable tool material requiring both performance and durability at hard working conditions.
