These M35 High-Speed Steel Round Bar are supplied by us in accordance with DIN, ISO, JIS or ANSI Standard.
High Hardness: When correctly heat-treated, M35 steel reaches a high hardness of about 65-67 HRC. This property makes it well-suited for cutting tools, in which hardness is vital for keeping edges sharp.
Excellent Wear Resistance: It offers outstanding resistance to wear, a quality that is critical in high-speed cutting tasks where tools face severe friction and heat.
Good Toughness: Even with its high hardness, M35 steel retains good toughness. This blend of hardness and toughness aids in preventing chipping and fracture under conditions of high stress.
High Heat Resistance: M35 steel offers good heat resistance, enabling tools made from it to run at high speeds without softening or losing hardness because of heat.
Versatility: It is applicable to a range of cutting tool uses, such as drills, taps, milling cutters, and reamers. This adaptability makes it a favored option in industries that demand high-performance cutting tools.
M35 High-Speed Steel Round Bar uses are as varied as the industries they cater to, driven mainly by the aerospace, railway, construction and automotive sectors, along with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Yes,M35 high-speed steel round bars can be recycled. High-speed steels such as M35 hold considerable quantities of valuable metals like tungsten, molybdenum, and cobalt, which can be recovered through recycling processes. Recycling allows these materials to be retrieved for reuse, supporting sustainability and resource efficiency across manufacturing industries.
