Virat Special SteelsM35

Virat Special Steels is the leading Supplier & Stockiest of M35 Steel in India.
M35 is cobalt content material in these high-performance excessive-speed steel results in high pink hardness and tempering resistance. As a final result, this grade is primarily suitable for conditions involving thermal stresses and discontinuous cutting.
This grade is typically used as heavy-duty milling cutters of every kind, particularly stressed twist drills and taps, profile knives, machining of high-strength substances, broaches

Steel Properties

The cobalt content in this high-performance high-speed steel results in high red hardness and tempering resistance. As a consequence, this grade is particularly suitable for conditions involving thermal stresses and discontinuous cutting. Under the name Rapidur 3245, AISI M 35 + S and material number 1.3245, this steel grade is supplied with a higher sulphur content (S = 0.10 %).

Application

Heavy-duty milling cutters of all kinds, highly stressed twist drills and taps, profile knives, machining of high-strength materials, broaches.
