Product Description
High Speed Tool Steel AISI M42 Hot Rolled Black Surface Round Steel
Product Introduction
M42 super high speed steel is a premium cobalt high speed steel with a chemical composition designed for high hardness and superior hot hardness. These properties make the steel an excellent choice for machining high-strength and pre-hardened steels, high-hardness alloys, and the difficult-to-machine, nonferrous super alloys used in the aerospace, oil, and power generation industries.
M42 exhibits excellent wear resistance by virtue of high heat-treated hardness (68 to 70 HRC), and the high cobalt content imparts the hot hardness. As such, the cutting
edges on tools made from M42 super high speed steel stay sharp and hard in heavy-duty and high-production cutting applications.
Chemical Composition
Features
Wear and abrasive resistance
• Can maintain cutting edge until 600c
• Easy to harden and can do vacuum hardening
• Provide high hardness after hardening (64-66 HRC)
• Resistance to annealing at high temperature
• High tensile as compare to AISID2
• High performance in cutting application. Can be applied to cut any kind of materials.
• High resistance to carbon losing at its surface
• Welding abiity
• Ablity to do hard surface by nitriding
• Ability to coating surface with PVD method.
Applications
Twist drills, taps, milling cutters, reamers, broaches, saws, knives, and thread rolling dies.
