विवरण
M1 is a molybdenum, chromium, vanadium alloy tool steel generally known as a Molybdenum High Speed Tool Steel. It is on of the most widely available tool steels in use today. It is similar in properties to the tungsten tool steels (T series) at a lower. Very tough high-speed Mo steel good grindability.
अनुप्रयोगों
Twist drills, thread cutting tools, hobs and dies for broaching and cold flow pressing, cross recess dies for screw manufacture, cold rolling for e.g. Sendzimir equipment.

सॉफ्ट एनीलिंग
820-850 को हीट करेंoC, cool slowly in furnace to 550oC then air. This will produce a maximum Brinell hardness of 262.
तनाव राहत
Stress relieving to remove machining stresses should be carried out by heating to 600-650oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.
सख्त
0 Harden from a temperature of 1180-1219oC followed by air or oil quenching or warm bath at 550oC. Hardness after quenching is 64-66 HRC.
टेम्परिंग
तापमान का तापमान: 530 - 560oC, at least 2x for at least 63 HRC.

गर्म बनाने का तापमान: 1100-900oC.
Cold Working
This alloy may be cold worked in the annealed condition.
मशीन की
M1 is classified as a “medium” machinable alloy. Machining should be accomplished prior to hardening heat treatment followed by finish grinding. It has a rating of 50% that of the water hardening (W group) low alloy tool steels in regard to machinability.
संक्षारण प्रतिरोध
This is not a corrosion resistant alloy. In use as tooling it is often coated with oil to prevent rusting. A light film of oil. or protective wrapping, is essential to keep it free from corrosion.
वेल्डिंग
Consult the alloy supplier for information on weld procedures.
