Technical characteristics

High-speed steel grades are produced in accordance with GOST 19 265-73 standards. It is used in the production of metal-cutting tools which are designed for high-speed cutting. Fast-cutting grades are alloyed with tungsten, molybdenum, vanadium, cobalt, which provides high heat resistance, redness, wear resistance. Grades Р6М5, Р12Ф3, Р8М3К6С, Р8М3, Р8М5 and Р9 are used for fast-cutting tools production. They are advantageously distinguished by high heat resistance and have high calculated hardness.

Marking

The number following the letter "P" means the average tungsten content (of the total mass in percentage, the letter B is skipped). Then the letters M, K, F are followed by the percentage of molybdenum, cobalt, vanadium.

Alloying

Alloying has a multidimensional effect on steel quality. Chromium increases corrosion resistance. Nickel makes the alloy ductile; tungsten makes it wear-resistant and redresistant. Vanadium increases resistance to impact and abrasion. Molybdenum gives the alloy redness, strength, resistance to oxidation at high temperature. Manganese content above 1% increases impact strength, wear resistance. Titanium increases stability, corrosion resistance.
