Technical characteristics

Brand high speed steel produced in accordance with the norms of GOST 19 265−73. It is used in the manufacture of cutting tools, which is designed for high speed cutting mode. High speed brand alloyed with tungsten, molybdenum, vanadium, cobalt, which provides high heat resistance, red hardness, wear resistance. Brand R6M5, R12F3, Р8М3К6С, Р8М3, Р8М5, P9 used for the production of high speed tool. Favorably great heat resistance, have a high estimated hardness.

Marking

Following the letter «R» number indicates the average tungsten content (by weight percentage, the letter is skipped). Then the letters M, K, f indicate the percentage of molybdenum, cobalt, vanadium.

Alloying

Alloying has a multifaceted effect on the quality of the steel. Chromium increases resistance to corrosion. The Nickel gives the alloy ductility; tungsten — wear resistance, red hardness. Vanadium increases the resistance to shock load and abrasion. Molybdenum alloy imparts red-hardness, strength, opposition to oxidation at high temperature. The proportion of manganese is above 1% increases the impact strength, wear resistance. Titanium increases the stability, corrosion resistance.
