1.2711 (54NiCrMoV6) is a high carbon Nickel - Chromium - Molybdenum - Vanadium cold work alloy tool steel, 1.2711 is widely used to produce the cutting tool, cold/heat distortion mould, Mechanical parts, Air hammer tools, Piercing tools.
ALLOY TOOL STEEL - DIN 54NiCrMoV6 & W-Nr 1.2711
MATERIAL CATEGORY: Cold work alloy tool steel
Cold work die includes cold punching mould, wire-drawing die, drawing die, coining die, thread rolling die, cold heading die, cold extrusion die, Based on the working condition, cold work die should have the high hardness, strength, abrasion resistance, toughness, hardenability, quenching degree, and other processing property. This kind of alloy tool steel belongs to high carbon alloy steel (carbon mass fraction is over 0.80%), Chromium is key element of alloy with mass fraction below 5% generally.
MATERIAL SPECIFICATIONS - EN ISO 4957: 2000 , DIN 17350 (1980)
PRODUCT DESCRIPTION
The alloy is usually produced by EAF /VD /LF /IFF followed by electroslag refining (ESR) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied bright (peeling or centreless grinding) in the softened = SA condition.
Final heat treatment - heat treatment / spheroidizing annealing
