EN ISO 4957 Specification 60MnSiCr4 Round bar, Flat bar, Forgings 60MnSiCr4 Properties, hot forging, hot rolling, heat treatment, cold working.
MATERIAL DATA SHEET - TOOL STEEL DIN 60MnSiCr4
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

HEAT TREATTMENT PRACTICE
The preheating of measuring and cutting tool steel is spheroidizing annealing, final heat treatment is quenching + low temperature tempering and hardness after heat treatment can reach 60~65HRC. When heat treat tool steel grades consideration should be given to hardening temperature, including ratio of heating, cooling and soaking times which will differ due to factors such as the shape and size of each chemical component. Other considerations during heat treatment include the type of furnace, quenching medium and work piece transfer facilities.
