    We are 100CR6 Alloy steel stockists, stockholders, exporters, and suppliers from India. 100CR6 Alloy steel is a medium carbon steel with moderate tensile strength. While the material is capable of through hardening by Quenching and Tempering on limited sections, it is more commonly supplied untreated or normalised.

    For rolling contact and other high fatigue applications, DIN 100Cr6 is a through hardening bearing steel. Hardened steel has the right properties to withstand high cycle, high stress fatigue because of its high hardness, strength, and cleanliness. 100Cr6 is mainly used for small and medium sized bearing components. It is also regularly used for other machine components that require high tensile strength and high hardness. DIN 100Cr6 bearing steel is a high quality Alloy Bearing steel, It belongs to the High Quality, High Carbon, Alloy Chromium, Manganese Steel.

    The 100CR6 alloy steel specification is a Chromium, Manganese alloy steel. AISI 52100 and GB GCr15 are equivalent to 100Cr6. For bearings and roller balls, 100CR6 alloy steel is the most commonly used steel. A good hardenability, diameters up to 30 mm, good inalterability, excellent wear resistance at hardened and stress relieved states, and good machinability with machine tools are all characteristics of this steel that make it ideal for roller balls. Rolls for bearings of small and medium dimensions, ring nuts, balls and small rollers for cold rolling, spindles and cams for textile machinery can be made out of it.

    The most common material used to make precision ball bearings, roller bearings, and tapered roller bearings is 100Cr6 chrome steel. These components are the bearings inner and outer rings, balls and rollers. The chemical composition of this steel has high carbon and about 1.5% chromium content. Using controlled processing and heat-treating methods the finished bearing components have

    high strength to resist cracking and a hard surface to resist subsurface rolling contact fatigue. 100Cr6 is a Chromium containing low alloy steel that is through hardening and noted in particular for use as bearings.

    100CR6 Alloy steel Heat Treatment

    Partial Annealing

    Make the temperature up to 770-790°C, then cool the furnace to 550°C after thermal retardation, and then air cool the stove. Hardness requirements are 187-229HBS.

    Isothermal Spheroidizing Annealing

    First of all, heat it to get 770-790℃, after being isothermal at 680 ~ 700 ℃, it will be cooled with the furnace to below 550 ℃ and then air-cooled. The hardness of 100Cr6 steel must be 187-229HBS.

    Stress Relieving

    The furnace should be heated up to 600-700°C, then kept at that temperature, and then cooled. Mould steel should have a hardness of 187-229HBS. Characters remove residual stress and work hardening.

    Normalising

    Heat it until the temperature is at the range of 930-950℃, maintain the temperature, air cooling. The hardness needs to be 302-388HBS.

    Tempering

    Heat to 150-190℃, stay the temperature for 2 hours, and furnace cooling. The hardness is 58-62HRC.

    Quenching and Tempering

    840-860°C for quenching, oil cooling, 660-680°C for tempering, furnace cooling or air cooling after heat preservation. A hardness of 197-217HBS is required. By high-temperature quenching, defects in the carbide structure can be eliminated, and by high-temperature tempering, the sorbite structure can be prepared for re-quenching. Increase toughness while increasing strength, then quench, heating temperature 820 °C – 840 °C, oil cooling.

Increase toughness while increasing strength, then quench, heating temperature 820 °C – 840 °C, oil cooling.
