Introduction:

Professional manufacturer of asphalt machines. Our sales and R&D team have over 10 years’ experience to focus on asphalt distributor, synchronous pavement surface vehicles and other road machinery and equipment. Based on innovation

Quality Standard:

DIN 17230-1980 Ball and Roller Bearing Steels

All Grades Comparison:

Material No. 1.3520; EN 100CrMn6

Chemical Composition(%):

Heat treatment:

l NORMALIZING: Normalizing temperature: 860-900℃.

l SOFT ANNEALING: Heat to 760-800℃, cool slowly in furnace. This will produce a maximum Brinell hardness of 217.

l STRESS RELIEVING: Stress relieving to remove machining stresses should be carried out by heating to approx. 650℃, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

l HARDENING: Harden from a temperature of 830-890℃ followed by oil quenching. Hardness after quenching is approx. 64 HRC.

l TEMPERING: Tempering temperature: 150-180℃.
