7: DIN 1.3505 Steel Application

 1.3505 steel is widely used in various applications of rotating machinery bearings. Typical applications such as valve bodies, pumps and fittings, high loads on wheels, bolts, studs, gears, internal combustion engines. Steel balls, rollers and shaft sleeves on transmission shafts of electric locomotives, machine tools, tractors, rolling equipment, roadheaders, railway vehicles and mining machinery.


8: DIN 1.3505 Steel Heat Treatment

Annealing : Slowly heat to 872° C (1600° F) and then slowly cool to reduce cold working or machining stresses. Different annealing methods will give different hardness. 1.3505 Bearing steel will obtain hardness MAX 248 HB.

Quenching : Heat slowly to 816° C (1500° F) and quench in oil to obtain a hardness of 62 – 66 HRc. 

High temperature tempering: 650-700℃, air cooled, hardness 22-30HRC. 

Low temperature tempering: 150-170℃, hardness: 61-66 HRC.
