Heat treatment
Soft Annealing:
Heat to 640-680C, cool slowly in furnace. This will produce a maximum Brinell hardness of 310.
Normalizing:
Temperature: 850-880C, air.
Hardening:
Harden from a temperature of 840-870C followed by oil quenching.
Tempering:
Tempering temperature: 430-500C, air.
Test and inspection
Steel strip strength: Tensile strength; Elongation;Hardness
Steel strip testing: repeated bending test
Steel strip metallography: decarburization layer
Steel strip surface inspection: surface roughness
