Supply: 65 spring steel strip/plate, stainless steel strip, stainless steel plate.
Processing: Slitting, shearing, sanding (coiled strip, flat strip), polishing, straightening, pressing, electroplating, drawing.
Hardness: 45-48 HRC. Good performance.
The standard for 65Mn steel strip:
65mn spring steel strip execution standard: GB/T1222-2007
65Mn spring steel, manganese improves quenching penetrability, φ12mm steel can be quenched through oil, the surface carbonization tendency is smaller than that of silicon steel, the comprehensive mechanical properties after heat treatment are superior to those of carbon steel, but it has overheating sensitivity and temper brittleness. It is used for various flat and round springs of small size, seat cushion springs, spring springs, and can also be used to make spring rings, valve springs, clutch springs, brake springs and cold drawn steel wires cold rolled spiral springs.
The Rockwell hardness of 65Mn raw material:
1. Hot-rolled hardness: 240~270 HB
2. Cold-rolled soft state hardness: 190~220 HB
3. Cold rolled hardness: 300~340 HB
4. Heat treatment hardness: 38~60 HRC
65Mn Spring Steel Strip Specification:
Round Stock: Φ5.5~16mm Rolled Material: Φ16~160mm Forged Material: Φ160~450mm
The hardness, elasticity, and quenching penetrability of 65MN steel are all higher than those of 65 steel. 65MN steel is prone to heat sensitivity and annealing brittleness, and there is a tendency to form cracks during water quenching. The annealed state has moderate cuttability, low cold deformation plasticity, and poor weldability. It is suitable for medium-loaded plate springs, spring washers with diameters up to 7-20mm, and spiral springs. High wear-resistant parts, such as main shafts of grinding machines, spring retainer heads, precision machine tool screw rods, cutting blades, and ring sleeves on spiral roller bearings, and railway steel tracks.
