Product name: spring steel 65Mn 

 Supply specifications: 

 Thickness of 4.5mm-100mm, width 1500mm-4020mm, length 3000mm-18000mm, the largest single steel weighing 25 tons. Can also be negotiated custom processing non-standard goods cut to length steel plate. 

 Origin: Anshan Iron and Steel, Wuyang Iron and Steel, Wuhan Iron and Steel, Baosteel, the new steel and other 

 Steel surface hardness: 

 Hot-rolled: ≤ 302HB; heat cold LAC: ≤ 321HB 

 The direction of the flaw detection and thickness of the performance: 

 Can produce additional testing requirements and Z15-Z35 tear-resistant steel plate (thickness direction performance), in accordance with standards such as ASTM, A770 steel plate Z to performance. 

 Chemical composition (%): 

 C :0.62-0 .70; si :0.17-0 .37; Mn :0.90-1 .20; Cr: ≤ 0.25; Ni: ≤ 0.25P: ≤ 0.035; S: ≤ 0.035; Cu: ≤ 0.25. 

 Uses and characteristics: 

 Manganese increase hardenability, 12mm diameter steel hardenability, surface decarburization tendency smaller than silicon, the mechanical properties after heat treatment is better than carbon steel, but overheating sensitivity and temper brittleness. Used for a variety of flat, small size, round spring, cushion spring, spring spring spring ring can also be produced, valve springs, clutch springs, brake springs, cold rolled and cold drawn steel wire coil spring. 

 Delivery status: 

 Normalizing and tempering, tempering, debugging, controlled rolling and cooling 

 The 65mn strength. Hardness. High flexibility and hardenability than 65 steel, with a thermal sensitivity and tendency to temper brittleness, water quenching the formation of cracks tendency. Annealed machinability can still be cold deformation plasticity, poor weldability. Under moderate load plate spring, diameter 7-20mm
