Material: SUS316L Density: ≥ 7.8g/cm3 Hardness: ≥ 120 HV10 Tensile strength: ≥500mpa Yield strength: ≥180mpa Elongation: ≥50% ? Feature：The lock cylinder is the heart part of the door lock. Even if it is a smart lock,Website:http://www.no2-machinery.com, the safety level of the lock cylinder is still very important. Its main function is to transfer the torsion from the head, so as to drive other parts to open and lock. The head structures of padlocks, drawer locks, door locks and bicycle locks are different, and the ways of transmitting torsion are different, but the functions are the same. Advantage: MIM is the best way to make a lock cylinder. Not only MIM can make various kinds of complex shape parts, but also it can meet the requirements of the size precision. If the tolerance has high demand, after MIM, we need to do extra CNC process. As to the surface, most lock parts have no f......url:http://www.no2-machinery.com
