Hardened - Import export

Introduction: 303 through  hardened screw, has better corrosion resistance  Tail annealing treatment, greatly improving the toughness of the screw CNC full grinding thread, tooth root top concentric and tooth bottom flatness high precision, can reduce the shear heat. Application: Low acid plastic + GF15 following, such as PMMA, PC and so on Temperature ≤400 ℃ Optical lenses, cosmetic packaging and so on Materials and Process: Material origin: Japan The main components: Cr, V, Mo and so on Heat treatment: vacuum quenching, hardness HRC48-52. (1020-1050 vacuum quenching, high temperature tempering 550-570 more than three times, the rear high temperature annealing softening treatment) Surface treatment: PVD coating (TiN, TiCN, TiAlTiN)

Ming Xiao Manufacturing Co., Ltd is specialize in custom machine parts more than 20 years, we have various automatic lathe turning machines can produce small turned parts, especially produce steel pins with low cost and high speed. We have can do further machining and treatments for steel pins, such as milling, grinding, drilling & hardening treatments. Common materials for pins are 35 or 45 steel. The material of the safety pin is 35, 45, 50, T8A, T10A, etc., and the hardness after heat treatment is 30~36HRC. The pin sleeve material can be 45, 35SiMn, 40Cr, etc., and the hardness after heat treatment is 40~50HRC. Pins play a pivotal role in the connection of mechanical components. According to different shapes and functions, it can be divided into: split pin, tapered pin, cylindrical pin, grooved pin, dowel pins,coupling pins, etc. Among the pin products, cylindrical pins, tapered pins and split pins are commodity fasteners that are produced.
