55 carbon steel
Sunny Xinrui 55 carbon structural steel is a high-strength medium carbon steel, the industry also known as steel, after treatment has a high surface hardness and strength, for the manufacture of connecting rods, rollers, gears, flat springs, wheels, wheels Edge, etc., can also be used for casting. 55 carbon structural steel plasticity and toughness slightly worse, excellent cutting performance, weldability, hardenability generally water quenching with the tendency to form cracks. Generally used in normalizing or quenching is better, mainly used for demanding high strength and wear resistance or elasticity, dynamic load and impact load is not large parts, such as gears, rims, flat springs, crankshaft and so on.
Sunny Xinrui 55 steel is made by the level furnace or pure oxygen converter steelmaking made of the whole static steel, with excellent processing, uniform organization characteristics, cheap, easy processing, suitable for high-frequency quenching, flame quenching and other surface hardening deal with. The steel has a carbon content of 0.40, excellent wear resistance, reduced ductility, quenching and deformation and cracking, so quenching is extremely important, and the tempering must be quenched to avoid the occurrence of temper brittleness. The steel cutting difficulties, the need for ball treatment to improve the chip performance of such carbon steel, in principle, tempering to the hardness of 19-22HRC, in order to facilitate machining.
