Sunny Xinrui 50 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 high wear resistance requirements, dynamic load and impact is not Parts, such as casting gears, drawbars, rollers, etc .; manufacturing relatively minor springs, digging plowing on agricultural machinery, heavy-duty mandrels and shafts, etc., and manufacturing of castings. Desong 50 carbon structural steel plasticity and toughness slightly worse, excellent cutting performance, weldability, hardenability in general, 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 50 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 the quenching is extremely important, the water critical diameter of 13 * 30mm, after tempering must be quenched to avoid the occurrence of temper brittleness. The steel cutting difficulties, the need for spheroidization to improve the chip properties of such carbon steel, in order to facilitate machining. 50 steel can be hardened to HRC42 ~ 46. So if you need the surface hardness, but also want to play 50 steel superior mechanical properties, often 50 steel surface carburizing quenching, so you can get the required surface hardness.
