S45c Heat Treatment Furnace

1. s45C Features

The steel has a carbon content of more than 0.4% and has excellent wear resistance, but its ductility is reduced, and it is easy to deform and crack during quenching. Therefore, heat treatment is extremely important, and it must be quenched after tempering to avoid temper brittleness. By spheroidizing the steel, the cutting performance of this type of carbon steel can be improved. 45C is widely used in mechanical manufacturing, and the mechanical properties of this steel are very good. But this is a medium carbon steel, and its quenching performance is not good. No. 45 steel can be quenched to HRC42~46.

3. S45C Heat Treatment Furnace

Quenching Furnace: Quenching temperature 840+10℃, water cooling (55 58HRC, limit 62HRC):

Tempering Furnace: The tempering temperature is 600±10℃, and the furnace is air-cooled (20~30HRC).

Hardness: 20~30HRC

Uses: It is commonly used in molds to make No. 45 steel pipe templates, tips, guide posts, etc., but after heat treatment and tempering treatment, the parts have good comprehensive mechanical properties and are widely used in various important structural parts.Especially those connecting rods, bolts, gears and shafts that work under alternating loads.But the surface hardness is low and it is not wear-resistant. Can be quenched and tempered + surface quenching to improve the surface hardness of the parts), the highest hardness in practical application is HRC55 (high-frequency quenching HRC58).
