Round EN 353 Carbon Steel Bars

Round EN 353 Carbon Steel Bars

Hardness:

HB - 270.

Heat treatment:

Most steel hardening treatments involve heating the steel to a set temperature and then rapidly cooling it by immersing it in oil or water. EN8 and EN353 steels are readily available and inexpensive materials suitable for heavy-duty applications.

Hardening:

Hardening °C 780-820.

Tempering:

EN353 is reheated to 780C -- 820°C, held until the entire section is uniform in temperature, and then quenched in oil, which must be tempered immediately while the EN353 assembly is still warm. Heat to 150C -- 200°C, soak for 1 -- 2 hours / 25mm slice, then cool in still air. Hardness after tempering: 62-64 HRC.

Forging performance:

The EN353 steel round bar offers a good combination of ductility, strength and wear resistance. EN353 is a very high strength alloy engineering steel.

Stress relief:

150-200, cool in the furnace.

First preheating °C: up to approx. 400 air circulation furnace

Second and third: 780 and 805°C.

Standardization:

860 -- 890 °C in air.

Annealing:

630-670 ° C
