Heat treatment Related

  • Annealing of EN3 Carbon structural steel

EN3 is commonly supplied bright drawn or as rolled. If annealing is required heat to 880-910°C, furnace cool. The EN3 carbon steel will get MAX 250 HB （Brinell hardness）.

  • Hardening of EN3 Carbon structural steel

Heated slowly to 880-910°C, Then after adequate soaking at this temperature quench in water and temper.. Temper as soon as tools reach room temperature.

  • Forged of EN3 Carbon structural steel

Forged at forged temperature, normal hot rolled is ok.

Mechanical Properties

The mechanical properties of annealed DIN W N-R EN3 carbon steel are outlined in the table below

(1) phase transition temperature (approximate) Ac1 = 735 ℃, Ac3 = 855 ℃, Ar3 = 835 ℃, Ar1 = 680 ℃

(2) Specification normalizing temperature 920 ~ 950 ℃, cooled baked. The hardness of 131 ~ 156HBS.

(3) Specification softening rough cold temperature 700 ~ 720 ℃, holding time of 8 ~ 15h, and then to 50 ~ 100 ℃ / h cooling rate, the furnace temperature dropped to ≤550 ~ 600 ℃, cooled baked.

Before treatment hardness ≤143HBS, soften hardness ≤131HBS.

(4) specification quenching temperature 910 ℃ ± 10 ℃, 10% NaCl brine cooling.

(5) the measured yield strength fy = 245Mpa, the modulus of elasticity E = 206Gpa, Poisson’s ratio ν = 0.3.

(6) shear strength of 275 ~ 392MPa, a tensile strength of 253 ~ 500MPa, yield strength of 275MPa, elongation of 25%.
