Heat treatment Related

• Annealing of 34CrMo4 Alloy structural steel

heated to 870 ℃ and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. The 34CrMo4 alloy steel will get MAX 250 HB

• Hardening of DIN Alloy structural steel 34CrMo4

First quenching heated slowly to 880°C, Then after adequate soaking at this temperature quench in oil or water. Temper as soon as tools reach room temperature. Second quenching heat to 780-820°C, then quenching in oil or water.

• Tempering of 34CrMo4 Alloy structural steel

Heat to 205-649°C, then cool in water or oil. normal delivery hardness 18-22 HRC.

• Forging of Alloy Steel 34CrMo4

DIN 34CrMo4 alloy steel is forged at 926 to 1205°C (1700 to 2200°F)

Mechanical Properties of 34CrMo4 Alloy Steel

The mechanical properties of annealed DIN 34CrMo4 alloy steel are outlined in the table below

Applications of 34CrMo4

DIN 34CrMo4 steel Strength, high hardenability, toughness, and quenching small deformation, high strength and creep rupture strength at high temperatures. Requirements for the manufacture of higher intensity than the 35CrMo steel and tempered forging greater cross-section, such as a large locomotive traction gears, supercharger drive gear, pressure vessels, gear, rear axle, greatly affected by load and spring clip link It can also be used to 2000m deep oil drill pipe joints and fishing tools, and can be used bending machine mold, etc.
