Detailed Information

Manufacturer & Supplier of AISI 3310/EN36 Alloy Steel in Mumbai, India

According to the BS970 standard, EN36 case hardened steel is split into three types: EN36A, EN36B, and EN36C, all of which are Ni-Cr-Mo alloy steels.

EN36 series steels are case hardening of steel, with a high surface hardness, high strength, and a soft core without sacrificing strength. To achieve high strength and hardness, EN36 series steel can also be quenched and tempered.

EN36 steel is commonly used in mechanical engineering to make mechanical parts with high wear resistance, such as gears, screws, shafts, rollers, and so on. It’s also employed in aviation engineering, shipbuilding, the railway sector, the oil industry, and a variety of other fields.

FORGING OF EN36 STEEL

  • Initial Forging Temperature:1180-1200℃
  • Final Forging Temperature:800-850℃
  • Heating Rate:Strictly control the heating speed, which should be uniform and stable to prevent cracking caused by improper heating.
  • Holding Time:Ensure that the material is fully and evenly heated,and the holding time should not be too long or too short.
  • Forging Ratio:above 4:1
  • Post-Forging Treatment:EN36 steel must be annealed after forging.

HEAT TREATMENT OF STEEL EN36

EN36 Steel Conventional Heat Treatment Temperature Selection
  • Annealing:830 – 850°C, Cooling in a furnace, hardness below 229 HBW
