1. EN36C Application
EN36C is a 3.50 % Nickel steel with Chromium & Molybdenum. It is a carburizing steel grade with very high surface strength with a soft but strong core. The material retains an incredible degree of toughness and fatigue resistance. EN36C can be used to make gear parts exposed to highest stresses and wear conditions. Typical components include gears, planet wheels, drive pinions, shafts, bushes and sleeves. Results in high core strength and excellent toughness in the components and is very suitable for parts with large diameter.

6.HEAT TREATMENT:
- Soft Annealing: Heat EN36C to 825oC, cool slowly. This will produce a maximum Brinell hardness of 217.
- Hardening: Harden from a temperature of 825-850oC, followed by oil or quenching.
- Tempering:– After carburising and hardening, the steel is tempered between 140°C and 200°C as required.
For use in the non carburised heat treated condition, temper in accordance with properties required.
7.Welding:
Pre-heat welding area to 250-450°C and maintain this temperature while welding with a low hydrogen electrode. Cool at a maximum rate of 100°C per hour. Do not weld after carburising.
8.Mill′s test certificate:
