  • Other Analysis

Forging Properties:
Forging of SAE 1018 carbon steel can take place in the range of 996-1260°C (1825-2300°F).
Stress Relieving:
500°C – 700°C is required to relieve stress in AISI 1018 mild/low carbon steel that is later cooled down in still air.
AISI 1018 mild/low carbon steel should be heated at 890°C – 940°C and then cooled in still air.
Complete annealing of this alloy can be achieved by soaking at 899°C (1650°F) followed by furnace cooling. Process annealing can be done at 649°C (1200°F)
