AISI 1116 Heat Treatment
Annealing – Full anneal – Austenitize (heat to critical temperature) – Quench in oil – Tempering as required. Hardening – Harden from a temperature of 1550º F (843º C) followed by water quench or air cool. Tempering – Temper immediately after quenching. Reheating should be between 1150º F – 1200º F (620º C – 650º C.) For maximum hardness and strength, temper between 400º F – 600º F (200º C – 315º C.)
AISI 1116 Machining
When annealed, this steel can be machined easily using standard methods. However, when hardened, it becomes more difficult to machine due to the high hardness.
AISI 1116 Welding
This steel can be welded using any standard welding method. Preheating is not necessary before welding. However, post-weld heat treatment may be necessary to achieve the desired mechanical properties.
AISI 1116 Corrosion resistance
SAE/AISI 1116 steel offers excellent corrosion resistance in many different environments. This resilience is the result of its low carbon and sulfur content, which increases the steel’s resistance to pitting.
