4.Heat Treatment for 4140 steel round bars
4140 alloy steel material is a high quality Quenched and Tempered Alloy Structural steel, It belong to the high quality medium carbon alloy steel, Oil Quenched & Tempered Hardenss is 28-34 HRC.4140 Annealing delivery hardenss less than 250HB

Heat treatment of aisi 4140 steel 
Annealing
AISI 4140 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling in the furnace.
Tempering
AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature
Hardening
AISI 4140 alloy steel can be hardened by cold working, or heating and quenching.
