6. 4140 alloy steel Heat treatment. 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.
4140 HIGH TENSILE STEEL 4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T).4140 is now available with improved 4140HW Alloy Steel Technical Data4140HW Alloy Steel Technical Data You find 4140HW in a variety of bar and tubing applications in quenched and tempered conditions.
