Dec 18, 2019AISI 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 a lower tempering temperature. For example, a tensile strength of 225 ksi can be achieved by tempering at 316°C (600°F), and tensile strength of 130 ksi can be achieved by AISI 4340 816m 40 16511 45crnimoa Alloy Steel Bar(plate) EN24/ AISI 4340/ 40NiCrMo84 Alloy Steel Stockist AISI 4340 816m 40 16511 45crnimoa Alloy Steel Bar(steel) EN24/ AISI 4340/ 40NiCrMo84. EN24 steel is a medium carbon, low alloy steel known for its toughness and strength in generally large sections. EN24 is likewise one kind of nickel chromium molybdenum steels. It can be supplied hardened and tempered in the tensile range of 930-1080 Mpa as well as annealed condition.
