40HNMA, 40NiCrMo7, AISI 4340 - Destination and specification. Structural alloy steel with very good strength properties and particularly high hardening properties, used for thermal improvement on highly stressed machine parts exposed to impact, twisting and vibration, where suitable impact strength is
4340 is a 1.8% nickel - chromium - molybdenum high hardenability high tensile steel - generally supplied hardened and tempered in the tensile range of 930 - 1080 Mpa (condition U) - (Rc 28 - 36).. Characterised by high strength and toughness in relatively large sections. Pre hardened and tempered 4340 can be further surface hardened by flame or induction hardening and by nitriding. AISI 4140 Alloy Steel - Waldun SteelWALDUN is one of the best AISI 4140 alloy steel Manufacturer and Exporter from China. You can get round,square,flat,block,and shaft etc. AISI 4140 alloy steel is defined as a low alloy steel which has 1% Cr-Mo as strengthening alloy elements.Compared with AISI 4130, it has a higher carbon content with good balance of strength, toughness ,abrasion and impact resistance and heat treatment capabilities,but poor in weldability characteristics.AISI
Under the standardization AISI 4340, we understand the following material grades in the German material system:1.6511 - 36CrNiMo4 1.6565 - 36CrNiMo4 1.6580 - 30crnimo8 1.6582 - 34CrNiMo6. The materials that can be assigned to the AISI 4340 are low alloy, medium carbon steels known for their toughness and strength. AISI 4340 High Tensile Steel Hardened Steel 4340 Alloy Steel.

AISI 4340 is a medium carbon, low alloy steel containing chromium, nickel and molybdenum. It has high toughness and strength in the heat-treated condition. The 4340 steel have good shock and impact resistance as well as wear and abrasion resistance in the hardened condition. Tool steels:AISI classification steel-guidefoAmerican tool steels (AISI) The letter "L" went to this series from the word "low" all of these steels are low alloy and similar to conventional low alloy steels. for instance, essentially L6 steel is very close to steel 4340 with carbon content from 0,4 to 0,7 %.
