4340 (E4340) Alloy Steel, AISI 4340, Plate, Round Bar AQ AISI 4340 (E4340) alloy steel is a medium carbon, low alloy steel known for its toughness and strength. Machining is done typically in the annealed condition. 4340 steel properties offer good ductility in the annealed condition, allowing it to be bent or formed. Fusion and resistance welding is also possible with our 4340 steel from stock.

A8 ground bar can also be supplied, providing a high quality tool steel precision ground tool steel bar to your required tolerances. AISI A8 steel is also available as Ground Flat Stock / Gauge Plate, in standard and nonstandard sizes.
7 Things To Consider When Choosing An Alloy Steel Grade Nov 24, 2016 · Heating and quenching alloy steels such as AISI 4340 and AISI 6150 can result in very high tensile strengths and hardnesses throughout the thickness of the material when compared with low carbon steel. AISI 8620 is a steel that is commonly carburized which is a form of case hardening.
AISI 4140 Alloy Steel (UNS G41400) - AZoMAISI 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 steel can also be produced as light plates and castings.
AISI 4340 Alloy Steel (UNS G43400) - AZoMAISI 4340 alloy steel can be cold worked using all conventional methods in the annealed condition. It has high ductility. Annealing. AISI 4340 alloy steel is annealed at 844°C (1550°F) followed by cooling the furnace. Tempering. AISI 4340 alloy steel should be in the heat treated or normalized and heat treated condition before tempering.
4340 Steel Heat Treatment. AISI 4340 alloy steel is heat treated at 830°C (1525°F) followed by quenching in oil. Flame or Induction Hardening. As mentioned above, pre-hardened and tempered 4340 steel bars or plates can be further surface hardened by either the flame or induction hardening methods resulting in a case hardness in excess of Rc 50.
AISI 4340 Steel 36CrNiMo4 1.6511 EN24 817M40 Short Description:AISI 4340 steel is a medium carbon, low alloy steel known for its toughness andstrength in relatively large sections. AISI 4340 is also one kind ofnickel chromium molybdenum steels. 4340 alloy steel is generallysupplied hardened and tempered in the tensile range of 930 1080 Mpa.Pre hardened and tempered 4340 steels can be further surface

To achieve 125 - 200 KSI tensile strength, temper at 950° F. Do NOT temper 4340 material in the 220 - 260 KSI tensile strength range (tempering can result in degradation of impact resistance). Other Comments. AISI 4340 is considered a "through hardening" steel, such that large section sizes can be heat treated to high strength.
Alloy Steel 4340 Metal Supermarkets - Steel, Aluminum Grade Summary:This steel can obtain much deeper harden-ability than 4100 series steel. High strength in heavy sections is possible with maximum toughness and ductility. This material has a high fatigue/tensile ratio and maintains strength, ductility, and toughness at relatively high temperatures. Also has excellent non-distorting properties for an alloy steel.
