AISI 4340 Heat Treatment. AISI 4340 alloy steel is heat treated at 830°C (1525°F) followed by quenching in oil. AISI 4340 Forging. AISI 4340 alloy steel is forged at 427 to 1233°C (1800 to 2250°F). AISI 4340 Cold Working. AISI 4340 alloy steel can be cold worked using all conventional methods in the annealed condition. It has high ductility 4340 Steel 36CrNiMo4 1.6511 EN24 SNCM439 - Otai AISI 4340 steel is a medium carbon, low alloy steel. Otai steel is one leading supplier of 4340 steel & equivalents:36CrNiMo4, 1.6511, EN24, SNCM439 etc.
AISI 4340 steel stockholders and suppliers, delivering to the whole of the UK. AISI 4340 is a nickel chromium molybdenum alloy steel specification widely used in the oil and gas sectors. As a quality grade alloy steel it offers toughness and high strength in the heat treated condition, with good fatigue strength. 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 hardened by flame or induction AISI Alloy Steel 4340Hardening. This heat treatment results in the formation of martensite after quenching, resulting in increased hardness and tensile strength. A temperature range of 1500 1550 º F (815 845 º C) is the normal austenitizing temperature for direct hardening of 4340 grade. Oil quenching is normally used for 4340 as the alloys
1.65-2.00. 0.20-0.30. Alloy E 4340 is a widely used deep-hardening constructional steel. Due to E-4340's high alloy content it obtains a uniformed hardness by heat treatment. The high fatigue strength makes E4340 ideal for highly stress parts as it maintains 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.
