4340 Hot Rolled SBQ Bar. Hot rolled 4340 steel bar is a nickel-chromium-molybdenum medium carbon alloy steel that is known for its toughness. This steel grade also has good ductility and high strength. Hot rolled 4340 bar has good impact, and wear resistance in the hardened condition. 4340 Steel 36CrNiMo4 1.6511 EN24 SNCM439 - Otai AISI 4340 steel is a medium carbon, low alloy steel known for its toughness and strength in relatively large sections. AISI 4340 is also one kind of nickel chromium molybdenum steels. 4340 alloy steel is generally supplied hardened and tempered in the tensile range of 930 - 1080 Mpa. Pre hardened and tempered 4340 steels 4340 Steel Suppliers:Plate, Sheet Rickard Metals4340 alloy steel (also known as AISI 4340) is a low alloy steel with high toughness in an annealed state. 4340 alloy steel is characterized by its outstanding ductility, formability, and weldability rendering it an excellent metal for a variety of structural applications and components including power transmission gears and shafts, aircraft parts, and machinery. 4340 steel is mainly iron based

AISI 4340 Alloy Steel (UNS G43400) - AZoM

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. Tempering temperatures depend upon the desired strength level. Hardening. AISI 4340 alloy steel can be hardened by cold working or heat AISI 4340 Alloy Steel (UNS G43400) - AZoMAISI 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. Tempering temperatures depend upon the desired strength level. Hardening.

Characterised by high strength and toughness in relatively large sections.

AISI 4340 Steel - JIS SNCM439 - DIN 1.6563 - Songshun Steel

The properties and composition of 4340 steel round bar sheet plate as below. It is an alloy structural grade which used by the SAE International(SAE), and it is chrome-nickel low alloy steel. 4340 steel round bar sheet plate will get high tensile strength, hardness and toughness after heat treatment. Alloy Steel 4340 - Wingate Alloys IncTo 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. Atom Arc 4340 - ESABAtom Arc 4340 is an all-position, iron powder, low hydrogen electrode developed for the welding of heat-treatable, high strength steels such as SAE 4130, 4330, 4340 and steel castings with similar hardening properties. Weld metal responds to heat treatment similar to 4340 base metal and is intended for use only in postweld heat treated applications.
