4340 AISI 4340 SAE 4340 Alloy Steel - SAE AISI 1010 1015

4340 - Highly alloyed steel, nominally 1.8% Ni, .80% chromium and .25% molybdenum. High strength characteristics. Used for heavily stressed parts operating in fatigue and other duty conditions. AISI 4340 has a favorable response to heat treatment usually oil quenching followed by tempering and exhibits a good combination of ductility and strength when treated thusly.

The time dependent deformation due to heavy load over time is known as creep. Strength of Steels - Tensile Strength of SteelsSteels consist of iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type). Adding a small amount of non-metallic carbon to iron trades its great ductility for the greater strength.Due to its very-high strength, but still substantial toughness, and its ability to be greatly altered by heat treatment, steel is one of the most useful and common ferrous alloy in modern use.

[64] WELDING HIGH STRENGTH STEELS Fabricating and If a welder is welding high strength steels to each other, then typically the filler metal will match the yield strength of the two. For example, welding high strength steel with 100 ksi yield strength to itself would require a filler metal that offers a minimum of 90 ksi tensile strength (and a maximum of 120 to 130 ksi). 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.
