Hot working in any but the annealed condition ams 6415 affect the strength level. It can be bent or formed by spinning or pressing in the annealed state.

AISI 4340 (E4340) per AMS 6415 – Bars (HR)

AISI is considered ams 6415 be a “through hardening” steel such that large section sizes can still be heat treated to high strength. The alloy may be cold worked, in the annealed condition, by conventional methods and tooling.

A full anneal may be done at F followed by controlled furnace cooling at a rate not faster than 50 F per hour down to F. It is known for its toughness and capability of developing high strength in the heat treated condition while retaining good ams 6415 strength. Not applicable to this alloy. From Ams 6415 it may be air cooled. Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required This material is stocked primarily in Bar Products by 59 distributors but is also available to a lesser extent in Flat Rolled Products, Forging Products, Tubular Products, Wire Products, Fasteners, Piping Components, and Ams 6415.


AISI is a heat ams 6415, low alloy steel containing nickel, chromium and molybdenum.

Forging may be done in the range of F max. The alloy will harden by cold working or by heat treatment — see “Heat Treatment” and “Tempering”. Machining is ams 6415 done ams 6415 this alloy in the annealed or normalized and tempered condition.

The temperature for tempering depends upon the strength level desired. It has good ductility.

Do NOT temper the alloy amz it is in the – ksi strength ams 6415 as tempering can result in degradation of impact resistance for ams 6415 level of strength.

For strength levels in the – ksi range temper at F. Typical applications are for structural use, such as aircraft landing gear, power transmission gears and shafts and other structural parts. Am radii should be 3t or greater. The alloy can be fusion or resistance welded.

For high strength over ksi ams 6415 alloy should first be normalized at F prior to heat treatment. It can be machined by all conventional methods. Mean Coeff Thermal Expansion.

Heat treatment for strengthening is done at F followed by an oil quench. Modulus of Elasticity Tension. See “Tempering” for strength levels.

Preheat and post heat weld procedures should be followed when welding ams 6415 alloy by established methods.

Consult the alloy supplier in regard to hot working. For strength in the – ksi range temper at F.
