ASTM A829 & 4140 STEEL PLATE

Alloy Plate - 4140 / 4340 / 8620 - ASTM A 829
Standard specification for Alloy Steel Plate Furnished to Chemical Composition Requirements

ASTM A829 was first issued in 1984 prior to that these grades were defined by AISI specifications.

This specification covers structural quality alloy steel plates furnished to chemical composition requirements only. There are no tensile requirements or other mechanical property requirements for this specification.

The ASTM A 829 specification covers 30 standard chemistries. Radisson Impex offers these chemistry-only alloy plate grades in the three most commonly used chemistries. 4140 is the standard for medium carbon chromium-molybdenum alloy with excellent response to quench-and-temper and moderate through hardening capabilities; at Radisson Impex, our 4140 is modified to include a small amount of vanadium for even better hardening. 4340 includes nickel for higher overall hardness and superb through hardening. 8620 is alloyed for as-rolled core strength but can be readily carburized.

A829-4140 steel plate is a structural-quality, alloy-steel plate that can be supplied in the following conditions: as rolled, annealed, normalized, and normalized and tempered. A829-4140 can be used for a wide variety of applications where greater toughness and wear resistance is needed over lower carbon grades.

The list for uses of A829-4140 is long and includes: strippers, holder blocks, mold bases, ejectors, forming dies, back-up and support tooling, fixtures, stubs, couplings, reamer bodies, tie rods, gears, gear racks, valves, chain links, jigs, spindles, sprockets, tool bodies, tool holders, guides, tracks, ways, slides, wear strips or parts, molds, brake dies, trim dies, bolsters, machinery parts and components.

General requirements for delivery
Material shall conform to the requirements of ASTM A 6.

Tensile Requirements
There are no mechanical property requirements for these grades. Generally, the alloy content provides the potential for these steels to achieve certain mechanical properties when they are subjected to the appropriate thermal treatment process. This is usually performed after flamecutting or sawcutting, and is done to achieve the specific properties required by the end-use application. Radisson Impex provides a complete range of thermal treatment process options.

Forging

Preheat the steel carefully, heat to 1150 oC – 1200 oC maximum, hold until temperature is uniform throughout the section.
Do not forge below 850 oC.Following forging operation the work piece should be cooled as slowly as possible.

AISI 4140 Steel Grade Heat Treatment

Annealing
Heat ASTM 4140 steels to 800 oC – 850 oC, hold until temperature is uniform throughout the section and cool in furnace.
Normalizing
Heat steel alloy 4140 to 870 oC – 900 oC, hold until temperature is uniform throughout the section, soak for 10 – 15 minutes and cool in still air.
Tempering
Re-heat 4140 grade steel to 550 oC – 700 oC as required, hold until temperature is uniform throughout the section, soak for 1 hour per 25 mm of section, and cool in still air.

Hardening of AISI Alloy Steel 4140

AISI alloy 4140 steel bar, plate and square can be hardened by cold working, or heating and quenching.

SAE 4140 alloy steel is usually supplied ready heat treated to hardness in 18-22 HRC. If further heat treatment is required, then heat to 840 oC – 875 oC, hold until temperature is uniform throughout the section, soak for 10 – 15 minutes per 25 mm section, and quench in oil, water, or polymer as required.

Application of AISI alloy round 4140 steel Plates

ASTM alloy 4140 steel bar, flat or plate material can be used for as wide variety of applications where greater toughness and wear resistance is needed over lower carbon grades. Typical applications for 4140 tool steel uses include Components, Adapters, Arbors,strippers, holder blocks, mold bases, ejectors, back up and support tooling, fixtures, jigs, molds, cams, drill collars, Axle Shafts, Bolts, Crankshafts,stubs, couplings, reamer bodies, axles, shafting, piston rods, rams, hydraulic machinery shafts, gears, sprockets, gear racks, chain links, spindles, tool bodies, tool holders, tie rods, Connection Rods, Chuck Bodies, Collets, Conveyor Pins & Rolls, Ejector Pins, Forks, Gears, Guide Rods, Hydraulic Shafts & Parts,Lathe Spindles, Logging Parts, Milling Spindles, Motor Shafts, Nuts, Pinch Bars, Pinions, Pump Shafts,boring bars,tracks, slides, wear strips or parts, forming dies, brake dies, trim dies, bolsters, machinery parts and components, etc.

Alloy 4140 (AISI 4140) is one of the most popular direct hardening Cr-Mo alloy steel plates that have the ability to develop an extensive range of hardness and strength. Alloying elements and thermal treatments, such as quenching and tempering, greatly influence the hardness and strength of the steel.

Alloy 4140 plate is widely used for general purpose industrial machining. Welding and forming of this steel plate should be avoided. It is best utilized wherever high resistance to fatigue and or impact is necessary.
