4140 steel spec sheet. This page is mainly introduced the astm 4140 datasheet including chemical information mechanical properties physical properties mechanical properties heat treatment and micro structure etc. Physical properties mechanical properties heat treatment and micro structure. Stainless steel special steel compressor blading turbine blading superalloy supplier. 4140 annealed is designated as 4140 ann or simply 4140.

This is one of the chromium molybdenum manganese low alloy steels noted for toughness good torsional strength and good fatigue strength. For example a tensile strength of 225 ksi can be achieved by tempering at 316 c 600 f and tensile strength of 130 ksi can be achieved by tempering at 538 c 1000 f. Aisi 4140 alloy steel can be tempered at 205 to 649 c 400 to 1200 f depending upon the desired hardness level. It also contains the use of astm 4140 such as it is commonly used in bars sheet plates steel coils steel pipes forged and other materials application.

4140 high tensile steel. 4140 annealed is supplied in the soft condition and can be hardened to rc 54. The following specifications cover alloy steels 4140. Aisi 4140 steel bar steel plate flats supplier stockist and exporter.

4140 alloy steel data sheet. Sae 4140 can be supplied as steel plate sheet round steel bar steel tube pipe steel stripe steel billet steel ingot steel wire rods. 4140 ht is supplied in many forms such. 4140 is an alloy steel that is supplied in either the annealed or prehardened condition.

Machinability which greatly increases feeds and or speeds while also extending tool life without adversley affecting. 4140 download 4140 spec sheet. Hardened and tempered in the tensile range of 850 1000 mpa condition t 4140 is now available with improved. These alloys have good ductility but are tougher than plain carbon steel and thus usually require more force or pressure for forming.

Astm a193 grade b7 specification for high tensile bolts screws stud bolts threaded rods anchor bolts and other externally threaded fasteners made from heat treated chromium molybdenum alloy steel grades such as 4140 4142 4145 4140h 4142h and 4145h in sae aisi classification. The prehardened condition is heat treated to a medium hardness hrc 28 32 and is designated as 4140 ht. The hardness of the steel can be increased if it has a lower tempering temperature. Astm a193 specification covers requirements for chemical composition mechanical properties hardness heat.

Aisi sae 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components like axles shafts bolts gears and other applications. Similar to alloy grade aisi 4130 chrome moly alloy steel but with a slightly higher.
