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. ASTM A829 Alloy 4140 Steel Plate Leeco Steel, LLCLeeco Steel supplies A829-4140 Heavy Steel Plate, a structural quality, alloy-steel plate that can be supplied as rolled, annealed, normalized or normalized & tempered. Request a quote! Chemical Composition The following composition properties are ASTM specifications for A829 GR 4140. Datasheet 4340 ALLOY STEEL AMS 6414 VAR 4340 ALLOY STEEL AMS 6414 VAR UNSG43406 DATA SHEET GENERAL CHARACTERISTICS:4340 VAR AMS 6414 is a low alloy Chromium-Nickel-Molybdenum steel capable of being heat treated to high strength levels. This specification is for a premium aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.

Fabricating and Repairing 4130 and 4140 Steels in Heavy

Sep 22, 2018 · Both 4130 and 4140 have carbon, chromium (0.80 percent to 1.15 percent) and molybdenum (0.15 percent to 0.25 percent) as primary alloying elements. They differ slightly in their carbon content:4130 has a nominal 0.3 percent carbon, while 4140 has a nominal 0.4 percent. The strength of both materials can change greatly depending on the thermal treatment that has been Precision Ground Steel McMaster-Carr4140 Alloy Steel Rods Ready for turning in your lathe, these rods are precision ground and held to a strict straightness tolerance. SAE AISI 4340 Steel Properties, Heat Treatment, Equivalent SAE AISI 4340 Steel (UNS G43400) AISI 4340 steel (UNS G43400) is an ultra-high strength medium carbon low alloy steel, which combines deep hardenability, high ductility, toughness and strength, and has high fatigue resistance and creep resistance. It is not particularly affected by tempering and embrittlement, and exhibits good strength

Alloy Round 4140 Turned Grnd & Polished. 4142 HT TGP can be used for as wide variety of shafting applications where greater toughness and wear resistance is needed over lower carbon grades. This material roll threads, knurls, and may be plated.Handbook:Everything You Should Know About 4140 Steel4140 steel is annealed at 872°C which is equivalent to 1600°F. After that, the steel is cooled in a furnace. On the other hand, 4140 steel has tampered at the temperatures of between 200°C and 650°C. The temperature is adjusted depending on the desired level of hardness. There are various methods of hardening 4140 alloy steel.
