Annealing AISI 4140 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling in the furnace. Tempering AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature. ALLOY Castle Metals SiteAlloy 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 Steels 4140 - Protolabs4140 may be forged at 2200 F down to 1700 F. Hot Working Hot working, if required, may be done in the range of 1900 F to 1500 F. Cold Working The alloy readily cold works in the annealed condition by conventional methods. Annealing Annealing is done at 1600 F followed by slow furnace cooling. Aging Not applicable to this alloy. Tempering

4140 may be forged at 2200 F down to 1700 F. Hot Working Hot working, if required, may be done in the range of 1900 F to 1500 F. Cold Working The alloy readily cold works in the annealed condition by conventional methods. Annealing Annealing is done at 1600 F followed by slow furnace cooling. Aging Not applicable to this alloy. Tempering Heat Treating Steel - Hardening and Tempering Annealing Non-Ferrous Material:Almost all non-ferrous metals are annealed by heating to somewhere just below the melting point and then cooling in air or by quenching in water. Quenching in water is a convienience. Alpha brasses (64-99% copper) are annealed by heating to 700 to 1400°F (the hotter the softer) and can then be be quenched. High Speed Steel D2 Steel D2 Technical DataD2 Tool Steel. D2 Tool Steel is a versatile high-carbon, high-chromium, air-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium-rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials. Although other steels with improved toughness or

Speedy Metals Information for 4140 Annealed Cold Roll Steel

4140 cold finished annealed is available in rounds, squares, rectangles and hexagons. 4140 cold rolled rounds is also available with an addition of .15-.35 lead (41L40), which improves machinability (77% of 1212, surface cutting speed 127 ft/min) without sacrificing other desirable properties, with the exception that the use of 41L40 is not Spheroidize Anneal Speaking of Precision BlogSolution annealing is referred to in commercial practice as LP Anneal or Lamellar Pearlite Anneal.Lamellar pearlite is the microstructure that predominates when doing this kind of anneal. The cycle for this anneal involves heating the material above the critical range (Ac3) and holding the steel (soaking) at that temperature for a length of time followed by slow cooling below the Spheroidize Anneal Speaking of Precision BlogSolution annealing is referred to in commercial practice as LP Anneal or Lamellar Pearlite Anneal.Lamellar pearlite is the microstructure that predominates when doing this kind of anneal.
