Use the following information as a guide to check your drawing. These tips will help assure proper heat treating and annealing. Case Hardening. On low carbon steel parts (1213, 12L14, 1117, 8620, etc.) specify case depth and hardness that is required. Heat Treatments:Softening:AnnealingProcess Annealing:Process Annealing is used to treat work-hardened parts made out of low-Carbon steels (< 0.25% Carbon). This allows the parts to be soft enough to undergo further cold working without fracturing. Process annealing is done by raising the temperature to just below the Ferrite-Austenite region, line A 1 on the diagram. This temperature is about 727 ºC (1341 ºF) so heating it

Polymer quenching is useful for a wide range of steels. From AISI 1045 to AISI 4340 the polymer quenching hardening heat treatment can be the solution for complex jobs. If quench uniformity is required, such as in complying with the Caterpillar 1E0106A or 1E0106B specification, polymer quenching is an excellent choice. Table of Steel Equivalent Grades (EN, SAE/AISI, UNS, DIN Jul 24, 2010 · Table of Steel Equivalent Grades (EN, SAE/AISI, UNS, DIN, BS, UNI, JIS) The table below compares steel equivalent grades of materials from various international specifications. Note that materials compared are the nearest available grade and may have slight variations in actual chemistry. Tempering of Steel:Stages and Classification Heat Tempered plain carbon steels (0.6 to 1.3% C) have a hardness of R c 58 to 63. This treatment is given normally to tools of plain carbon and low alloy steels, where the main properties to be developed are high cutting-ability, wear and abrasion resistance with some toughness.
Overview Also called "stressproof", this alloy has excellent strength and hardness, and is specifically treated to relieve stresses in the metal created during the manufacturing process. This means that the bar is less prone to warping after it is machined or heat treated. Further, 1144 is easily machined. cold-roll-steel 1144 Product Guide from Online MetalsThis means that the bar is less prone to warping after it is machined or heat treated. Further, 1144 is easily machined.

Steel is the common name for a large family of iron alloys. Steels can either be cast directly to shape, or into ingots which are reheated and hot worked into a wrought shape by forging, extrusion, rolling, or other processes.
Dec 21, 2004 · RE:Heat treating AISI 1144 for best wear resistance. TVP (Materials) 21 Dec 04 09:47 Be aware that this grade will be quite susceptible to quench cracking when water quenched, so if the tool has sharp corners or drastic changes in section, then this may pose a problem.Im certainly no expert. But I HAVE heard about hot oil (somewhere around 100 degrees F) for crack-prone alloys. Im guessing the search bar yieldedYa, my google-fu didn't come up with any good info for 1144. There are plenty of examples of people using it for hammers but at the same time someYou might want to consider not heat treating the hammer. It's easier to re-face the hammer than the surface of the anvil. DougThanks for the reply Doug! If I don't HT, would some grain refining normalizations be a good idea? I've read the grain on 1144 is kept rather largeJared, I found the above here (there are buttons at the bottom of the page for specific alloys.) More can be found about the affects of sulfur in sWith that in mind, might I recomment machining a hammer head out of it?Thanks for all the input. I think I'll give it a try without the HT and see what happens. If it doesn't stand up to forge work I can always reface ASTM SAE AISI 1045 Carbon Steel Heat Treatment, Chemical SAE AISI 1045 Steel. ASTM SAE AISI 1045 steel is one of the commonly used medium carbon steels with an average carbon content of 0.45%, medium tensile properties, good strength, toughness and wear resistance. It can be treated by annealing, flame treatment or induction hardening.
