Nov 23, 2007 · Hi, Im new here, but I have "some" experience in heat treating steel, We used to HT springs, one day we were HT'in a large spring for a homebuilt aircraft, for the landing gear. of course this is a quick discription of how we did it, and of course ht is a craft of metalurgists, I am not.
Heat Treating 5160 BladeForumsApr 20, 2017 · I've just gotten started on my first knife project, and I settled on 5160 steel. I just wanted to know the best method of heat treating. I've seen a bunch of different answers pop up all over the place--I read that Bob Loveless used a propane torch, but other people talk about how they had to set up forges.
Apr 20, 2017 · We need to "reset" the steel, so to speak, when coming from a leaf spring especially. That way we know exactly what we're working with going into the hardening/quench. Normalizing by definition is done only once, and is at 1600°F for this particular alloy. I would say soak at this temp for a few minutes, if you can with your forge.
Heat Treating Steel - Hardening and Tempering A dry ice acetone bath typicaly provides -78°F (-61°C) which is far short of the cryogenic temperature needed for treating steel. Not all steels are improved by cryogenic treatment. It is also part of a complete heat treatment not a replacement or simple secondary treatment. Dry ice is solid at
Heat Treating of Custom & Precision Springs - ACEAce Wire Spring & Form Co., Inc. was founded in 1939 in McKees Rocks, Pennsylvania. It was built on the design creativity of an ambitious father and the business acumen of his aspiring son. The enterprising father/son partnership laid a foundation for growth, innovation, and attention to customer needs.
Feb 19, 2010 · For a hardness of Rc45, which would be in the 'spring steel' range, a good starting point would be 425F. Both the heat treating and tempering should be done in a controlled temperature furnace to assure even heating.
Heat treating annealed 1095 spring steel Apr 28, 2015 · Preheat oven to 1,500F (oven is small and loses heat fast when door is open). Set spring on heavy stainless plate, put in oven, and dial back to 1,475F. From that point, cooked for 15 minutes including time for oven to come back up (about three minutes). Pull plate and spring together, tilt the plate, and let it fall into the quench oil.
Heat treating coil springs - can it be done? - Tech Talk Apr 08, 2013 · I know that coil springs are steel. I know that the best way to increase the stiffness of a steel piece is to heat treat the steel in an oven or furnace, and then quickly cool, or quench the steel using water or oil. This should be easy enough to accomplish given access the metallurgy lab on campus.
I've dabbled a little bit in tempering steel, but not with springs. But if you wanna try, one of the simplest methods of hardening/tempering is as follows:Heat it red hot with a torch. Then drop it in a cup of water when it's red hot all over. This hardens the spring, but makes it very brittle, like glass.
How to Heat Treat 5160 - Knife Steel NerdsApr 01, 2019 · Because the hardness was flat above 1500°F, grain growth is more likely. 1525°F is the recommended temperature of heat treatment in the ASM Heat Treaters Guide. With tempering there was a peak in toughness with a temperature of 400°F, with slightly less using a 375°F temper.
How to Heat Treating 1075 Carbon Steel - Practical MachinistAug 23, 2014 · 1) heat to bright red color (under low lighting conditions) with carburizing flame. 2) quench to 300°F (watched for no smoke from quenching oil coming off part) 3) heated to 560°F and held for 20 minutes minimum (used a bearing heater and watched for blue color on
Stainless Steel Type 302 Stainless Steel 302 is widely used because of its corrosion resistance and physical properties. SS 302 obtains its spring temper condition by cold working. Though it is categorized as being a nonmagnetic stainless, SS 302 becomes slightly magnetic as a result of cold working. It is not hardenable by heat treatment.
Re-Arching Leaf Springs a Lost Art Hagerty MediaJun 20, 2006 · The heat-treating process erases the springs memory by annealing each leaf in the spring pack individually, reshaping it and re-heat treating it. After disassembling the pack, each leaf is heated to at least 1,650 degrees Fahrenheit to clear its memory.
Springmaking Without Tears Top Rated Supplier of Firearm If your spring is not too large, a propane torch is all you need. For the larger and thicker springs something more may be needed. I used an acetylene torch with a slightly carburizing flame on the V springs and a propane torch for the lever action spring.
The Heat Treatment of Steel Spring Wire Spring material is often purchased either as pre-hardened wire or in the soft (i.e. annealed) state then heat treated (Fig. 1). This article explores the various heat treatments that are performed on both types and considers the properties of interest that may result. Types of Heat Treatments Stress ReliefHeat Treating for most spring? - Heat Treating, general May 17, 2013 · Heat treating scrap steel will depend on what alloy the original spring was made of, (5160 in old trucks, but any number of alloy spring steels these days) but in very general terms it requires heating to cherry red, quench in oil and then temper between 500 - 700 deg F. Lower temperature end gives more spring but may crack under heavy loads, higher end will give more flexability so it
