In the glossary of this book (see Appendix A, Glossary of Heat Treat-. ing Terms) the principal portion of the denition for steel is an iron-. base alloy, malleable in some temperature range as initially cast, contain-. ing manganese, usually carbon, and often other alloying elements.
Place the blank, the unfinished piece that will become your knife blade, in the heat treating oven and heat slowly to between 1,550 and 1,650 degrees Fahrenheit to anneal it. This process removes any prior heat treatment and makes the metal soft enough to grind or otherwise shape. Do not heat faster than 400 degrees per hour.
You will also need High Temperature stainless steel foil to protect the blade during the soak at high austinizing temps. One of the most forgiving SS is AEB-L easy to grind reasonably priced. The heat treat protocol can be found in the "Stickys" under Heat Treating.

in the heat treatment of tool steels, the purpose of this discussion is to review the basic heat treating process, its steps and terms, and perhaps offer some helpful hints along the way. The Heat Treating Process The process consists of: A) PREHEATING the Annealed tool, typically at 1250 degrees F. B) AUSTENITIZING (Soaking at High Heat).
Stainless steels are generally heat-treated based on the stainless steel type and reasons for carrying out the treatment. Heat treatment methods, such as stress relieving, hardening and annealing, strengthen the ductility and corrosion resistance properties of the metal that is modified during fabrication, or generate hard structures capable of tolerating abrasion and high mechanical stresses.
Heat treat instructions for this grade can be found in the ASM Heat Treaters Guide. This reference does state that higher temperatures and longer times are needed to dissolve all the carbides in D7 than in other D series tools steels.

The approach to heat treatment selection. As a general guideline, it is advisable that the range 480-900 C is avoided. The low carbon (304L or 316L) or the stabilised (321 or 347) types should not be at risk from corrosion sensitisation during stress relieving treatments.
Heat-treatment (tempering) austenitic spring grades. This includes the austenitics, which can be 'tempered' in the range of 250 / 425C, 30 minutes to 4 hours for wire and 250/450C, 30 minutes to 24 hours for strip. BSEN 10151 has graphs showing the increase in tensile strength range, depending on the initial strip cold rolled strength in Figureshow to heat treat ss 0cr18ni11nb plate
Testing my new heat treating oven. Heat treating a 440C knife blade . Oven temp 1980 F to less than 100 in under two mins.
Like other stainless steels Nitro-V has high hardenability so it can be cooled in air or plate quenched for hardness. Oil quenching is also possible though plate quenching is good for helping to maintain flatness. I recommend cryogenic processing for maximizing strength when heat treating. You can read more about cryo here: Part 1, Part 2, and how to heat treat ss 0cr18ni11nb plate
Open the air vents on your Weber Bar-B-Q and remove the cooking grill. Lay down a layer of charcoal on the charcoal grill and light it. Using a torch, heat your steel item until it glows red-hot. Do this very close to the Webber grill.
PGI Heat Treating At Precision Grinding, we stress relieve and anneal steel parts and fabrications every day of the work week. Heating processes such as annealing and stress relieving remove the inherent stress properties in steel, improve the machine-ability, and allows us to grind parts to higher flatness standards.
Some Thoughts on Stainless Steel and Heat Treating Posted on May 7, 2012 by Podforge Theres always going to be debates among knifemakers and knife enthusiasts about the best kind of steel.
Predicting Size Change from Heat Treatment Last updated on 8/26/2019 While a precise forecast of a steel parts size change during heat treating cannot be expected, by considering potential factors, a heat treater can provide a reasonable estimate that can help the shop prepare for final machining operations.
420 stainless steel is a martensitic higher carbon version of types 410 and 416 stainless that can be hardened by heat treatment. It contains a minimum of 12 percent chromium, sufficient to give 420 corrosion resistance properties.
While not all aluminum alloys benefit from heat treatment, we can heat-treat several alloys to increase the ease of forming or the strength of the finished product. Unlike steel or iron, aluminum requires rigid heat control to achieve optimal results, so special equipment is often required.
316 1.4401 316L 1.4404 Heat Treatment. Annealing The austenitic stainless steel are provided in the mill annealed condition ready for use. Heat treatment may be necessary during or after fabrication to remove the effects of cold forming or to dissolve precipitated chromium carbides resulting from thermal exposures.
and/or heat treating them below or above the beta transus. Compositions, sizes, and distributions of phases in these two-phase alloys can be manip-ulated within certain limits. As a re - sult, alpha-beta alloys can be hardened by heat treatment, and solution treating plus aging is used to produce maximum strengths. Other heat treat-
CRUCIBLE 440C (AISI 440C) Crucible 440C is a heat treatable stainless steel, designed for a combination of high wear resistance and moderate corrosion resistance in mild environments.
Because AEB-L keeps popping up in several threads I'll post how I do my treatment of this steel. I highly recommend that you make 5 test coupons, heat the first one to 1900'f and plate quench, second to 1925'f, third one to 1950'f, 1975'f, 2000'f.
Heat tends to even out. If you try to heat treat steel without something to keep the heat in, it will be very difficult to maintain a temperature, and a lot of the heat will get wasted. That is why we will build a furnace chamber out of bricks. Try and find bricks that are rated for the highest heat resistance. Lay out a layer of bricks flat how to heat treat ss 0cr18ni11nb plate
Heat Treating Information: Preheat: Heat to 1400 and equalize. Austenitize: Ramp to 1900-2000F and hold at temperature for 30-60 minutes. Oil or plate or air quench to below 125F. Temper: Twice at 400-1200F for 2 hours minimum each time. Tempering at 800-1100F will result in a minor reduction in both corrosion resistance and toughness.

I try to bridge the gap between in-depth theoretical explanations of heat treatment, and rote tradition.
ATI 15-5 precipitation hardening stainless steel flat-roll product is produced in the annealed condition. This is also called the solution heat treated condition, or Condition A. Annealing is conducted by heat treating at approximately 1900F (1040C) to 1950F (1065C) and cooling to room temperature.
