With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
Annealing 316 and 316L stainless steels requires heating to between 1,900 and 2,100 degrees Fahrenheit (1,038 to 1,149 degrees Celsius) before rapidly quenching. Differences Between 316 and 316L 316 stainless steel has more carbon in it than 316L.
The best temperature range to achieve optimal heating is between 1900 and 2150F. The heating treatment should be followed by air cooling or a water quench. However, keep in mind that 316 stainless steel tubes cannot be hardened by heat treatments. Corrosion Resistance. This type of stainless steel contains anywhere from 16-18 percent chromium.
Solution Annealing & Heat Treatment. To save you time and money, Best Stainless offers a variety of inventory in heat treated steel conditions. In addition, we also keep inventory on hand capable of heat treating per specification. Heat treatment services include solution annealing, quenching, tempering and stress relieving.
Topic Welding Industry / Technical Discussions / Is it ok to Quench 316 Austinetic stainless steel By david bean Date 07-07-2010 18:06 Edited 07-07-2010 18:12 I just walked in to our sister shop (an architectural fab shop) to see the shop lead attempting to heat straighten a piece of 316 Stainless Steel.
Ferritic Stainless Steels Ferritic stainless steels are not hardened by quenching. The only heat treatment applied to ferritics is annealing because they develop minimum hardness and maximum ductility, impact toughness and corrosion resistance in the annealed and quenched condition.
Corrosion resistance of stainless steel varies by grade. The two most common stainless steel grades are 304 and 316. The key difference is the addition of molybdenum, an alloy which drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments. 316 stainless steel contains molybdenum, but 304 doesnt.
Hardening 304 stainless steel. A discussion started in 2004 but continuing through 2019. 2004. Q. I have a local college that wants to harden stainless steel cutters made of 304 stainless, and I would like to know if you have a procedure for this. David M. Brower machine shop - Columbus, Ohio
stainless steel grades. Materials to be treated by low-temperature carburising should be in the solution annealed condition. Sharp edg-es, the inside of bores and gaps present no limitation to the process [4, 11, 12, 13].

Wayne Goddard says sending his stainless blades to Paul Bos is just too good a bargain to pass up if you send in bulk. Perfection in heat treat, with cryo if you want it. On the other hand Ed Fowler posted some time ago that the best performance he'd ever gotten out of 440C was with the triple quench/draw in oil method.
faz says: 316 grade is austenitic while 416 is martensitic stainless steel best quenching 316 stainless steelboth have different composition and application. 416 have high sulphur content and not suitable in marine or any chloride exposure. 316 is not hardenable by heat treatment while 316 have superior corrosion properties than type 416.
#50 quenching oil comes close to matching the quench speed of water. However, #50 will give you a less severe and a much more uniform quench that water will. This is a good quenchant to use with 1095 high carbon steel. AAA quenching oil is the most popular and widely used quenchant offered by Park.
Types 316 and 316L are molybdenum-bearing austenitic stainless steel which are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium nickel austenitic stainless steel such as Type 304. These alloys also offer higher creep, stress-to-rupture and tensile strength at elevated temperature.
Cast iron (and also some high tensile steel) will crack when cooling down, is very hard to weld because shrinking when cooling, creates tension beyond breaking strain. Regular 316 stainless is very tough, will deform instead. I have never seen 316, welded with proper rod, crack after welding, even on thick pieces.
Testing two different quenching process for stainless steel. Oil quench is what you see more often and for most high carbon steel, it's also what I have done in every single one of my build video best quenching 316 stainless steel
Can anyone give me tips on quenching 304 stainless (post weld). Until a few months ago, I thought all welding material should be cooled as slow as possible. Then I read that some industrial kitchen fabricators keep a wet rag handy to quench. Then I do research and come to understand that quenching 304 stainless actually anneals the stainless.
Martensitic stainless steels can be hardened via heat treatment; how hard they can get depends on their carbon content. The more carbon these steels contain, the more hardenable they are. For example, hose clamp screws are typically made of 410 stainless steel.
17-4, 17-7, 15-5, and 15-7 stainless steels are hardenable but not from heating and quenching. The way they harden is by aging in a heat treatment for several hours at an elevated temperature. Welding actually may soften a zone in these metals. Using a carbon steel brush will cause rust on stainless steel. Dont do it.
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.
At Best Stainless and Alloys, we stock a large variety of stainless steel bars and nickel alloys, and we are one of the nations leading distributors in Pump Shaft Quality (PSQ) material. Choose from our selection below to view the materials we distribute.
Common media for quenching include special-purpose polymers, forced air convection, freshwater, saltwater, and oil. Water is an effective medium when the goal is to have the steel to reach maximum hardness. However, using water can lead to metal cracking or becoming distorted.
THE HEAT TREAT DOCTOR: Stainless Steels Part Two: Heat Treatment Techniques by Daniel H. Herring Posted: June 14, 2006 Heat treating of stainless steels depends to a great extent on the type (wrought or cast) and grade of stainless steel, as well as the reason for the treatment, most often to

Quenching. Quenching - is the process of rapidly cooling the metal from the solution or austenitizing treating temperature, typically from within the range of 815 to 1100 C (1500 to 2012 F) for steel.
Stainless steel is used for buildings for both practical and aesthetic reasons. Stainless steel was in vogue during the art deco period. The most famous example of this is the upper portion of the Chrysler Building (pictured). Some diners and fast-food restaurants use large ornamental panels and stainless fixtures and furniture.
As, for example, the best stainless steel kitchen sinks some with a drain settings on the rear side or at the back of the sink. Such a positioning of the drainage pipe enables the user to accommodate the garbage basket and containers easily, below the sink, in the cabinet area.
Two of the more commonly used grades of austenitic stainless steel are grades 304 and 316. To help you determine which grade is right for your project, this blog will examine the difference between 304 and 316 stainless steel.
One thing to remember about stainless steel, is that there are tons of alloys, and they are all different, and act differently. But 304, which is the most common in the US, can be annealed with heat. You heat it up to red, quench it, and it will be as soft as it ever is gonna get- which is still pretty hard, but noticeably easier to drill, or bend.
Heat treating 316 stainless steel? My son and i are new to blacksmith work and have successfully made two spring steel knives. I was given a stock of 316 stainless and am not sure if i need to heat treat and temper like spring steel.
Stress relieving heat treatments for austenitic stainless steels Introduction. Unlike martensitic steels, the austenitic stainless steels are not hardenable by heat treatment as no phase changes occur on heating or cooling. Softening is done by heating in the 1050/ 1120C range, ideally followed by rapid cooling.
This is why Marlin Steel typically stocks grade 304 and grade 316 stainless steel. Each of these alloys are high-performing in terms of tensile strength, durability, and corrosion resistance. Grade 304 SS stands up to a variety of environments, while grade 316 SS has improved resistance to chlorides and other corrosives.
