Several different diagrams and charts can be derived from the basic all-encompassing diagram; some of which are very specific to a given material, temperature or set of properties. Stress relief annealing is the treatment given to steel to relive the locked-in stresses due to the manufacturing ...

Heat treating:(as done by Paul Bos) AST-34 is a secondary hardening steel. That means it gets harder with the freezing and tempering, usually gaining 2 -3 Rc points. Heat to 1975 ℉and soak for 40 minutes. Quench in Argon or rapid quench in air, straighten as necessary before freezing...
The book is also broken up into digestible chunks. There are four major sections: 1) Steel and Knife Properties, 2) Knife Steels and their Metallurgy, 3) Processing and Heat Treating Steel, and 4) Knife Making. Each section has 5-10 chapters in it for a total of 29, each chapter ave...

Pop’s Knife Supplycontacted me about doing a set of experiments on their 8670 steel. We talked about different heat treating variables we might test andJoey Berryof Pop’s heat treated and ground the coupons. I measured the hardness and toughness of each condition and I am providing the ana...
furnaces for reheating of steel slabs, blooms and ingots Walking hearth furnaces for reheating of steel billets or rounds Bogie hearth furnace for stress relieving The purpose of heat treating steel is to change its mechanical properties, such as ductility, hardness, yield strength and impact ...
3. There is no direct conversion between Rockwell and Vickers hardness.ASTM E140gives conversions for some bulk materials like stainless steel. Charts have also been developed based upon microhardness of standard Rockwell test blocks. 60 HRC is approximately equal to 750 HV. 65 HRC is approximately...
The strands lay down on a stainless steel incline slide containing water. At the end of the slide, the strands with water go into the pelletizer to be cut. Pellets and water from the cutting chamber are transported to a dewatering unit and centrifugal-type dryer for drying. Figure 44.9 ...
both cases so it was not a difference in hardness tester. I am not sure what the reason for the offset was. Perhaps it was the result of a different heat of steel, or a difference in furnace, or cooling rate in quenching. It’s hard to know for sure without investigating it ...
