Hardening Mild Steel Heat Treating general discussion

Can mild steel be hardened?Can mild steel be hardened?Mild steel can be either case hardened ( a thin layer of carbon will be absorbed by the steel and it will make for a hard case with mild steel inside - hence the term) and WORK hardening. . .which is done by beating the steel until you compress the molecules together and it;s a bit harder than before.Hardening Mild Steel - Heat Treating, general discussion Hardening Mild Steel Heat Treating general discussion Does tempering steel reduce martensite?Does tempering steel reduce martensite?No. The tempering reduces the amount of martensite and thus makes the steel softer. Heating it again to a lower temperature will not introduce additional martensite. The only way to do that is to heat it until the metal de-magnetises, quench it again, and then temper to the desired hardness.How to Harden Steel 10 Steps (with Pictures) - wikiHow

Hammer hardening - Heat Treating, general discussion - I Hardening Mild Steel Heat Treating general discussion

Apr 01, 2009To harden I've found that heating the hammer to right above magnetic and then cooling the whole thing in water gets it deeply hardened. Then, to temper it I put it in the vice with a mild steel heat shield placed over the threads of the vice and use a torch to heat from the center of the eye until the face and pein reach the bronze to purple range. What is heat treatment steel?What is heat treatment steel?This heat treatment process carried out for steel parts which have been already hardened, in order to reduce bitterness and unequal stress develop as a result of hardening. This process reduces brittleness and hardness but improves the tensile strength of Steel. It increases the toughness of Steel at the expenses of loss of some hardness.Heat Treatment- Annealing, Normalizing, Hardening, Tempering, Nitridi

ASSRA Forum - Heat treating

I noticed under various topics the discussion of annealing and case hardening. Having been a toolmaker and involved with heat treating for 30+ years I don't see how you can apply any amount of heat to an action or critical part without knowing what the material you are working with such as 1010, 1018, 8620 etc.Case Hardening at Home - Practical MachinistMay 31, 2016Also read that a long soak in melted hardening salts will help to assure a deep hardening. Steel would likely be 1018 or T1. Also heard that hardening salts will eat through a stainless steel envelope made of the usual heat treat foil so not sure what sort of crucible would be needed for a good soak time. Thanks, Randy

Dimensional Changes After Heat Treatment

May 07, 2013Discussion during the meeting helped to clarify that the amount of size change during heat treatment was not important. What was important was that it be consistent part-to-part, load-to-load and batch-to-batch. The manufacturer and the heat treater proceeded to list all of the variables that would affect size change during heat treatment.Dimensional Changes After Heat TreatmentMay 07, 2013Discussion during the meeting helped to clarify that the amount of size change during heat treatment was not important.

Fundamentals of the Heat Treating of Steel

Chapter 2 Fundamentals of the Heat Treating of Steel / 11 Steel, however, is by far the most widely used alloy and for averygood reason.

Tempering is a type of heat treatment for iron-carbon alloys. These alloys are more formally called steel. In general, the process for heat treating steel is accomplished by heating, rapid cooling, and reheating of the chosen material. When steel is cooled quickly, the atoms are frozen in an unstable position.Laser Hardening - an overview ScienceDirect TopicsThis is referred to as case hardening.
