Tru-Spark Case Hardening Compound This unique product requires only two or three minutes at high temperature to achieve a good wearing surface with fine grain structure, ideal for hardening frizzens to spark well. You will need a Oxygen Acetylene torch for hardening a frizzen. Small steel parts may be hardened using a Propane torch.
Carburizes surfaces quickly to uniform depth while retaining the toughness of the core. Also protects delicate, highly finished work, and helps eliminate the need for remachining. Simply apply the hardening compound to your metal parts, heat to the required temperature, then quench in oil or water for a professional grade, heat-treatment.

I test out case hardening compound on mild steel. Results as expected. It makes a thin crust of hard but the underlying steel remains baby poop soft. T-Shiq355gnh steel hardening compound
Here is a heated part with clump of Kasenit case-hardening compound ready for reheating. Annealing steel is the process of wiping the blackboard clean, so to speak, by returning the metal to its dead-soft stage. In most cases, this is done by heating the metal to red hot and cooling it slowly.
I made a few mild steel screwdrivers. I want to harden the tips to use them for prying. Is there a recipe to make some case hardening compound that works with relatively easy to find components?
As most of you know, case hardening is time dependent. For any measurable amount of depth, the part has to be held at temperature (>1550F). This is from Case Hardening Steel : Pack, Carbonnitriding and salt surface hardening Carbonnitriding starting with low carbon steel (SAE 1008): 1 hour @ 1425 to 1450F results in a case .004" deep.
If you like to tinker with, well just anything, you may need to case harden a steel part. It's easy with compounds like "Cherry Red". Maybe you polished your AR15 disconnector too much, now your q355gnh steel hardening compound
Surface Treatment of Low Carbon steel. CASE HARDENING, is the process of producing a hard surface on wrought iron and steel parts by increasing the carbon in the surface by absorption, then hardening by the usual method (heat and quench). Finished low carbon steel parts are packed in a ceramic, graphite or steel box with powdered charcoal.
The powder sticks to the hot piece in a thick cake. Then heat up the piece to bright red (cherry is the usual description but cooked carrots is a better description IMHO). The carbon from the compound then diffuses into the surface of the steel - this takesa bit of time so give it a minute or two at this temperature. Now dunk into cold water.
May be used on steel, cast, wrought or malleable iron. Just brush on and then heat treat at up to 1,650 for 50 minutes. Features. A rapid compound for surface hardening. Up to .020" case depths in 50 minutes. For fine work & very rapid hardening. KASENIT Surface Hardening Compound
Case hardening on often found on lower cost files and has been used in the metal industry almost since the start of modern metal working. Cherry Red instantly case hardens steel parts with no special heat-treating equipment required.

Cherry Red Surface Hardening Compound is an easy way to harden soft, low carbon metals. Cherry Red in combination with high heat creates a tough, durable, hardened finish on the surface of metals. Produces a wear surface (surface hardening) on low carbon steel, low alloy steel, iron.
Steel is an alloy of iron and carbon, and sometimes other elements.Because of its high tensile strength and low cost, it is a major component used in buildings, infrastructure, tools, ships, automobiles, machines, appliances, and weapons.
I have read the details with some interest, I have at times used leather shards as a case hardening compound. Small pieces of leather from an old shoe is fine and put the item (small) into a piece of tube and cook in a flame or fire for an hour or so.
The term case-hardening is derived from the practicalities of the carburization process itself, which is essentially the same as the ancient process. The steel work piece is placed inside a case packed tight with a carbon-based case-hardening compound. This is collectively known as a carburizing pack.
The speed at which carbon diffuses into steel depends upon the temperature and the difference between the %carbon in the steel and the %carbon in the compound or atmosphere. At 1750F and a carbon potential of .6% in the carburizing compound, a .20% steel will absorb carbon at the rate of about .007 inches per hour.
For maximum hardness and strength, a hardening heat treatment is necessary. The stainless steel alloys shown in the table on Page 3 were heated as sheet samples for 60 minutes per inch of thickness at 1800F (982C) for Type 410 and at 1900F (1038C) for Types 420, 425 Modified, and 440A, and then air cooled to room temperature. The as q355gnh steel hardening compound
Case depth varies based on the type of steel and thoroughness of the heat applied by the user, but it is generally less than ten-thousandths of an inch. The process imparts several parts-per-million of carbon into that case hardened surface.
This Cherry Red case hardening compound is the perfect and modern hardening compound. Just bring the product up to a cherry red color and put some on and its case hardened. Cherry Red instantly case hardens steel parts with no special heat-treating equipment required.
Case Hardening Steels. Case Hardening steels are steels which after carburizing, in solid liquid or gaseous media, followed by hardening, present a hard wear resisting surface layer combining with the compression stresses involved to increase fatigue strength.
HEAT TREATMENT OF TOOL STEEL 5 Uddeholm Dievar, hardened structure. Austenite has a higher solubility limit for carbon and alloying elements, and the carbides will dissolve into the matrix to some extent. In this way the matrix acquires an alloying con-tent of carbide-forming elements that gives the hardening effect, without becoming coarse q355gnh steel hardening compound
Case hardening (or carburization, as it's referred to today), traditionally involved wrapping low-carbon steel in a "case" of carbon-rich material - typically hardwood charcoal - and then sealing it with clay and heating it to austenizing temperatures over the course of many hours and sometimes even days.
applied to duplex and precipitation hardening 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]. SURFACE HARDENING OF STAINLESS STEELS Grain boundary M 23C 6 Boundary of passivity
D2 tool steel is an air hardening, high-carbon, high-chromium tool steel possessing extremely high wear resisting properties. It is very deep hardening and is practically free from size change after proper treatment. This tool steel's high chromium content gives it mild corrosion resisting properties in the hardened condition.
FURNACE ATMOSPHERES 3 Nitriding and Nitrocarburizing 5 (below A1). The term carbonitriding on the other hand should be reserved for treatment temperatures where the steel is austenitic. Nitriding is the term used for classical gas nitriding in ammonia. As the name indicates, it is a process where nitrogen is transferred to and taken up by the q355gnh steel hardening compound
