How to Harden Steel10 Steps (with Pictures) wikiHow

Jan 20, 2011 · Steel is a common durable alloy, and while most steel used in tools is already tough, you can harden it even more to prevent wear and tear. Hardened steel prevents knife blades from dulling and tools from bending and breaking. With a simple heating and quenching process, you can make your steel last for much longer!

Steel Wikipedia

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.. Iron is the base metal of steel. Iron is able to take on two crystalline forms (allotropic forms), body centered cubic and face centered cubic, depending on

7 Causes For Quench Cracking Of Steel Speaking of

Here are 7 ways that steel can fail as a result of Quench Cracking from heat treatment. Overheating during the austenitizing portion of the heat treatment cycle can coarsen normally fine grained steels. coarse grained steels increase hardening depth and are more prone to quench cracking than fine grain steels. Avoid over heating and overly long dwell times while austenitizing.

What is quenched and tempered steel? ShapeCUT

What is quenched and tempered steel? If the steel becomes too hard after quenching, it can be tempered. This involves heating the element again, but to a point far below the temperature reached in the quenching stage – usually around 540 degrees Celsius. The amount of time the quenched metal is tempered is the determining factor to how

Carburizing (Ohio, Indiana, Kentucky)Gas Carburizing

While the carburizing process can be used to case harden most low carbon steels, plain carbon grades such as 1010, 1020, A36, etc. should be avoided due to their poor response to oil quenching. For critical components an alloy carburizing grade such as 8620, 4820 or 9310 should be used.

A tempering process may then used to control the resulting hardness. For example, Tool steel A2 has a hardness of 63 65 Rockwell C after quenching but can be tempered to a hardness ranging between 42 to 62 HRC. Tempering prolongs the service life of the part, as it reduces brittleness (best results are achieved for a hardness of 56 58 HRC).
