Heat Treating of Tool Steels – Hardness

Tools Steels – Hardness
The next topic to discuss is rockwell hardness. Hardness is the resistance of metal to plastic deformation usually by indentation. Indentation is usually measured by various hardness tests, such as brinell, rockwell, knoop and vickers. The most common tests are brinell & rockwell scales.

The term hardness may also refer to resistance to […]

Heat Treating of Tool Steels – Tempering

Tempering Tool Steel
The 7th process to discuss is tempering.  Tempering is key in developing the final properties of the steel and, in the sequence of the heat treat cycle, is extremely important to perform immediately after quenching.

Tempering is reheating hardened steel to convert untempered martensite produced by the proper quenching cycle, to tempered martensite & […]

Heat Treating of Tool Steels – Quenching

Quenching
The 3rd term to be discussed is quenching and the desired outcome from this process.

The quenching operation is extremely important in setting up the proper microstructure of the steel.  There are many mediums that can be used to quench steel such as oil, air, salt and steam to name a few.

The purpose of quenching is […]

Heat Treating of Tool Steels – Hardening

The 2nd term to discuss is the hardening process and what transformation the steel goes through during the hardening process.

Hardening (A specific heating and cooling process based on the chemistry of the material) is performed on all ferrous steels to develop the proper microstructure and optimal properties of the material.

The 1st stage of hardening is […]

Heat Treating of Tool Steels – Annealing

THE NEXT FIVE BLOG TITLES WILL DEAL WITH DIFFERENT ASPECTS OF HEAT TREATING TOOL STEEL.  THESE FIVE TOPICS WILL BE, IN ORDER: ANNEALING, HARDENING, QUENCHING, TEMPERING, AND HARDNESS RANGES/TESTING.
ANNEALING
ANNEALING IS AN ASPECT OF HEAT TREATMENT USED TO SOFTEN STEELS AND TO IMPROVE MACHINABILITY, MATERIAL STABILITY & MECHANICAL OR ELECTRICAL PROPERTIES. THIS IS ACCOMPLISHED BY BRINGING […]

Working With Your Heat Treater

Over the years we’ve learned of many success stories and even more failures with regard to the outcome of a heat treated tool or piece of steel.  The discussion following the failures is seldom calm and, hindsight being 20/20, most of the failures could have been avoided if the details were discussed during the early […]
