EDM or Electrical Discharge Machining is the burning/melting of the steel to form a tool or part. Proper heat treat of the steel is an ABSOLUTE MUST in preparing for the EDM process; 3 tempers […]
A customer is building a tool/part and wants to know what grade of steel do I need to use? Here are some good starting questions to ask. This list doesn’t cover everything, but it will […]
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, […]
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 […]
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 […]
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 […]
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 IS AN ASPECT OF HEAT TREATMENT […]
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 […]
What is heat treating? Simply defined, it is the controlled heating and cooling of steel in order to enhance certain mechanical and physical properties. We could go into a deep metallurgical explanation, but you would […]
HISTORY OF TOOL STEEL
TOOL STEEL HISTORY DATES BACK MORE THAN 1,000 YEARS, BEGINNING IN CHINA, DAMASCUS, AND JAPAN WITH THE FORGING OF SWORDS UTILIZING LAYERS OF DIFFERENT TYPES OF STEELS, COMMONLY KNOWN TODAY AS “DAMASCUS”. […]
