Facts About Metal Hardness and Heat Treating

By News
Hardness is the nearly universal measurement of heat treating performance. This is because specific materials processed to the required hardness perform well under certain loads. For example, spring steel at a hardness of Rockwell C45 performs well as a spring. Experience has shown that a hardness of Rc45 in spring steel correlates with toughness, resilience, and high fatigue strength. The correlation is consistent and Rc45 is accepted as a quality hardness in heat-treated springs, even though the hardness itself is not an important characteristic of a spring. For many parts where tensile strength, toughness, or fatigue strength may be the…

Things to Consider When Purchasing an Industrial Oven:

By News
Things to consider when purchasing an Industrial Oven or Furnace This blog explains the importance of hardness, heat treating, stress, and design that must be considered when purchasing an industrial oven. Hardness Requirements Hardness requirements describe which hardness tests (Rockwell, Brinell, etc.) and range are required. For tool steels, a three-point hardness range is desirable, such as “Rockwell C 60-62.” Five to six points below Rockwell C 50 should be allowed in hardness. Inspection locations and critical areas in which hardness tests are not allowed should be noted. Stock removal for preparing surfaces for hardness checks should be noted, if…

DELTA H Heat Treating Solution Used to Restore Historic Plane

By Heat Treating, News, Projects
A DELTA H heat treating solurion is currently restoring a legendary plane to its former glory. The Lockheed Constellation is an elegantly designed propeller driven transport airliner for military and civilian use. Often referred to as "Connie" the airliner remained in production from 1943 to 1958. Restoration of planes like the Constellation typically happens for one of two reasons. They become a static display in a museum or to be made airworthy. Static display restorations ensure the plane is seen in its former glory which will allow future generations a glimpse of the past. According to the Strategic Air & Space Museum. In contrast, restoring a plane…

The Power of Heat Treating

By News
For most of my adult life, I have been involved in sales of one form or another. My big break into heat treating arrived when I joined Lab-Line Instruments where I learned about the wonderful world of heat applications. I have sold Incubators, ovens, furnaces, walk-in chambers; all using heat for everything from thawing plasma to mapping the human genome, or shelf life testing baby food formulas to curing cement for testing the roads we travel on. Over 95% of all that the modern world looks at, researches, or manufactures involves heat. Your house, your car, the tools you use,…
