DELTA H Commissions Heat Treating System for Military Aircraft

By | Uncategorized

GUNSAN, SOUTH KOREA—DELTA H commissioned a Dual Chamber Aerospace Heat Treating (DCAHTTM) furnace system to the United States Air Force while visiting Kunsan Air Base in South Korea. These highly specialized furnaces provide crucial heat treating capacity for military aircraft while adhering to the strict calibration and record standards of the Armed Forces. DELTA H Chief Technology Officer and Founder Richard Conway was there when the innovative technology was presented. “As a USAF veteran, there are few things more gratifying than personally delivering to our warfighters the absolute best and most practical technology possible for heat treating aircraft parts,” Richard…

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…
