ASM’s subcommittee recommends that a long-cycle deep-cryogenic treatment (DCT) followed by a low-temperature temper (LDCT+T) should be the standard DCT practice. Many investigations by researchers using this standard and case studies cited positive results, but there have also been investigations that cited negative results.

SECO/WARWICK will deliver two vacuum furnaces to Flansch-Tech, a specialist in aluminum and steel forging, in Budapest. According to SECO/WARWICK, one of the vacuum furnaces will be the largest in Hungary. The Vector with horizontal charge loading is equipped with a 15-bar nitrogen cooling gas-pressure system and a production work area of 900 mm wide x 900 mm high x 1,200 mm long). It will be used for the heat treatment of tool steels – mostly dedicated to hardening and tempering – and will allow Flansch-Tech to process larger parts.

Lucifer Furnaces Inc. designed and delivered a dual-chamber furnace for heat treating high-speed steels.

L&L Special Furnace Co. Inc. delivered a highly uniform box furnace to a quality-control lab of a major U.S. steelmaker.

The subject of carbide formation in steels has intrigued The Doctor ever since he first peered into a microscope and observed them.

RA 602 CA® – also known as 602 CA® and NiCroFer 6025, which are trademarks of VDM – is a relatively new heat-resistant alloy with excellent creep strength at very high temperatures and oxidation resistance up to 2250°F (1232°C).

What is meant by the terminology of secondary hardening?

Once the tool steel has been quenched and has cooled down to a temperature of (approximately) 150°F, it is critical to temper the tool steel immediately.

Preheating of tool steels for austenitizing procedures is very critical.
