Dongkuk Industries Co. Ltd., the largest manufacturer of cold-rolled medium-carbon and high-carbon steel strip in South Korea, placed an order with Ebner for a hardening and tempering line. According to Dongkuk Industries, it will be the first facility of its kind in East Asia. Ebner’s scope of supply includes an austenitizing furnace, a HICON/H₂Q hydrogen quenching system, a FlexFlat martensite cooler with SmartFlat automatic flatness supervision system, a leveling furnace and an atmosphere jet cooler. A combined bainite/pearlite transformation zone will also be supplied. Medium- and high-carbon steel strip will be hardened and tempered in the facility starting in the summer of 2021.

Can-Eng Furnaces International Ltd. has been awarded a contract to design and build a 1,500-pounds/hour mesh-belt furnace system for the austenitizing and molten salt quenching of unique components used in the manufacture of drivetrain systems.

PhoenixTM supplied a hot-box oil-quench monitoring system to Musashi Auto Parts Inc., a Canadian auto-parts manufacturer.

The rolling and thermal treatment of forged rings sometimes leaves residual stresses that cause dimensional distortion.

Hardenability is the ability of steel to partially or completely transform from austenite to some fraction of martensite at a given depth below the surface when cooled under a certain condition. The “gold standard” test for all hardenability results has always been the “Jominy End-Quench Test.”
