It has been 110 years since the tragic sinking of the unsinkable ship, the RMS Titanic. The first part of this article focused on the bow and stern riveters and the riveting process itself. This second part dives deeper into the sinking of the ship.
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.
Romania’s TMK-Artrom granted SMS group the final acceptance certificate for a tube-and-pipe heat-treatment line that was ordered in March 2016. Designed for an annual capacity of 160,000 tons, the line will be used for the production of seamless high-strength pipes up to a wall thickness of 60 mm (2.36 inches) for mechanical applications and OCTG pipes.
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.
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.”
This article takes a look at the benefits, needs and objectives of a quench-press, and explains why manufacturers who deal with distortion during heat treatment may want to consider what a quench-press could do for their products’ quality and cost.
