Heat-Treated Steel Plates with Heavy Section and Large

in heat treated steel plates, i.e., quenched and tempered materials, which is superior from the viewpoint of improving the properties of extra heavy section plates. JFE Steel manufactures high quality, extra heavy steel plates by effectively utilizing the forging process, using large-scale ingots produced from high purity steels High Performance Steel Plates for Tank and Pressure for high quality heavy section steel plates, in which high reliability is required, by a combined forging and plate rolling process using continuous casting slabs2,3). The High Performance Steel Plates for Tank and Pressure Vessel Use High Strength Steel Plates with Excellent Weldability and Superior Toughness for the Energy Industry Quenching and tempering - voestalpineQuenching and tempering provides the steel with high strength and ductility. Quenching and tempering is a heat-treatment method for high-quality heavy plates. Quenching and tempering consists of a two-stage heat-treatment process. Stage 1 includes hardening, in which the plate is austenitized to approximately 900°C and then quickly cooled.

Steel Diamond Plate by the Piece

Steel diamond plate is a heavy duty checker plate material that serves many purposes. Perfect for many industrial uses such as flooring in mezzanine structures, factories and freezers. Our steel diamond plate is available in several thicknesses, quantity discounts are available. Strengthening and toughening mechanism of a Cu-bearing The microstructuremechanical property relationship of a Cu-bearing low-carbon high-strength low-alloy steel, subjected to a novel multistage heat treatment including quenching (Q), lamellarization (L) and tempering (T), is presented. Yield strength of 989.5 MPa and average toughness at 80 °C of 41 J were obtained in this steel after quenching and tempering (QT) heat treatments. Toughening of Low-Alloy Steel by Ultrafine-Grained Oct 19, 2016 · Microstructural design for improving the strengthtoughness balance was studied in low-alloy steel. Medium-carbon steel bars with microstructures of two types such as an ultrafine elongated grain (UFEG) structure and an ultrafine equiaxed grain (UFG) structure were fabricated by multi-pass warm caliber rolling and subsequent annealing. Conventionally, quenched and tempered steel with a
