VL E460 steel: is a structural steel plate for ships and offshore engineering."VL" stands for the abbreviation of "DNVGL", which is a standard certified by the two classification societies of DNV (Norway) and GL (Germany). The yield strength is 460. Different classification society certifications, different grade requirements and different yield strengths can be selected according to different needs.
Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium CCS A40 bulk ore carrier steel carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some CCS A40 bulk ore carrier steel alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
With equipment, technology, production technology, quality supervision and other leading advantages, we are leading in the production of all kinds of high-quality, high-tech medium, extra thick, extra wide steel plate CCS A40 bulk ore carrier steel shaped parts. The cutting surface is smooth and clean, the cutting edge is neat, without secondary processing by users, and it can be installed and used directly according to the technical dimensions, with the characteristics of high coincidence rate of positive and negative tolerance and excellent quality. The processed steel products are mainly used in heavy machinery and equipment.
