What is the BBNSteel A588 Grade K properties quotation

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, A588 Grade K properties and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.

As a common steel plate in the steel market, A588 Grade K properties, manganese steel plate has the following characteristics. First, good toughness, stretching and crimping can be done well. Second, the bearing strength of manganese steel plate is good and it can bear a lot of gravity. Third, the A588 Grade K properties, manganese steel plate is easy to weld, easy to process finished products, and its price is relatively low. Fourth, manganese steel plate has good corrosion resistance, and long service life. Fifth, the manganese steel plate has good mechanical properties, low temperature performance, good plasticity and weldability.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the A588 Grade K properties quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After A588 Grade K properties quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

In 2016. Our company offer 1200 tons API 5L GR.B hot rolled coil to Bangladesh——100 tons for 3.9*625mm, and 1100 tons for 7*683mm. It is one tender project, we get the tender at the end of 2015, and arrange the production in 2016. They required the tolerance of thickness is +0.1/-0.2mm, and width tolerance is +/-0.5mm, which is a very high requirement for coil tolerance, but our mill handling this very well. and our Q/C department witness all of the process.
