At present, BBN steel has successfully developed Grade D40, E40 and other high-strength and high-toughness structural steel plates for offshore engineering, E550 and other quenched and tempered ultra-high-strength offshore platform steels, quenched and tempered GL-E40 hull steel plate, API 2W Gr50 and other TPCP platform steels, and DH36-Z35 offshore oil platform steel, SM490, SM400 series of H-shaped steel for offshore oil platforms, etc., basically formed the serialization of high-strength steel for offshore platforms.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the quenched and tempered GL-E40 hull steel plate 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 quenched and tempered GL-E40 hull steel plate quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
Unlike general steel manufactures, other than regular fresh production, we also have huge stocks. What is more, we offer cutting, welding, drilling, bending, etc. deep processing for the steel materials. That enable us to meets various quenched and tempered GL-E40 hull steel plate steel sizes and shapes requirements of clients.So, if you have any steel demands, or steel processing needs, please do not hesitate to contact with us. We will try our best to make you stisfied.
