BBNSteel served SA 516 GR 70 boiler quality plates to many industries like oil, gas, petrochemicals and because of having a high demand for sa516 Grade 70 boiler steel plates by our worldwide clients. We ensure that the LR DH36 watercraft structural steel material is always in stock and available to you from our warehouse. So we always make sure to provide all the ordered products on time with our big delivery network.
Our company's LR DH36 watercraft structural steel power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the LR DH36 watercraft structural steel utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the LR DH36 watercraft structural steel 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 LR DH36 watercraft structural steel quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
Low alloy high strength steel plate is made by adding a small amount of alloy elements on the basis of carbon structural steel (carbon content 0.16% ~ 0.2%). LR DH36 watercraft structural steel, Low alloy high strength steel plate has good welding performance, plasticity, toughness and processing technology, good corrosion resistance, high strength and low critical transition temperature of cold embrittlement.
We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
