We specialize in the production of steel pipe, including hot-rolled seamless steel pipe, ERW steel pipe, LSAW steel pipe, spiral welded pipe, stainless steel pipe, RHS / SHS, LR DH36 shipbuilding steel plates. The company's annual sales volume is 75000 tons, more than doubling in the past five years, mainly used in machinery, pipeline, heating, oil drilling, chemical industry, agricultural irrigation, urban construction and other industries. So far, our pipeline service customers come from more than 40 countries.
Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, LR DH36 shipbuilding steel plates included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.
The LR DH36 shipbuilding steel plates processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the LR DH36 shipbuilding steel plates steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.
