hardox 450 steel grade PVQ steel plate
Our company has Hardox 450 steel grade strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply Hardox 450 steel grade deep processing service for products Hardox 450 steel grade like cutting, drilling, bending, welding and grinding.
ASTM A285 steel can be made into a variety of steel product forms, such as steel plates, Hardox 450 steel grade steel coils, and steel pipes. It has good welding ability and can be used for fusion welding required by pressure vessel equipment. Its maximum thickness is limited to Hardox 450 steel grade 50mm to ensure its mechanical properties.
The steel plate for hull structure is also called marine plate or shipbuilding steel. Due to the harsh working environment of the ship, the hull shell is subject to the chemical corrosion of seawater, so the requirements for steel for the hull structure are strict. First of all, good toughness for marine plate Hardox 450 steel gradeis the most critical requirement. In addition, it requires higher strength, good corrosion resistance, welding performance, processing performance and surface quality.
Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched Hardox 450 steel grade increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of Hardox 450 steel grade during tempering, while tempering determines the performance and life of the workpiece.
A36 is American Standard ASTM material, SS400 is Japanese Standard JIS g3101 steel material for general structure, Q235 is Chinese standard GB700 material. The limitation of the content of the Mn element differs depending on the thickness of the A36 steel plate, and the A36 steel plate of 20 mm or less does not contain Mn. The Hardox 450 steel grade, Q235 steel plate has requirements for the contents of C, Si, Mn, S, P and other elements. But SS400 steel plate only requires S and P to be less than 0.050, and no other element requirements.
