Technical key points of thickness of steel nm450 production

EN10028-2: 2003 P235GH steel refers to non-alloy and alloy steels with specific high temperature properties. With good plasticity, toughness, cold bending performance and welding performance, EN10028-2 P235GH steel plate and sheets are suitable for the manufacture of nuclear island steel containment, pressure vessels and equipment components. Our company can supply thickness of steel NM450, P235GH boiler plate thickness 8 to 150mm.

In terms of service, our service is a "one-stop" way of working. We have our own thickness of steel NM450 processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as thickness of steel NM450 cutting, welding, drilling, galvanizing, etc., at the lowest cost.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the thickness of steel NM450 steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of thickness of steel NM450 seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.

Alloying elements can strengthen the properties of structural steels. thickness of steel NM450, Alloy structural steel has suitable hardenability. After proper metal heat treatment, the microstructure is uniform sorbite, bainite or very fine pearlite. Therefore, alloy structural steel has higher tensile strength and yield ratio (generally about 0.85), higher toughness and fatigue strength, and lower ductile brittle transition temperature. Alloy structural steel can be used to manufacture machine parts with larger section size.

We are willing to cooperate sincerely with you with high-quality thickness of steel NM450 products and sincere service to expand the market and create brilliant! We will work hard to create a first-class steel company and provide you with faster and more considerate after-sales services! Moreover, our shipbuilding steel plates have been certified by the nine countries' classification societies including DNV, ABC, GL, LR, BV, CCS, RINA, NK, and KR. The quality assurance system has passed ISO9001-2000 standard certification.
