According to the European standard EN10025-3:2004, S275NL weldable fine grain structural steel is mainly used to manufacture the plants of factory, the common construction and construction machinery and equipment. For the bound technical terms,steel plate S275NL have to be done low temperature impacting test in rolling process at -50℃ with minimum energy 27J. Other additional requirements such as UT shall be according to EN 10160, and hull structural GL-F36 shipbuilding plate, steel plate S275NL customers can choose the relative classes for Ultrasonic test.
NM400 wear resistant steel plate has a very high mechanical strength; its mechanical properties are 3 to 5 times that of ordinary low alloy steel plates; it can improve the wear resistance of mechanical related parts; therefore improve the service life of machinery; reduce production costs. The surface hardness of the product hull structural GL-F36 shipbuilding plate is usually Reached 360 - 450HB. NM400 wear resistant steel plate is used for processing and manufacturing of wear-resistant and wearing parts for mining and various construction machinery.
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 hull structural GL-F36 shipbuilding plate 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 hull structural GL-F36 shipbuilding plate seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
Our products have perfect after-sales system to protect the interests of customers. At the same time, we can according to hull structural GL-F36 shipbuilding plate customer's requirements, processing requirements, cutting technical requirements, etc., to develop detailed solutions for customers, so as to make customers 100% satisfied. If you have any requirements and needs, please contact us in time.
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel hull structural GL-F36 shipbuilding plate plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
