15CrMo steel belongs to Pearlite Heat-resistant steel, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperature (generally not more than 600 ℃), and has certain hydrogen corrosion resistance. So GL-DH 36
hull steel plates, 15CrMo steel is widely used in petrochemical industry. However, due to the high content of Cr, C and other alloy elements in the steel, the hardening tendency of 15CrMo steel is obvious and the weldability is poor. The main problems are hardening in heat affected zone, cold cracks and reheat cracks during post weld heat treatment.Our company's GL-DH 36
hull steel plates 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 GL-DH 36 hull steel plates utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This GL-DH 36 hull steel plates method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.The mechanical properties of GL-DH 36 hull steel plates, boiler pressure components steel include strength, plasticity, toughness and fatigue properties. Temperature has a great influence on the mechanical properties of steel. With the increase of temperature, the yield limit of all kinds of steel will monotonically decrease, but the tensile strength will rise to a high peak at a certain temperature, and then decrease.Our company regularly visits customers, consults and follows up the after-sales service, and directly solves problems for customers. In the use of our steel materials, whether quality problems or not, the after-sales will help solve the problem as soon as possible. We promise free life-long replacement for any product quality problems. The sound after-sales service system make you free from worries.
