EN10028-2 P295GH plate with elevated temperature property gives optimum performance for pressurized products that must support a creep limit greater than 155N/mm2 at 400ºC. RINA EH40 hull structural ship plate, P295GH plate is a normalized steel and has excellent welding characteristics. P295GH plates and sheets are used worldwide by fabricators serving the oil and gas industry and can be found in heat exchangers, weldable pressure vessels and boilers and pipework.
The company attaches great importance to systematic management, and has passed the RINA EH40 hull structural ship plate ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on RINA EH40 hull structural ship plate quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the RINA EH40 hull structural ship plate product workpiece, thereby improving the production efficiency and production processing quality.
Vanadium mainly exists in the form of carbide in RINA EH40 hull structural ship plate and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
