The A709 grade 50W high strength steel plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The A709 grade 50W high strength steel products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.
High-quality alloy steel is made of high-quality carbon structural steel by adding one or several alloying elements (the total mass fraction does not exceed 5%). The alloying elements contained are of different types and contents, and the corresponding properties are also different. High-quality alloy steel is mainly used to manufacture various parts that are larger in size, more complex in shape and difficult to meet performance requirements with high-quality carbon steel. Through proper heat treatment, A709 grade 50W high strength steel, high-quality alloy steel can obtain higher strength and toughness.
Generally, the steel plates for boiler and pressure are divided into categories. A516 gr60 carbon steel plates have a maximum thickness that varies on the capacity. The tensile strength, elongation, yield strength, and hardness are the mechanical properties of these plates. Physical and chemical characteristics of the boiler quality plates A709 grade 50W high strength steel make these a popular choice in the industries. Also, these carbon steel are made up of premium quality raw materials by the use of the latest machinery and are therefore of robust built.
A709 grade 50W high strength steel, Wear-resistant steel plates are easy to overheat, so pay attention to heating temperature and holding time. It is recommended to heat up to 820 degrees for proper insulation. Tempering temperature: 320 degrees, sufficient time. Hardness: 45-48HRC. Good performance. Salt bath NaCl:BaCl=3:7 can be heated at a temperature of 820, time is 30 seconds/mm (mm refers to the effective thickness of the part), oil cooling. Tempering temperature is 280, air furnace time is 2 hours, and nitrate furnace time is 30 minutes.
15CrMoR specification: Thickness: 5mm to 200mm; Width: 1500mm to 3500mm: Length: 3000mm to 27000mmGB/T 713 Standard Specification for boiler and pressure purposes, technical delivery condition and non alloy, alloy steels with specified elevated temperature properties.Third Party Inspection for A709 grade 50W high strength steel: ABS, DNV, BV, GL, CCS, LR, RINA, KR, NK, CE, SGS, IKE, IEI or other quality department."
