2HGR50 carburizing steel implements API Spec 2H standard of American Petroleum Institute. CCS, DNV, ABS, GL, LR, BV, Rina, NK and KR certification can be added according to customer requirements. API2HGR50 is suitable for surface carburizing and hardening treatment, with good workability, small deformation and good fatigue resistance. GL-EH 32 car carrier steel, API 2H GR50 steel is used for making hull, offshore oil production platform, platform pipe joint and other structural parts.
Phosphorus is a very harmful element in GL-EH 32 car carrier steel steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of GL-EH 32 car carrier steel steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.
The qualified flat steel has sufficiently high high temperature strength and high temperature plasticity. Therefore, GL-EH 32 car carrier steel flat steel is not only required to have high enough normal temperature and instantaneous high temperature tensile strength and plasticity, but also long-term strength and long-term plasticity to ensure long-term safe work at high temperatures, especially under creep leakage conditions. The product thickness is 8-50mm, width 150-625mm, length 5-15m。
Land transportation inquiry: (RMB fee) it is required to master the kilometers and towing price of major cities; packing price of each port area; customs clearance fee, commodity inspection fee, and animal and plant inspection fee standard. Key information to be clarified after accepting the consignation of the consignor (generally fax): shipping date, number of packages, box type, box quantity, gross weight and volume.
