API2HGr50 delivery status: steel is usually delivered in hot rolled or hot forged state. It can also be delivered in the state of heat treatment (annealing, normalizing or high temperature tempering). Annealing: The steel RINA FH36 ocean engineering steel is heated to a suitable temperature and slowly cooled according to the heating time of different materials and specifications. Normalizing: Heat the steel plate to a suitable temperature and cool it in the air. Tempering: Keep the steel plate at an appropriate temperature for a long time while keeping it cool.
The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy RINA FH36 ocean engineering steel products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of RINA FH36 ocean engineering steel stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.
First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of RINA FH36 ocean engineering steel welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.
Alloying elements can strengthen the properties of structural steels. RINA FH36 ocean engineering steel, Alloy structural steel has suitable hardenability. After proper metal heat treatment, the microstructure is uniform sorbite, bainite or very fine pearlite. Therefore, alloy structural steel has higher tensile strength and yield ratio (generally about 0.85), higher toughness and fatigue strength, and lower ductile brittle transition temperature. Alloy structural steel can be used to manufacture machine parts with larger section size.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality RINA FH36 ocean engineering steel products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
