With the rapid development of economy, there are many kinds of engineering projects, and their development is very fast. However, steel is an essential material in construction engineering. At present, there are many kinds of steel products on the market. In order to ensure the construction quality, the requirements for the strength, quality and corrosion resistance of BV DH32 oil tanker steel, steel are more and more strict.
Since its inception, the company has always adhered to the development policy of "survival with quality, development with products, cooperation with credibility, and service with customers". I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! And sincerely hope to establish a long-term cooperative relationship with them, mutual benefit and common development.
Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This BV DH32 oil tanker steel rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.
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. BV DH32 oil tanker steel, API 2H GR50 steel is used for making hull, offshore oil production platform, platform pipe joint and other structural parts.
