Main Application

These products have good comprehensive mechanical property, weldability and processing property. They are used to manufacture hull structure of oceangoing, costal and in-land water ships, as well as structural members of boatyard, costal and offshore oil platform, FPSO ship, Spar platform, transportation pipeline in sea, costal power plant, port facilities, etc. API 2H/2W series products are mainly use to fabricate welding structural members of costal service, such as pipe joint, ribbed plate structure and other connecting parts. Marine platforms in USA and Gulf of Mexico generally adopt equivalent steel plates as per API standards. Therefore, these products are targeted to domestic and foreign shipyards and marine engineering equipment manufacturers, and their supporting enterprises
