BBN company is one of the most important manufacturers of ASTM A514 structural steel material medium and heavy steel plates for shipbuilding in China. The general strength shipbuilding steel Grades A, B, D, E and higher-strength grade AH32, AH36, DH32, DH36, EH32, EH36 hull structural steel plates produced by heavy steel (specifications: 6-32mm) have been obtained by nine classification society approval certificates Like ABS, CCS, LR, DNV, GL, RINA, and KR.
The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, ASTM A514 structural steel material seamless steel pipes for ships and petroleum cracking ASTM A514 structural steel material steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many ASTM A514 structural steel material products have been exported to the Middle East, India, Southeast Asia and Europe and America.
Flame cutting is a common hot cutting method in modern iron and steel industry. It is also a very important part in the process of iron and ASTM A514 structural steel material steel processing. Flame cutting can cut very thick carbon steel, its cutting range is very wide, can cut 6mm-200mm thick steel plate. In cutting thick and ASTM A514 structural steel material medium plates, flame cutting plays an important role. And with its price advantage, flame cutting has always occupied a certain market share in thin plate cutting also.
Oxygen is a harmful element in ASTM A514 structural steel material steel. With the increase of oxygen content, the strength of ASTM A514 structural steel material steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of ASTM A514 structural steel material steel.
