JISG3103:1987 SB480 boiler and pressure vessel steel is widely used in the manufacture of steam boiler, pressure vessel, high pressure pipeline and other similar structure with steel plate.
Due to absorb a certain amount of pressure and water pressure, and the use of different temperature environment, such as high, medium and low temperature and so on, JISG3103:1987 SB480 boiler and pressure vessel steel genarally can satisfy the more stringent requirements.
In addition to request a certain strength, toughness outside, also requires material uniform to strictly limit the harmful
defect.To serve the interest and the needs of the public, as well as of our clients, BEBON Internaitonal will hold the belief "product quality and service foremost, sincerity and superior quality" forever.
