SB480M Steel Plate SB480M Hot Rolled Steel Sheet SB480M Hot Rolled Steel Plates
SB480M is mainly used for building pressure vessels.The minimum yield strength of SB480M shall be above 275Mpa,and tensile strength of SB480M shall be within 480-620Mpa.For boiler steel plate SB480M with thickness exceeding 38mm shall be normalized when rolling,and belows or equal to 38mm thickness,as rolled is ok.

Corrosion resistant-
it is known that corrosion is natural and it converts refined metal into chemically stable form like hydroxide, oxide, and sulfide. The boiler quality plates are made in such a way that the corrosion field can be stopped or controlled. The corrosion engineering helps in overcoming corrosions like stress corrosion cracking, crevice corrosion and pitting corrosion.
Offer in extensive array-
the boiler quality plates are offered an extensive array this implies that they are manufactured with different specification, dimensions, finish, and forms.
Mandatory treatment and testing-
Heat treatment-
the boiler quality plates can be normalized as it has fine grain quality. Liquid quenching is done through accelerated cooling.
Impact testing-
as per the S5 specification at (-30) degree Charpy “V” notch test is conducted for all heat number of plates. It can be conducted after simulation of heat treatment for boiler quality plates.
Tolerance-
it is defined that there would be no negative tolerance in plate thickness. The tolerance in width and length could be as per the SA20. The tolerance in plate width would be uniform across the length.
