Boiler Quality Plates
The boiler quality and pressure vessel steel plates are primarily intended for use in welded pressure vessels where notch toughness is important
These grades cover a range of tensile strengths from 450 – 620 MPa and this versatility explains much of the specifications popularity.
The common attributes of boiler plates are high strength, efficient low-temperature toughness, high corrosion resistance, high resistance to HIC, SSCC and embrittlement, high creep resistance and durability. Fabricated using best of raw materials and procured from well-known vendors, the boiler quality plates we offer are high in quality and competent in performance products. These plates are widely demanded and used by a large variety of industries.
