Width: 1220-4200mm
Length: 5000-18000mm

ASME SA588 Grade B Introduction
ASME SA588 Grade B is a material with high aesthetic value that turns the final product into a unique and exclusive specimen. ASME SA588 Grade B is high-resistance self-passivating alloy containing copper, chrome and phosphorus, characterised by a high resistance to corrosion and to tensile yield; these alloys are self-protective through the formation of a superficial coating that prevents the progressive extending of the corrosion process.The natural oxidation process, when in contact with air, can be accelerated through appropriate oxidising baths.
Thanks to this process, the resulting material will have a porous surface and unique colour features with warm shades of brown and orange, providing it with an antique feel.

What is the difference between A588 Grade B and SA588 Grade B?
Indeed, their mechanical composition and chemical properties are identical and the key difference is the produce standard. ASTM, the American Society for Testing and Materials, produce standards that define limits and parameters on a product’s properties and the methods of testing those properties. ASME, the American Society of Mechanical Engineers, specifies materials to be used in the manufacture and construction of particular items.The correct standard to keep is based on the specific contract or on local laws. The difference between the two standards is less concrete

SA588 Grade B Delivery Condition: Hot Rolled, Cold Rolled, Normalized, Quenched, Tempering, Thermal Mechanical Control Process (TMCP).
