ASTM A242 Weathering Steel Plate

ASTM A242 steel is a copper chromium alloy steel – this alloy displays a greater level of resistance to atmospheric weathering when compared to other unalloyed steels.

ASTM A242 Introduction:
ASTM A242 is hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.
ASTM A242 steel chemical composition promotes the early formation of an adhering protective layer of rust when exposed to the elements.

ASTM A242 is widely used for bridges, trains, cars, trucks, container, harbor construction, oil platforms and industrial facilities and so on.

ASTM A242 plates are in a variety of sizes and thicknesses, and is available as ex–stock or directly shipped from the mill. As with all our steels, our plates come with mill test certification, stampings and are fully traceable.
