WR50A Atmospheric Corrosion Resisting Structural Steel
Weathering Steel Products Description
WR50A weathering steel sheet is a structural weathering steel, also known as atmospheric corrosion resistant steel. The main alloying elements are chromium, nickel and copper, and phosphorus is added to give it excellent self-protection properties. WR50A weathering steel plate is equivalent to S355J0WP (1.8945) weathering plate in EN 10025 - 5 : 2004 standard.
WR50A weathering metal delivery status:
Hot rolled, cold rolled, normalized, quenched, tempered, thermo-mechanical controlled process (TMCP), electroslag remelting technology, HIC test.
WR50A weathering corten steel application:
WR50A weathered steel plate is a durable and economical structural steel solution that can be used in applications such as steel bridge chimney gas applications and steel sculpture buildings. At the same time, it can also be used in construction, chimneys, manufacturing, trucks, silos, towers, etc.
