BS WR 50 C steel plate, WR 50 C steel plate, under BS 4360standard, we can regard BS 4360 WR 50 C steel plate as Steel Resistant to Atmospherical Corrosion
WR 50 C steel plate is one mainly of Steel Resistant to Atmospherical Corrosion, WR 50 C steel plate is a weather-resistant structural steel with mechanical properties similar to WR 50 C. By adding Cr, Cu and Ni, it formed oxide layers stick firmly to the work piece surface. This oxide layer prevents further corrosion of the steel.
