A242 Type1 Resistant to atmospherical corrosion steel plate is the Equivalent grades as S355J2WP (1.8946) steel in EN 10025 - 5 : 2004 standard and FE510D1K1 steel in UNI standard and also E36WA4 steel in NFA 35-502 standard. A242 Type 1 steel plate is a commonly used product in bridge construction because of the lack of maintenance costs. A242 Type 1 Resistant to atmospherical corrosion is also popular in modern architecture where the aesthetically pleasing finish is in great demand for sculptural buildings and fascias.
A242 Type1 steel grade is a hot rolled products of structural steels in technical delivery conditions with improved atmospheric corrosion resistance.The main alloying elements are chromium nickel and copper with added phosphorous which gives it excellent self protecting qualities. As the steel reacts with elements in the atmosphere, the material forms a layer of rust over time which in essence protects the steel from corrosion.
