ASTM A242 gr1 steel plate is killed or semi-killed hot rolled structural steel plates with improved atmospheric corrosion resistance. Chemical elements chromium, nickel , copper and phosphorous, all of these elements makes ASTM A242 gr1 steel plate own excellent self protecting qualities. ASTM A242 gr1 steel plate is especially suitable for construction curtain.
With time passing by, ASTM A242 gr1 steel plate itself can form a tight oxidizing layer which can slow down the process of corrosion. In this perspective, ASTM A242 gr1 steel plate is better than many other structural steel plate in many applications.
