A242 Type1 Steel Description. 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
ASTM A242 type1 weather resistant steel plate Cu and Cr Cr:chromium can also effectively improve the weather resistance of ASTM A242 type1 weather resistant steel plate, and also can produce solid solution strengthening. However, too high chromium will reduce the toughness and welding performance of ASTM A242 type1 weather resistant steel plate, so the content of it is limited to 0.40-0.60%.
The comparison between ASTM A283 grade C and A36 steel is basically identified through the quantity of manganese in chemical composition as well as carbon equivalent (CEV).. A36 steel CEV = 0.25+0.4/24 = 0.266% and ASTM A283 grade C CEV = 0.24+0.4/24+0.9/6 = 0.406%. As a consequence, the carbon equivalent of ASTM A283 grade C steel is higher than A36 steel.
ASTM G101 - 04(2020) Standard Guide for Estimating the 5.1 In the past, ASTM specifications for low-alloy weathering steels, such as Specifications A242/A242M, A588/A588M, A606/A606M Type 4, A709/A709M Grade 50W, HPS 70W, and 100W, A852/A852M, and A871/A871M stated that the atmospheric corrosion resistance of these steels is approximately two times that of carbon structural steel with copper. A footnote in the specifications stated that

Weathering steels are a family of low carbon steel alloys that were specifically developed to provide higher strength and more importantly eliminate the need to paint to protect against the elements (rain, snow, humidity, sun, salt, etc.). A242 and A588 are the ASTM designations for the two most common types of weathering steel.
