ASTM A36 carbon low alloy steel plate/sheet

ASTM A36 steel is kind of carbon steel plate, so it’s not a expensive material which have very good performance and strengths to bear the various kind of system pressure. With high durability and even over period it could be recycled totally. Back to furnace and to make fresh steel products.

ASTM A36 carbon low alloy steel is generally available in the many forms i.e. it is available in rectangle bar, square bar, circular bar and also steel shapes like angles, H-beams, I-beams, and channels.

Heat treatment methods and performances for A36 steel plate:
ASTM A36 steel plate is subjected to the normalization treatment at 899°C to 954°C that is at 1650°F to 1750°F, to annealing treatment at 843°C to 871°C that is at 1550°F to 1600°F, to stress relieving process at 677°C to 927°C that is at 1250°F to 1700°F, to carburizing process at 899°C to 927°C that is 1650°F to 1700°F and to hardening process at 788°C to 816°C that is 1450°F to 1500°F. Hardening process is strongly required when hardness and strength are the desired prime properties in design. Normalization treatment is done as the final treatment after the manufacturing process.

Chemical composition of ASTM A36 steel plate:
Carbon (C) content 0.25 – 0.29%,
Copper (Cu) content 0.20%,
Iron (Fe) content 98.0 percentage,
Manganese (Mn) content 1.03 percentage,
Phosphorus (P) content 0.04 percentage,
Silicon (Si) content 0.280 percentage,
Sulfur (S) content 0.050 percentage.
