Application of ASTM A106 Gr B seamless steel pipes:

ASTM A106 seamless  steel pipe (also known as ASME SA106 Pipe) is commonly used in the construction of oil and gas refineries,power plants,petrochemical plants, boilers, and ships where the piping must transport fluids and gasses that exhibit higher temperatures and pressure levels.

Chemical Composition ASTM A106 carbon steel seamless pipes:

Chemical Composition Grade A Grade B Grade C
Carbon max. % 0.25 0.30 0.35
Manganese % 0.27 to 0.93 0.29 to 1.06 0.29 to 1.06
Phosphorous, max. % 0.035 0.035 0.035
Sulfur, max. % 0.035 0.035 0.035
Silicon, min.% 0.10 0.10 0.10
Chrome, max. % 0.40 0.40 0.40
Copper, max. % 0.40 0.40 0.40
Molybdenum, max. % 0.15 0.15 0.15
Nickel, max. % 0.40 0.40 0.40
Vanadium, min.% 0.08 0.08 0.08

Notes:

  • Total of Cr, Cu, Mo, Ni, and V shall not exceed 1%;
  • If the carbon content is lower than the stipulated maximum carbon content, the content of manganese in A106 seamless steel tube can be increased by 0.06% above the stipulated maximum manganese content for every 0.01% reduction of carbon content, but the maximum content shall not exceed 1.35%.
