ASTM A423/ A423M standard contains three grades which are Grade 1, Grade 2, Grade 3, determines minimum-wall-thickness, seamless and electric- resistance [TJC STEEL]welded, low-alloy steel tubes for pressure containing parts such as economizers or other applications where corrosion resistance is important.
Seamless or Welded Pipes/ Tubes’ sizes and thicknesses under standard of ASTM A423/ A423M are 12.7 to 127mm( outside diameter) and 0.9 to 12.7mm( thickness). When seamless type, the producing process would be hot finished or cold finished. [TJC STEEL]Heat treatment would be Normalized or other relevant heat treatments necessary to conform purchasing requirements.
