Different ASTM steel pipe grades for various chemical compositions(%)
by Na Huang SEOEven for ASTM steel pipe, one of the ERW steel pipe, is various due to the different chemical compositions(%) in the process of production. Today, we would like to make a comparison between ASTM A333 Grade 1, ASTM A333 Grade 3, ASTM A333 Grade 7 and ASTM A333 Grade 9.
From the chart below, we can figure out clear that ASTM steel pipe A333 Grade 1 has special carbon element with 0.30 compared with the others. And for the manganese element, ASTM steel pipe A333 Grade 1 and 3 are different with the rest two kinds of steel pipe. Generally speaking, ASTM steel pipe A333 Grade 7 and 9 have more similarity in chemical compositions. And we all know that chemical compositions would finally lead the various strength taking for steel pipes. We will talk about this topic in next essay.
