ASTM A106 Introduction

ASTM A106 introduction:

1. ASTM A106 for the American standard material, including A, B, C a total of three grades

 

American standard Similar Chinese tensile strength
A 20# 330MPa
B Q235 415MPa,
C Q345 485MPa

  ≤C Mn ≤P ≤S Si ≤Cr ≤Cu Mo Ni V
A 0.25 0.27-0.93 0.035 0.035 0.1 0.4 0.4 0.15 0.4 0.08
B 0.30 0.29-1.06 0.035 0.035 0.1 0.4 0.4 0.15 0.4 0.08
C 0.35 0.29-1.06 0.035 0.035 0.1 0.4 0.4 0.15 0.4 0.08

 

Above grade is distinguished by C and Mn, then it come with different tensile strength.
