I-ASTM A106 Isingeniso

Isingeniso se-ASTM A106:

1. I-ASTM A106 yezinto ezijwayelekile zaseMelika, okuhlanganisa u-A, B, C isamba samabanga amathathu

 

Izinga laseMelika IsiShayina esifanayo amandla aqinile
A 20# 330MPa
B Q235 415MPa,
C Q345 485MPa

 

 

  1. Ukuhlaziywa kwamakhemikhali
  ≤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

 

Ibanga elingenhla lihlukaniswa ngu-C no-Mn, bese liza namandla ahlukene okudonsa.
