Intshayelelo ye-ASTM A106

Intshayelelo ye-ASTM A106:

1. I-ASTM A106 yezixhobo ezisemgangathweni zaseMelika, kuquka u-A, u-B, u-C, iiklasi ezintathu zizonke

 

Umgangatho waseMelika IsiTshayina esifanayo tensile strength
A 20# 330MPa
B Q235 415MPa,
C Q345 485MPa

 

 

  1. Uhlalutyo lweekhemikhali
  ≤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

 

Udidi olungaphezulu luphawulwa ngo-C kunye no-Mn, emva koko luza namandla ahlukeneyo okutsalwa.
