Isingeniso se-ASTM A106

Isingeniso se-ASTM A106:

1. I-ASTM A106 yezinto ezijwayelekile zaseMelika, kufaka phakathi u-A, u-B, u-C, amamaki amathathu aphelele

 

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

 

 

  1. Ukuhlaziywa kwamakhemikhali
