ASTM A106 Kev Taw Qhia

ASTM A106 kev taw qhia:

1. ASTM A106 rau cov khoom siv txheem Asmeskas, suav nrog A, B, C tag nrho peb qib

 

Tus qauv Asmeskas Suav zoo sib xws lub zog tensile
A 20# 330MPa
B Q235 415MPa,
C Q345 485MPa

 

 

  1. Tshuaj ntsuam xyuas tshuaj lom neeg
  ≤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

 

Qib saum toj no yog qhov sib txawv los ntawm C thiab Mn, tom qab ntawd nws tuaj nrog lub zog tensile sib txawv.
