ASTM A106 Taw qhia

ASTM A106 Kev taw qhia:

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

 

American txuj Zoo sib xws Suav tensile zog
A 20# 330 MPa
B q235 ua 415MPa,
C q345 ua 485MPa ua

 

 

  1. Tshuaj ntsuam xyuas
  ≤C Mn ≤P ≤S Si ≤Cr ≤Cu Mo Ni V
A 0.25 0.27-0.93 Nws 0.035 ib 0.035 ib 0.1 0.4 0.4 0.15 0.4 0.08 ib
B 0.30 Nws 0.29-1.06 Nws 0.035 ib 0.035 ib 0.1 0.4 0.4 0.15 0.4 0.08 ib
C 0.35 Nws 0.29-1.06 Nws 0.035 ib 0.035 ib 0.1 0.4 0.4 0.15 0.4 0.08 ib

 

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