Amakuru y'ibicuruzwa Ibigize imiti & Ibikoresho bya mashini

Amakuru y'ibicuruzwa

ASTM A709 ni Igipimo gisanzwe cyerekana ibyuma byubaka ibiraro kandi bikubiyemo karubone, imbaraga-nkeya-zivanze, hamwe n'ibyuma bizimya kandi byoroheje bikoreshwa nk'ibyapa byubaka mukubaka ibiraro. Gnee atanga amanota atanu akurikira ya A709; 36, 50, 50W, HPS 50W na HPS 70W. Ibyiciro bitatu byikirere bya 50W, HPS 50W, na HPS 70W bifite ASTM G101 byongerewe ingufu za Atmospheric Corrosion Resistance Index ya ≥6.0.
