Nyob rau hauv muaj pes tsawg leeg ntawm St {{0}} Galvanized Seamless Yeeb Nkab, carbon yog lub ntsiab tseem ceeb, feem ntau yog accounting rau 0.12% rau 0.20% ntawm tag nrho cov muaj pes tsawg leeg. Silicon thiab manganese kuj tseem yog cov ntsiab lus tseem ceeb, feem ntau nyob rau hauv cov nyiaj ntawm 0.10% mus rau 0.40% txhua. Cov ntsiab lus phosphorus thiab sulfur yog tswj nyob rau theem qis kom tswj tau zoo toughness thiab corrosion kuj.
St37-2 galvanized steel yeeb nkab muaj lub zog tensile siab thiab lub zog tawm los thiab tuaj yeem ua tau raws li qhov yuav tsum tau muaj zog ntawm ntau yam khoom siv tshuab. Nws lub zog tensile feem ntau yog nyob nruab nrab ntawm 135 thiab 165N / mm², thiab nws lub zog tawm los ntawm 110 thiab 130N / mm². Qhov no ua rau St37-2 kub-dip galvanized steel yeeb nkab los tiv thaiv lub siab ntawm cov khoom thauj thiab xyuas kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov khoom siv tshuab.
St37-2 Galvanized kav dej muaj cov yas zoo thiab tawv, thiab tuaj yeem siv rau kev khoov, ncab, cuam tshuam thiab lwm yam kev ua haujlwm yam tsis tas yuav ua rau tawg tawg. Qhov no ua rau St37-2 Galvanized piping hloov mus rau cov txheej txheem ua haujlwm ntawm ntau yam duab thiab tsim cov khoom siv nrog cov duab nyuaj.
