1. Introduction o Q315NS acid-pale kila:
Kaumaha: Q315NS
Ka inoa o ka huahana: Sulfuric acid kūpaʻa kila no ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa dew point corrosion
Kūlana hoʻokō: GB/T28907-2012
ʻO ka nui, ke ʻano, ke kaumaha a me ka ʻae ʻia o Q315NS e hoʻokō me GB/T709.

2. Wehewehe o Q315NS acid-resistant steel:
Q315NS kaʻina hōʻike: Q-ka hua mua o ka pinyin Kina o "qu" i ka ikaika hua;315—ka palena haahaa o ke kila, ma MPa;NS—ka hua mua o ka pinyin Kina o ka "kū'ē" a me ka "acid".ʻO ka Q315NS acid-resistant steel e pili ana i ka hoʻohui ʻana i kekahi mau mea hoʻohui i ke kila e hoʻonui ai i ke kūʻē ʻana i ka sulfuric acid i hana ʻia e ka hui ʻana o ka sulfur trioxide a me ka wai ma lalo o ka hau i ka wā e ʻike ʻia ai ke kila i ke kinoea sulfuric (e like me ka ke kapuahi kila i loko o ke kinoea hoʻopau).Hana ʻino.

3. ʻO ke kila kila o Q315NS acid-resistant steel:
Material CSiMnPSCrCuSbQ345NS≤0.15≤0.55≤1.20≤0.035≤0.0350.30-1.200.20-0.50≤0.15

4. Mechanical waiwai o Q315NS acid-kūpaʻa kila: mea hua ikaika Ra MPa tensile ikaika Ra MPa elongation ma hope o ka haʻihaʻi A%Q315NS≥315≥440≥22Q345NS≥345≥470≥20

5. Ke kū'ē'āhewa o Q315NS acid-kūpaʻa kila:
Wahi a ke ʻano hoʻāʻo i ʻōlelo ʻia ma JB/T7901, ʻaʻole ʻoi aku ka nui o ka corrosion ma mua o 10mm/a (0.89mg/cm²*h, 30% pili i ka helu corrosion o Q235B ma lalo o nā kūlana o kahi mahana o 20 ℃, he sulfuric. ka nui o ka waika 20%, a me ka piha piha no 24 mau hola);Ma lalo o ke kūlana o ka mahana 70 ℃ a me ka piha piha no 24h, ʻaʻole ʻoi aku ka nui o ka corrosion ma mua o 250mm/a (22.4mg/cm²*h, 50% pili i ka helu corrosion Q235B).
