Ua ib qho ntawm cov qib stainless hlau nrov tshaj plaws nyob rau hauv kev ua lag luam, SA312 tp304 cov kav dej ua pov thawj los ua ntau yam khoom siv uas tuaj yeem siv thoob plaws ntau yam kev lag luam tseem ceeb. Yog vim li cas rau qib alloy 304 Stainless Steel 304 Pipes tau nrov yog tias nws muaj kev tiv thaiv zoo rau corrosion hauv ntau qhov nruab nrab. Qhov no yog vim muaj cov ntsiab lus ntau dua ntawm chromium siv nyob rau hauv alloying ntawm stainless hlau kav 1.4301.

Stainless hlau 304 yeeb nkab muaj lub zog tensile zoo nrog rau kev ua kom tawv nqaij, txawm tias cov kav dej no tau raug qhov kub thiab txias. Stainless hlau 304 welded yeeb nkab tsis tsuas yog pom zoo rau atmospheric corrosion, tab sis kuj rau cov zaub mov thiab dej haus thiab ntau yam organic thiab inorganic tshuaj. astm a312 tp304 seamless thiab SS 304 ERW yeeb nkab tuaj yeem tiv taus corrosion rau cov lus hais saum toj no, txawm tias nyob hauv nruab nrab oxidizing thiab txo qis ib puag ncig.
