Achosion 304 o Rust Dur Di-staen

Mae ïonau clorid yn bresennol yn eang, megis halen, chwys, dŵr môr, awel y môr, pridd, ac ati. Yn yr amgylchedd lle mae ïonau clorid yn bresennol, mae dur di-staen yn cyrydu'n gyflym a hyd yn oed yn rhagori ar ddur carbon isel cyffredin. Mae ïonau clorid yn ffurfio cymhleth gyda Fe mewn elfennau aloi, sy'n lleihau potensial positif Fe, ac yna'n cael ei ocsidio gan yr ocsidydd i gael gwared ar electronau.

Therefore, there are requirements for the use environment of stainless steel, and it is necessary to wipe frequently to remove dust and keep it clean and dry.

316 and 317 stainless steels are molybdenum-containing stainless steels. Molybdenum content in 317 stainless steel is slightly higher than 316 stainless steel. Because 316 stainless steel contains molybdenum, its overall performance is better than 310 and 304 stainless steel. Under high temperature conditions, when the sulfuric acid concentration is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good resistance to chloride attack, so it is usually used in marine environments.
