Which resists corrosion better stainless steel or titanium?

Stainless steel, isn't. It resists corrosion better than other steels, perhaps, but it will still corrode, especially in certain environments. read more

Like stainless steels, it is dependent upon an oxide film for its corrosion resistance. Therefore, it performs best in oxidizing media such as hot nitric acid. The oxide film formed on titanium is more protective than that on stainless steel, and it often performs well in media that cause pitting and crevice corrosion in the latter (e.g., seawater, wet chlorine, organic chlorides). read more

Steel is corrosive, rusts, stains, and is heavier than titanium. Steel’s density is 7.85 g/cm3, and titanium has 56% that of steel. When compared to steel, titanium has exceptional resistance to a broad range of acids, alkalis, natural waters and industrial chemicals. read more
