Which steel has the highest corrosion resistance?

Austenitic steels, which contain 16 to 26 percent chromium and up to 35 percent nickel, usually have the highest corrosion resistance. They are not hardenable by heat treatment and are nonmagnetic. The most common type is the 18/8, or 304, grade, which contains 18 percent chromium and 8 percent nickel.

Is stainless steel corrosion resistant?

Stainless steels are iron-based alloys with a minimum of 10.5% chromium. The more chromium, the more corrosion resistance. Over time, corrosion can form in crevices. Surface pitting can also develop, but this can take years to happen, depending on the grade.

What is the best grade of stainless steel?

The best known grade is Type 304, also known as 18/8 and 18/10 for its composition of 18% chromium and 8%/10% nickel, respectively. The second most common austenitic stainless steel is Type 316. The addition of 2% molybdenum provides greater resistance to acids and to localized corrosion caused by chloride ions.
