410L Stainless Steel Corrosion Resistance
Type 410 possesses a high degree of resistance to atmospheric corrosion because of its ability to form a tightly adherent oxide film which protects its surface from further attack.
430L and 434L Stainless Steel Low-carbon ferritic stainless steels, in mildly corrosive environments or atmospheric exposures, have corrosion resistance approaching that of some nickel stainless steels. These alloys are oxidation resistant at elevated temperatures. Types 430 and 434 are ductile and do not work-harden readily.
The toughness -- defined as resistance to crack propagation or notch strength -- of ferritic steels is relatively low, and the ductile-to-brittle transition temperature is at or above room temperature.
The corrosion and oxidation resistances of the ferritic steels are directly related to their chromium content. The 17% Cr 430 and 434 steel have good corrosion resistance to atmospheric conditions.
These alloys are used in a variety of applications where corrosion resistance is more important than strength.

These alloys are resistant to attack in a wide variety of corrosion media.
Ultra 303L Corrosion Resistance
Ultra 303L and standard 303L test specimens, processed as described below with a compaction pressure of 40 tsi, were subjected to total immersion testing in aqueous 5% NaCl solutions at ambient temperature. Test results are shown below.
Ultra 304L Corrosion Resistance
Ultra 304L and standard 304L test specimens, processed as described below with a compaction pressure of 40 tsi, were subjected to total immersion testing in aqueous 5% NaCl solutions at ambient temperature. Test results are shown below.
Ultra 316L Corrosion Resistance
Ultra 316L and standard 316 test specimens, processed as described below with a compaction pressure of 40 tsi, were subjected to ATSM B-117 salt spray testing because the less severe total immersion test used on Ultra 303L and Ultra 304L proved to be ineffective . The results of the salt spray test are shown below.
316L Plus Corrosion Resistance and Green Properties Overview -- 316L Plus Corrosion Resistance
Stainless steels comprise a higher percentage of the powder metallurgy (P/M) market than ever before. This increase results from end users' growing need for maximum corrosion resistance.
Within these pages, we'll show you how some of our stainless steel P/M products have fared in a battery of lab tests. 316L Plus is our most corrosion-resistant stainless steel because it has a higher percentage of Nickel (Ni) and Molybdenum (Mo), as you can see in the chart below, as well as an additive comprised of Copper (Cu), Nickel (Ni) and Tin (Sn).
