Austenitic stainless steels are susceptible to microbiologically influenced corrosion (MIC) when it is used in contact with natural waters. This is due to the changes in the chemistry of the environment at the metal surface because of the settlement and activities of microorganisms. The corrosion resistance of all stainless steels also improves if they are kept clean. The build up of salt encrustations, grease or dirt allows corrosion to occur in these regions. After use in marine situations, it is good practice to wash down with clean water and to remove any deposits on the surface.

Abstract. The corrosion resistance of high-strength Cr–Ni–Mn austenitic steel containing nitrogen and copper is compared with that of Cr18Ni9 and Cr18Ni10N chromonickel steel by means of the Zive MP2 electrochemical by: 1. Graphite in any form should never be used in contact with stainless steels in brackish or sea water. Carbon filled rubber O rings and gaskets are widely used in contact with stainless steels in sea water. The corrosion that occurs under O rings and black rubber gaskets is normally crevice corrosion. There are many types of austenitic stainless steels—most of them originate from type , which is the 18Cr–8Ni stainless steel. Type L has its corrosion resistance improved by adding molybdenum and reducing carbon. Type L is the most popular form of stainless steel used in medical application due to its high corrosion resistance. enhance corrosion resistance and in some cases to meet mechanical properties. Minimum heat-treat temperatures are specified; however, it is 1 This specification is under the jurisdiction of ASTM Committee A-1 on Steel, Stainless Steel, and Related Alloysand is the direct responsibility of Subcommittee A on Size: 63KB.

Stainless steels and specialty alloys for pulp, paper and biomass conversion mills. higher content of silicon ( – % Si) that gave more rapid corrosion rates. The zone of most severe corrosion in a batch digester varies from mill to mill, and sometimes from digester to digester within the same mill. Austenitic stainless steels, as a class, have excellent corrosion resistance and those with molybdenum additions have improved pitting resistance. The nickel content in austenitic stainless steels helps to reduce the rate of corrosion, particularly in acid environments. He discusses the corrosion-resistant characteristics of austenitic, ferritic, duplex, martensitic, and precipitation hardening stainless steels and devotes several chapters to localized forms of corrosion such as pitting, crevice corrosion, and stress corrosion by: high hardness and corrosion resistance, providing an optimal solution for many applications. Sustainable stainless steels Martensitic stainless steels typically contain 12 to 17% chromium and nickel in a range from 0 to 5%. The lower nickel content (compared to austenitic stainless steels) offers the secondary advantage of a lower material cost.
