Sensitization and Intergranular Corrosion of a Nozzle Pipe

Summary The failure of the nozzle was the result of sensitization of the stainless steel microstructure and subsequent intergranular corrosion,resulting in deep pitting and through thickness corrosion of the nozzle pipe material.Sensitization of stainless steel refers to the precipitation of chromium carbides on the grain boundaries and occurs at temperatures between approximately 970 and STAINLESS STEELNov 20,2015 intergranular corrosion ssina specialty steel#0183;Steel chemistry is not susceptible to the formation of continuous intergranular carbides that could lead to intergranular corrosion.When a matching weld filler is required,18 Cr-Cb Stainless Steel (No AWS Class) and EC439 Nb wires are often recommended for light gauge high temperature ( intergranular corrosion ssina specialty steelgt;1000 intergranular corrosion ssina specialty steel#176;F) service where thermal cycling is expected.STAINLESS STEELDec 13,2016 intergranular corrosion ssina specialty steel#0183;intergranular corrosion caused by chromium carbide precipitation.HEAT TREATMENT Stainless Steel).Annealing Heat to 1900 2100 intergranular corrosion ssina specialty steel#176;F (1038 1149 intergranular corrosion ssina specialty steel#176;C),then rapidly quench.PROPERTIES COLD WORKING Due to the higher nickel content,these grades work harden at a lower rate than Type 304.In the annealed condition,they exhibit

Intergranular Corrosion An Invisible Attack on Stainless

Unlike many forms of stainless steel corrosion,intergranular corrosion occurs at a microscopic level impacting the very structure of the metal without always showing a sign of attack on the surface..Fortunately,an intergranular attack requires specific circumstances to occur and,in some cases,the damage is reversible.Intergranular Corrosion SSINAIntergranular Attack of Austenitic Stainless Steels.With austenitic stainless steels,intergranular attack is usually the result of chromium carbide precipitation (Cr23C6) at grain boundaries,which produces a narrow zone of chromium depletion at the grain boundary.This condition is termed sensitization and it is shown schematically Figure 2.High Performance Alloys Stainless Steel,Nickel CWI Series Stainless 439 is a ferritic stainless steel designed to resist corrosion in a variety of oxidizing environments from fresh water to boiling acids.It may be used in either the annealed,cold formed or as-welded condition in many applications where other stainless steel alloys such as Type 304,Type 410,Type 409 and Type 430are used.

Corrosion Types and Prevention - Different Types Of

Intergranular corrosion occurs along or adjacent to these grains,seriously affecting the mechanical properties of the metal while the bulk of the metal remain intact.An example of intergranular corrosion is carbide precipitation,a chemical reaction that can occur when a metal is subjected to very high temperatures (e.g.,800 intergranular corrosion ssina specialty steel#176;F - 1650 intergranular corrosion ssina specialty steel#176;F Corrosion Resistant Metals Materials Selection Guide For Fighting General Corrosion; Localized Corrosion; Stress Corrosion Cracking; Sour Gas Cracking .Alloy C-276 Nickel Alloys.Alloy C-276 (Hastelloy intergranular corrosion ssina specialty steelC-276) contains nickel,molybdenum,and chromium.Its high molybdenum content makes it exceptionally resistant to pitting and crevice corrosion,and it is one of only a few materials that can withstand the corrosive effects of wet chlorine Corrosion SSINA - SSINA Specialty Steel Industry General corrosion of stainless steel occurs when there is a widespread breakdown of the protective passive film allowing the entire surface to The Specialty Steel Industry of North America (SSINA) and the individual companies it represents have made every effort to ensure that the information presented in this website is technically correct
