  1. What is Steel Corrosion? - Definition from Corrosionpedia

    The rate of steel corrosion is affected by factors such as ambient air temperature, presence of chemical fumes and vapors, as well as humidity. In the case of buried steel structures and pipes, the composition of the soil and its moisture influence the extent of corrosion and its impact.

  2. Corrosion of structural steel - SteelConstruction.info

    The corrosion of structural steel is an electrochemical process that requires the simultaneous presence of moisture and oxygen. Essentially, the iron in the steel is oxidised to produce rust, which occupies approximately six times the volume of the original material.

  3. Corrosion - Wikipedia

    Corrosion on exposed metal, including a bolt and nut. Side view Crow Hall Railway Bridge north of Preston Lancs corroding general. Corrosion is a natural process that converts a refined metal into a more chemically-stable form such as oxide, hydroxide, or sulfide.

  4. What forms of corrosion can occur in stainless steels?

    The most common forms of corrosion in stainless steel are: Pitting corrosion - The passive layer on stainless steel can be attacked by certain chemical species. The chloride ion Cl- is the most common of these and is found in everyday materials such as salt and bleach.

  5. Corrosion Rate | American Galvanizers Association

    Corrosion of carbon steel occurs when the relative humidity of the air is 70% to 80% and the air temperature is above 32 F. Corrosion rates may be accelerated by air impurities that dissolve in condensed water or rain water and by dust and dirt settling on the metal surface.

  7. What Causes Corrosion? - CSL Silicones

    How Corrosion Occurs. Corrosion is an electrochemical reaction that appears in several forms, such as chemical corrosion and atmospheric corrosion, the latter of which is the most common form. When acidic substances (including water) come in contact with metals, such as iron and/or steel, rust begins to form.

  8. Steel Corrosion | American Galvanizers Association

    The corrosion process that takes place on a piece of uncoated steel is very complex. Factors such as variations in the composition/structure of the steel, presence of impurities due to the higher instance of recycled steel, uneven internal stress, and/or exposure to non-uniform environment all affect the corrosion process.

  10. SSINA: Stainless Steel: Corrosion

    The duplex stainless steel with their dual austenite/ferrite microstructures has a resistance that is in between that of the austenite and ferrite grades. Corrosion Testing. The relative resistance of a stainless steel to chloride SCC is often quantified by the use of standard boiling salt solutions.

  11. Pitting corrosion - facts and how to reduce the risk q460e steel corrosion

    Problems with pitting corrosion attacks depend primarily on the chloride content, the pH value (the acidity), and the temperature. If pitting has taken place and if the environment in such is not too corrosive for the steel grade, a spontaneous repair of the passive layer will occur in the presence of oxygen.

  12. Galvanic corrosion - facts and how to reduce the risk q460e steel corrosion

    If two stainless steel grades of similar type are galvanically coupled, there is usually no risk of galvanic corrosion. However, if corrosion occurs for some reason in one of the stainless steels, the active steel corrodes with a higher corrosion rate than usual, driven by the difference in potential between the active and passive states.

  13. Chloride stress corrosion cracking in austenitic stainless steel

    Chloride stress corrosion cracking (CLSCC) is one the most common reasons why austenitic stainless steel pipework and vessels deteriorate in the chemical processing and petrochemical industries. Deterioration by CLSCC can lead to failures that have the potential to release stored energy and/or hazardous substances.

  14. Chloride attack on Stainless Steel - N.E.M

    The following picture shows severe corrosion in a 304L stainless steel tube that carried water used for cooking cheese. The salt in the cheese leached into the water, creating an ideal environment for corrosion. Chloride Attack on Stainless Steels. Chloride-induced corrosion is not bulk corrosion.


    Strong acid corrosion of carbon steel involves reaction between iron and hydrogen ions and hence is dependent largely on pH. CO 2 corrosion involves a similar reaction but also reaction with carbonic acid so that it is not pH alone which determines corrosion rate. the

  16. A comparative H2S corrosion study of 304L and q460e steel corrosion - ScienceDirect

    In this paper, EIS measurements in conjunction with open circuit potential (OCP), linear polarisation resistance (LPR), and potentiodynamic polarisation (PD) tests and surface microstructural characterization were performed to investigate the H 2 S corrosion of 304L and 316L stainless steels in acidic media at 0, 5 and 15 ppm (by mole q460e steel corrosion

  17. Stainless Steel - Corrosion Resistance

    Corrosion resistance is one of the main advantages of the application of stainless steels. However, in some cases, stainless steels suffer certain types of corrosion and therefore precautions should be taken in choosing a suitable steel grade for any application. Based on the applications, corrosion q460e steel corrosion

  18. Chloride corrosion of carbon steel pipe - Engineering Stack q460e steel corrosion

    I am specifying pipes for a water system with 500 ppm chloride in solution. Ordinarily we would specify 316L stainless steel to limit the corrosion, but I was asked if we could instead specify carbon steel pipe with a corrosion allowance. So instead of the typical schedule 40 pipe, could I realistically use schedule 80 or 120 etc?

    Corrosion rates in the splash zone are similar to the low water level, i.e. 0.075mm/year/side. In this zone thick stratified rust layers can develop, however, it should be borne in mind that rust has a much greater volume than the steel from which it is derived and steel corrosion losses may amount to no more than 10% to 20% of the rust thickness.

  25. Article: Corrosion mechanisms in stainless steel

    General corrosion is much less severe in stainless steel than in other steels. It only occurs when the stainless steel is at a pH value < 1.0. Reference should be made to tables in manufacturers' literature, or the advice of a corrosion engineer should be sought, if the stainless steel is to come into contact with chemicals.
