- Caustic Cracking of Austenitic Stainless Steel - Corrosionpedia
Alloys with higher Ni, such as Alloys 20Cb, AL-6XN, 904L, 800 and 825, are more resistant to caustic corrosion and cracking than the 300 series stainless steels In more severe environments, Ni and Ni-based alloys are often specified
- Differences Between the 300 Series Stainless Steels - Penflex
The 300 series austenitic stainless steels are a set of iron-based chromium-nickel alloys designed to resist corrosion This in combination with excellent formability, resistance to wear, and strength at temperature make them common materials of construction within piping systems
- CCC-Compass : A Software Tool for the . . . - Corrosion Clinic
Primarily carbon steel, low-alloy steels, and 400 series SS Carbon steel is the material most commonly used in situations where caustic corrosion is a concern 300 series SS is generally resistant to caustic corrosion until passivity is damaged
- Passivated Stainless Steel: All You Need to Know
Avoid passivating different stainless steel grades, like the 300 and 400 series, together in the same bath This can cause galvanic corrosion, where the less noble metal corrodes faster By following these precautions, the passivation process will be more effective and avoid potential issues
- Caustic Corrosion - an overview | ScienceDirect Topics
Carbon and low alloy steels are vulnerable to caustic corrosion Using austenitic stainless steels (300 series) instead can mitigate but not eliminate the risk of caustic corrosion Experiments have shown that austenitic stainless steels provide good corrosion resistance to NaOH with a concentration of up to 50% and a temperature of around 93 °C
- DESIGN GUIDELINES FOR THE SELECTION AND USE OF STAINLESS STEEL
Austenitic stainless steels (Table 1) containing chromium and nickel are iden-tified as 300 Series types Alloys contain-ing chromium, nickel and manganese are identified as 200 Series types The stain-less steels in the austenitic group have different compositions and properties, but many common characteristics
- The Hendrix Group, Inc. gt; Archive gt; Technical Newsletters . . .
With these alloys, resistance to aggressive (high temperature) caustic solutions increases significantly compared with the 300-series stainless steels Meaningful corrosion resistance data is available for alloy 800, much less for the other alloys listed here; therefore, the discussion on the resistance of this family of alloys will concentrate
