General Corrosion Status

No specific corrosion protection required

Corrosion/Thermal

Corrosion resistance is sufficient for most applications, but is inferior to the 300 series stainless steels

Stress Corrosion Status

Moderate Resistance to SCC: Table 2 Remark:Tempering between 371oC and 593oC shall be avoided because corrosion and stress corrosion cracking resistance is lowered. Requires Stress corrosion evaluation form Data Quality: Design Data

EMF vs SCE

-0.17 V Remark:Measured in 3.5% NaCl solution. Passive condition Data Quality: Design Data
