| Stress Corrosion Status | High Resistance to SCC: Table 1: UTS below 125 kg/mm2
A small number of laboratory failures of specimens cut from plate more than 2 inches thick have been observed at 75% yield, even within this ultimate strength range. The use of thick plate should therefore be avoided in a corrosive environment when sustained tensile stress in the short transverse direction is expected.
Moderate Resistance to SCC: Table 2: UTS 125 to 140 kg/mm2 UTS
Remark: Requires Stress corrosion evaluation form
Low Resistance to SCC: Table 3: UTS above 140 kg/mm2 UTS
Remark: Not for primary structural items
Remark: Requires Stress corrosion evaluation form
Remark: acc. to ECSS-Q-ST-70-36C
