ASTM 304LN - EN 1.4311

Essential details
Sufficient nickel content in Incoloy Alloy 925 provides protection against chloride-ion stress-corrosion cracking whilst in conjunction with the added molybdenum and copper resistance to reducing chemicals is enjoyed. Molybdenum additionally aids resistance to pitting and crevice corrosion whilst Chromium offers resistance to oxidizing environments. During heat treatment a strengthening reaction is caused by the addition of titanium and aluminium.

The nickel content is sufficient for protection against chloride-ion stresscorrosion cracking. The nickel, in conjunction with the molybdenum and copper, also gives outstanding resistance to reducing chemicals. The molybdenum aids resistance to pitting and crevice corrosion. The alloy’s chromium content provides resistance to oxidizing environments. The titanium and aluminum additions cause a strengthening reaction during heat treatment.
