Measures to prevent intergranular corrosion and pitting in A-type SS

2026-01-18View Original

Thread Content

Intergranular corrosion: Avoid heating A-type SS in the range of 500–800°C, or perform solution treatment again after heating. Use SS containing sufficient amounts of Ti and Nb, or add a stabilization treatment. Ultra-low carbon or high-purity A-type SS, duplex SS are used. Pitting: SS with a high chromium content, or those containing large amounts of alloying elements such as Mo, N, Si, etc., – duplex SS. High-purity SS is used to improve surface finish. Amorphous corrosion-resistant alloys – eliminating various defects inherent in crystalline alloys (grain boundaries, dislocations, segregation, etc.)
