What is alloy sensitization? - Rolled Alloys, Inc.
High-temperature solution heat treatment, commonly called solution-annealing, has been used. The alloy is heated to a temperature of about 1950° to 2050°F and then water or air cooled. Another control technique for preventing intergranular corrosion involves incorporating strong carbide formers or stabilizing elements such as niobium or titanium in the stainless steels.Types 410, 420, 425 Mod, and 440Aheat treatment is necessary. The stainless steel alloys shown in the table on Page 3 were heated as sheet samples for 60 minutes per inch of thickness at 1800°F (982°C) for Type 410 and at 1900°F (1038°C) for Types 420, 425 Modified, and 440A, and then air cooled to room temperature. The as-quenched structure of fresh martensite must be tempered toTechnical Data BLUE SHEET - METSERVE347 and Type 348 stainless steels to sensitization and intergranular corrosion is illustrated by data for the Type 321 alloy in the Copper-Copper Sulfate 16% Sulfuric Acid Test (ASTM A262, Practice E) below.
