Nitralloy 135 Metal Composition

Nitralloy 135 and 135m specialty steel products are manufactured through the nitriding hardening process that creates a high surface hardness and a strong resistance to corrosion; nitriding temperature normally occurs between 900-1100ºF (480-595ºC). The nitralloy is then air cooled after forging to provide the best possible strength and structure.

Moderate hardening austenitizes at 1700-1750ºF (925-955ºC) for ½ hr per inch of cross section and water or oil quench. Water quench is preferred when cross section exceeds 1 inch in thickness.
