NITRIDING #3 (135 Modified) Aircraft Hot Rolled Heat Treated Alloy - Rounds

20 Items Available

View Items Compare Items
Nitriding #3 (135 Modified) is a chromium-molybdenum aluminum alloy steel that can be heat treated to develop high core strength and then nitrided to produce extremely high case hardness. This combination of properties is useful when requirements call for high surface hardness for wear and abrasion, for strength and hardness at temperatures up to approximately 1000°F, and for increased fatigue strength and resistance to corrosion.
