4140 Aircraft Annealed & Cold Finished Alloy - Flats
4140 Aircraft Alloy Bars
This chromium molybdenum alloy is a deep hardening steel used where strength and impact toughness are required. It has high fatigue strength making it suitable for critical stressed applications at normal as well as elevated temperatures. For increased resistance to wear and abrasion, it may be nitrided.
This grade is a quality product melted under the best of steelmaking practices for aircraft quality steels. It is vacuum degassed to meet the magnetic particle inspection standards of AMS 2301.
