Aerospace Steel Grades & Specifications

Steel plays an important role in the aerospace industries, these quality grades provide numerous properties certified to high standards.

Our range of aerospace specifications are offered in hot rolled and cold rolled bar. Aerospace grades offer a wide range of specific characteristics matching the requirements of the industry. Maraging steel grades offer high strength with good toughness. Alloy steel grades offer high strength and yield with good heat treatment capabilities such as through hardening, nitiriding and case hardening. Stainless steel grades provide good corrosion resistance with some grades suitable for heat treatment.

Grades supplied conform to various national and international standards including British Standard ‘S’ and American AMS grades.
