Specialty steels and other iron alloys have specialized or proprietary compositions or properties. They include stainless steel, nickel and cobalt alloys, superalloys, titanium alloys, tungsten materials, and high-temperature and corrosion-resistant metals for aerospace, medical, automotive, and energy applications. Super alloys have very diverse chemical compositions and properties. These specialty steels and other iron alloys can perform under exceedingly rigorous service conditions. They also have good electrical, thermal, and magnetic properties. Like other specialty steels and other iron alloys, supper alloys can be modified to meet application requirements. Suppliers of specialty steel or alloy steel may provide a range of products, or serve particular industries.
