AMS 5517 is a professional aerospace and industrial specification governing corrosion-resistant 301 1/4 Hard stainless steel sheet and coil (UNS S30100). This standard covers cold-rolled stainless steel sheets and strips with a minimum nominal thickness of 0.005 inch (0.13 mm), widely adopted for precision forming, structural components and medium-strength industrial parts. As a reliable China premium stainless steel supplier,ZYTC Alloy provides fully compliant AMS 5517 301 1/4 Hard stainless steel sheets and coils with stable temper consistency, precise dimensional tolerance and excellent surface quality. 301 1/4 Hard is a lightly cold-worked temper grade in the 301 stainless steel family, featuring a perfect balance of enhanced mechanical strength and outstanding formability. It fills the performance gap between soft annealed 301 and high-hardness 1/2 Hard / Full Hard grades, becoming one of the most versatile and cost-effective tempers for general and precision industrial manufacturing. 
Specifications & Physical Data301-1/4 Hard stainless steel is an austenitic grade with nominal composition of 17% chromium and 7% nickel . Its mechanical properties are achieved through cold working—not heat treatment—making it a work-hardened material rather than a heat-treatable alloy. Available Forms: Sheet, strip, coil (0.005″ and over) Specifications: To meet different strength and forming requirements, ZYTC Alloy supplies full-series 301 stainless steel tempers with complete AMS standard compliance: AMS 5901 (301 Annealed): Min 75ksi tensile strength, soft temper for complex deep drawing AMS 5518 (301 1/2 Hard): Min 150ksi tensile strength, medium-high strength for structural parts AMS 5902 (301 3/4 Hard): Min 175ksi tensile strength, high strength for load-bearing components AMS 5519 (301 Full Hard): Min 185ksi tensile strength, ultra-high strength for elastic and wear-resistant parts
