ATI Allegheny Ludlum Stainless Steel Type 301, 1/2 Hard (UNS S30100)
Categories:	Metal; Ferrous Metal; Stainless Steel; T 300 Series Stainless Steel
Material Notes:	Allegheny Ludlum Type 301 is a high strength grade of steel available in six conditions or tempers, its resistance to atmosphere corrosion and its bright, attractive surface make it an excellent choice for decorative structural applications. Applications include automobile molding and trim, wheel cover, conveyor belts, kitchen equipment, roof draining systems, hose clamps, springs, truck and trailer bodies, railway and subway cars. By varying the chemical composition within the limits set by the ASTM Specifications and by temper rolling, a broad range of magnetic and mechanical properties can be obtained for a variety of applications. Information provided by Allegheny Ludlum Corporation.
Key Words:	ASTM A240; ASTM A666
