ASTM A240 S30116 Stainless Steel Strip Coil Flat Cold Rolled

UNS S30116 Type 301Si ASTM A240 Stainless Steel Precision Stainless Steel Strip 2BA Hard For Springs​ overview

Type 301Si is an austenitic stainless steel capable of attaining very high strengths while maintaining ductility through cold working. It is not hardenable by heat treatment. Type 301Si is non magnetic in the annealed condition and becomes increasingly magnetic when cold worked. 301Si has an increased silicon content over standard 301 and is typically used for "super" high strength applications. The extra silicon allows for even better ductility at high tensile strengths than standard 301. Both are produced to ASTM A666.

FINISHES - STRIP & FOIL

#1 - Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.

#2D - Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process.

# 2B - Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D.

#BA- Bright annealed cold rolled and bright annealed

#CBA- Course bright annealed cold rolled matte finish and bright anneal

#2 - Cold Rolled

#2BA- Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part. Polished - Various grit finish for specific polish finished requirements.
