We stock thousands of coils of stainless steel with:
I.D.s from 3" (76.20mm) through 24" (609.6mm)
O.D.s to 54" (1371.6mm)
pancake (ribbon winding)
oscillate winding to spools / reels / bunch-coils
tolerances of +/-.0002" (.005 mm) on thickness
tolerances of +/-.0015" (.038 mm) on width
thickness generally starts at .001" (.025mm) and goes thru .250" (6.35mm)
Quality - Our A2LA Certified lab can provide testing to AMS, ASTM, AISI, DIN, JIS, or customer supplied requirements.
AISI, ASTM, MIL-S, QQS, AMS Compliant
Source 21 uses modern rolling techniques to reduce the gauge (thickness) of stainless steel coil sheet to your specifications. Our rolling process produces high quality stainless steel with a consistent gauge to prevent weak spots or deformation.
Additionally, we offer temper rolling of stainless steel coil and strip. When drawn or formed, many steels will exhibit unwanted strain lines. Temper rolling of stainless steel coil and strip is a light pass given to annealed cold rolled strip to prevent the formation of kinks and stretcher strain markings on subsequent cold working. Temper rolling involves a small amount of cold roll reduction as a final operation on annealed material to eliminate stretcher strains. This process is sometimes used to improve the surface finish on a steel product. It is also know as pinch pass and skin pass.
