Metallurgical Tests Performed on Flat Rolled Stainless Steel and Aluminum

 
Tensile – ASTM E8

Test includes tensile, yield and elongation (specify test direction). Thickness range annealed and tempered – 0.006″ to 0.187” Per: ASTM E8 (steels); AST M B557 (aluminum)

 
Rockwell Hardness Testing – ASTM E18

ASTM E18. Rockwell A, B and C and Rockwell Superficial T and N scales. Test includes average of 3 reading – conversions per ASTM E140. Thickness minimum annealed and tempered – 0.010″.

 
Bend – ASTM E290

ASTM E290: • Testing conducted with the bend parallel or perpendicular to rolling direction (specify test direction). 180 Degree bend thickness maximum (annealed 0.150″, tempered 0.050″).

 
Surface Finish Testing – ASME B46.1:

ASME B46.1:

• Ra, Rz, Rq – Please specify test direction. No thickness restrictions – sample must be flat.
• Chemistry (200, 300 & 400 series stainless steels) Per ASTM A751 and ASTM E1086
• Chemistry (1000, 2000, 3000, 5000, 6000 & 7000 series Aluminums) Per ASTM E1251
• Chemical analysis is performed using optical emission spectroscopy (OES).
• Let us advise you on your electrical steel core loss, coating composition and coating resistance requirements.
