Recommended Grades: 304, 316L
Surface Finishes: 2B, BA
Reason: Corrosion resistance, easy to clean
Recommended Grade: 316L
Surface Finish: 2B
Reason: Excellent pitting and chloride resistance
Recommended Grades: 304 and 430 for decorative trim; 409L, 430, and 310S for exhaust components
Surface Finishes: BA, HL, 2B
Reason: 304 and 430 stainless steel coils can be slit to custom widths for automotive trim strips and decorative components, while 409L, 430, and 310S are commonly selected for heat-resistant exhaust parts.
Recommended Grades: 304, 316L
Surface Finishes: 2B, HL
Reason: Structural strength and weather resistance
