6mm 7mm 8mm 10mm 12mm Square Bar

Description

The stainless steel square bars with side lengths of 6mm, 7mm, 8mm, 10mm and 12mm are usually made of stainless steel alloys such as 201, 301, 304, 316, etc. The stainless steel square bars are corrosion-resistant, stain-resistant, and rust-resistant. The square structure gives the product higher strength and uniformity. They are often used in situations where high strength and stability are required.

Application：

Aerospace
Automotive
Medical and gas/oil/oil applications
