Stainless Steel Square Bar for Industrial and Structural Applications
Stainless steel square bars engineered for industrial strength, machining precision, and structural applications.

Square Bar

Square bar is a solid stainless steel product with a square cross-section, hot rolled or cold drawn to ASTM A276 dimensional tolerances, supplied in 310S and 316 grades etc

310S square bar's high chromium-nickel content gives it strong resistance to oxidation and scaling at sustained high temperatures, making it well suited to furnace and heat-treatment fabrication; 316 square bar combines structural strength with corrosion resistance for general mechanical and chemical-processing components
