316 Stainless Steel Square Bar offers outstanding strength, excellent corrosion resistance, and superior durability, making it an ideal choice for demanding industrial applications. As a marine grade stainless steel square bar, Grade 316 provides better resistance to chloride corrosion than 304 stainless steel, making it well suited for marine and coastal environments.
Manufactured in accordance with ASTM A276, 316 Stainless Steel Square Bar and 316L Stainless Steel Square Bar maintain excellent mechanical properties at both cryogenic and elevated temperatures while delivering reliable weldability and machinability. Cold Drawn Stainless Steel Square Bar also provides improved dimensional accuracy, tighter tolerances, and a smooth bright surface finish for precision engineering applications.
These stainless steel square bars are widely used in oil and gas equipment, petroleum processing, aerospace components, food processing machinery, pulp and paper production, textile machinery, architectural fabrication, chemical processing equipment, marine engineering, offshore platforms, pumps, valves, and precision CNC machining, where high strength, corrosion resistance, and long service life are essential.

316 & 316L Stainless Steel Square Bar Applications
Marine Engineering
316 & 316L Stainless Steel Square Bars are widely used in marine hardware, offshore platforms, shipbuilding, seawater piping supports, and coastal infrastructure because of their excellent resistance to chloride corrosion.
Chemical Processing Equipment
Suitable for pressure vessels, heat exchangers, reactors, pumps, valves, pipe supports, storage tanks, and other equipment operating in corrosive environments.
Food & Beverage Processing
Ideal for food-grade machinery, conveyor systems, mixing equipment, packaging machines, and processing lines that require hygienic and corrosion-resistant materials.
Pharmaceutical & Medical Equipment
Used in pharmaceutical processing systems, laboratory equipment, cleanroom installations, and medical machinery due to their excellent cleanability and corrosion resistance.
CNC Machining & Precision Engineering
The high dimensional accuracy of cold drawn square bars makes them suitable for precision-machined components, fixtures, tooling, shafts, molds, automation equipment, and custom-engineered parts.
What is ASTM A276 316 & 316L Stainless Steel Square Bar?
It is a solid square stainless steel bar manufactured according to ASTM A276. Grades 316 and 316L are widely used in industries requiring excellent corrosion resistance, strength, and machinability.
What is the difference between 316 and 316L?
316L contains a lower carbon content (maximum 0.03%), which improves weldability and reduces the risk of carbide precipitation during welding. It is generally preferred for welded structures and highly corrosive environments.
Is 1/2 Inch Stainless Steel Square Bar available in stock?
Yes. The 1/2 Inch (12.7 × 12.7 mm) size is one of our standard inventory products. Other sizes and custom dimensions are also available.
What surface finish do you offer?
The standard finish is Bright Cold Drawn. Ground, polished, and brushed finishes are available upon request.
Can you provide EN 10204 3.1 certificates?
Yes. We provide EN 10204 3.1 Mill Test Certificates, material traceability documents, and optional third-party inspection reports.
