304 Stainless Steel Rectangular Bar 0.1875 in x 1.25 in x 84 in

Our review of this 304 stainless steel rectangular bar finds it best suited to fabricators, machine shops, and maintenance teams who need a reliable, corrosion-resistant raw material. The bottom line: this solid, unpolished mill finish bar delivers the familiar strength and chemical resistance of 304 stainless steel in a ready-to-use 84 in length, making it convenient for projects that require full-length stock without custom cutting. The straightforward specification and industry-standard compliance make it a practical choice when consistent material properties and regulatory traceability matter.

Key Features

• 304 stainless alloy: provides high strength and good corrosion resistance for general-purpose and moderately corrosive environments.
• Mill finish surface: the unpolished finish is ideal for downstream machining, welding, or fabrication where a polished appearance is not required.
• Precise dimensions: 0.1875 in thickness and 1.25 in width in a full 84 in length give long, uniform stock for cutting or forming without seams or joints.
• Versatile applications: suitable for uses in food and beverage, architectural trim, and chemical processing where 304 is commonly specified.
• Standards compliance: meets ASTM-A240, ASTM-A480, and ASTM-A666, which supports material acceptance for regulated projects.

Who It's For

This bar is aimed at professional and hobbyist metalworkers who need a reliable, standard-grade stainless steel bar for structural or cosmetic trim, small structural components, or fabrication projects that require corrosion resistance. It is also useful for shops that cut stock to length and want consistent chemistry and mechanical properties across full-length bars.

Those who need a finished, polished appearance right out of the box or specialized alloys with higher corrosion resistance, such as 316, should look elsewhere. Buyers requiring custom milling or custom-length precision finishes will want to factor in additional processing after purchase.

Pros & Cons

Pros

• Reliable corrosion resistance and strength from the widely used 304 stainless alloy.
• Full 84 in length reduces the need for joining or butt welding in longer runs.
• Meets ASTM standards, which eases specification and inspection for projects.
• Mill finish is economical for shops that will machine or finish the part themselves.

Cons

• Unpolished mill finish may require additional finishing for visible architectural or decorative uses.
• 304 is not as corrosion resistant as higher alloys in highly chlorinated or marine environments.

Our Verdict

This 304 stainless steel rectangular bar is a practical, cost-effective choice for fabricators and shops needing long, uniform stock with dependable corrosion resistance and strength. It represents good value when the mill finish is acceptable or when parts will be machined or finished in-house, and its compliance with ASTM standards simplifies specification for industrial and food-grade applications.

Frequently Asked Questions

Is this bar ready for decorative use?
Answer. The bar is supplied in an unpolished mill finish, so it will need grinding, polishing, or other finishing before use in visible decorative applications.

Can this bar be welded and formed?
Answer. Yes; 304 stainless steel is readily weldable and can be formed with standard techniques for stainless alloys, though proper procedures should be followed to avoid distortion.

Is this alloy suitable for food industry applications?
Answer. Yes; 304 stainless is commonly used in the food and beverage industry and the bar meets relevant ASTM specifications for such uses.
