A stainless steel round (bar) is a solid, cylindrical metal bar or rod. It is typically characterized by its uniform diameter throughout its length. Stainless steel round rods are known for their corrosion resistance, strength, and versatility. These rods come in a range of stainless steel alloys (303, 304, and 316) and diameters to suit different applications.

Alloys & Finishes

Alloys

303 Stainless Steel
Type 303 is a versatile machining grade of stainless steel known for its exceptional ease of machining, grinding, and polishing. It is the most free-machining option available. 303 stainless steel offers oxidation resistance at elevated temperatures up to 1700°F and a melting point of 1400°F.

Characteristics of alloy 303:
Machinability = Excellent
Corrosion Resistance = Good
Weldability = Not recommended
Bending/Forming = Fair
Magnetic = No

Common applications of alloy 303:

• Projects requiring extensive machining.
• Supports, beams, and railings.
• Screw machining.
• Fasteners and fittings.
• Parts with intricate shapes.
• Pump and valve parts.
• Bushings and shafts.

304 Stainless Steel
Type 304 is the most commonly used stainless steel alloy. It stands out with its strong formability and excellent weldability. It can be easily roll-formed or bent to suit specific needs making it a top choice for various applications. 304 offers reliable corrosion resistance and performs well in both chemical and atmospheric conditions.

Characteristics of alloy 304:
Machinability = Fair
Corrosion Resistance = Good
Weldability = Excellent
Bending/Forming = Good
Magnetic = No

Common applications of alloy 304:

• Best general-purpose stainless steel and is suitable for a broad range of applications.
• Food processing equipment, including containers and conveyors.
• Kitchen appliances, such as sinks, cookware, countertops, and backsplashes.
• Architectural elements like railings and panels.
• Chemical processing equipment, including tanks and piping.
• Medical instruments and devices.

316 Stainless Steel
Type 316 stainless steel stands out with its superior corrosion resistance and elevated temperature strength, surpassing that of type 304. This high-corrosion resistance alloy is particularly effective against pitting-type corrosion. Our stainless steel sheet is dual-certified as 316/316L, a crucial feature for preventing corrosion after welding. It excels in welding, machining, grinding, and forming applications, making it a versatile choice for various industries. (Sometimes 316 is referenced as “marine grade” because of its excellent corrosion resistance (better than 304).)

Characteristics of alloy 316:
Machinability = Fair
Corrosion Resistance     = Excellent
Weldability = Excellent
Bending/Forming = Good
Magnetic = No

Common applications of alloy 316:

• Best for corrosion resistance and hygiene.
• Marine equipment, including boat hardware and propellers.
• Pharmaceutical processing equipment.
• Chemical industry equipment.
• Food processing equipment.
• Medical equipment, such as surgical instruments and orthopedic implants.

Finishes

What is a Mill Finish?
Mill finish means that items come to exactly as they are finished at the mill. All materials can have some surface scratches and may have a dull finish. If you want a certain type of finish on your material, give us a call at 812-429-1634.
