Online Metals 304 Stainless Rectangular Bar
304 stainless steel rectangular bar offers a balance of high strength and corrosion resistance, with a mill finish and annealed condition. The bar measures 3/16″ thick by 1″ wide and 24″ long, making it suitable for food processing, architectural trim, aerospace, and general corrosion-resistant structural components. 304 stainless is a common choice for applications where appearance, cleanability, and resistance to oxidation are important while still delivering solid mechanical performance.
Buying Guide: Key Considerations For High Strength Steel Bars
- Material grade and properties: A36 is a versatile structural steel with good weldability and machinability, while 1095 offers higher hardness and edge retention for knife-making. Stainless grades like 304 provide corrosion resistance in addition to strength.
- Profile and dimensions: Choose round, flat, square, or rectangular bars based on fabrication plans. Consider cross-section stability, bending behavior, and the intended mounting or joining method.
- Heat treatment and finish: Hot-rolled products generally provide toughness and ease of fabrication, while annealed or polished finishes affect machinability and corrosion resistance. Coatings can alter surface properties and reflectivity.
- Weldability and formability: Some grades weld well with common methods; others may require preheating or special filler metals. Plan for cutting, drilling, or stamping tolerances during fabrication.
- Application environment: Corrosion resistance is critical in outdoor or moist environments. Stainless steels protect against rust, while carbon steels require coatings or treatments for longevity.
- Availability and sourcing: Check stock length options, compatibility with your tooling, and lead times. Buying in sets or multiple pieces can reduce costs for larger projects.
- Cost vs. performance: Weigh strength, ductility, and machinability against price. For structural builds, A36 often offers great value; for knives or high-stress applications, consider 1095 or stainless alternatives.
- Safety and compliance: Follow local codes and standard practices for metalworking, welding, and fabrication. Use appropriate PPE and ventilation when cutting or heat-treating.
