- 304 Stainless Steel Construction
- ASTM A276 Certified
- 73,200 PSI Tensile Strength
- Excellent Corrosion Resistance
Type 304 stainless steel is the most widely used austenitic chromium-nickel alloy, valued for its excellent resistance to a wide range of atmospheric and chemical corrosives. In its annealed condition, it is non-magnetic, highly ductile, and conforms to ASTM A276. This combination makes it a reliable choice for fabrication projects requiring both strength and longevity in various environments.
As a large flat bar with a 3-1/2" width, this product is ideal for heavy-duty applications. Common uses include fabricating robust base plates for machinery, creating strong structural supports and braces, manufacturing die components, and serving as durable wear strips in industrial settings.
