Overview|Specifications|Applications|Finish Options|How to Measure|Order Checklist

Type 304 stainless steel, often called "18-8," is the most widely used austenitic chromium-nickel alloy. In its annealed condition, it is non-magnetic, highly formable, and maintains its properties at low temperatures. This flat bar, produced to ASTM A276 standards, combines this material's exceptional resistance to atmospheric and chemical corrosives with a versatile, rectangular profile for fabrication projects.

As a medium-sized bar, this 1-1/4" wide profile is ideal for creating structural bracing, machine ways, equipment framework, and wear strips. Its balance of size and strength makes it a reliable component for both functional and architectural applications where durability is key.
