What is 304 cold drawn stainless steel flat bar ?
The 304 cold drawn stainless steel flat bar is formed through cold drawing, achieving a thickness tolerance of ±0.1 mm and a width tolerance of ±0.5 mm, with a surface roughness of Ra ≤ 1.6 μm. It requires no secondary processing and is suitable for precision mechanical assemblies such as flange gaskets and equipment supports, saving up to 40% in machining time.

Advantages of 304 Stainless Steel Flat Bar
🔹The 304 cold drawn stainless steel flat bar, composed of 18% chromium and 8% nickel (Cr18Ni8), offers an excellent balance of corrosion resistance and workability. It performs well in atmospheric, freshwater, and mildly acidic or alkaline environments, passing salt spray tests for over 500 hours without red rust. Compared to carbon steel, it delivers significantly better overall performance, while costing only about 60% of 316 stainless steel.
🔹After cold drawing, the 304 stainless flat bar achieves a 20% increase in strength, with tensile strength ≥600 MPa and hardness in the range of HRB 90–95. It also exhibits excellent bend resistance, with no cracking during 180° bending (for thicknesses ≤10 mm).
