304 Stainless Steel Roll Forming Material Guide: Coil Sizes, Properties & Applications

Stainless Steel 304 Roll Forming Material

1. Overview of 304 Stainless Steel in Roll Forming

304 stainless steel is the most widely used stainless steel grade in the world. It is an austenitic stainless steel known for its excellent corrosion resistance, good formability, and versatility.

In roll forming, 304 is the go-to material for applications requiring hygiene, durability, and long-term corrosion resistance. It is heavily used in food processing, construction, architectural panels, and industrial systems.

Compared to 201, 304 offers significantly better corrosion resistance, making it suitable for outdoor and mildly aggressive environments.

2. Material Composition & Structure

304 stainless steel consists of:

Iron base metal
Chromium (~18–20%)
Nickel (~8–10.5%)

Structure

Austenitic stainless steel
Non-magnetic (annealed condition)
May become slightly magnetic after forming
