304 lamiera di acciaio inossidabile

Panoramica

Alloy 304/304H (UNS S30400/S30409) is a modified version of the widely used “18-8” chromium-nickel austenitic stainless steel. It features a controlled carbon content of 0.04-0.10%, which increases its strength at temperatures above 800°F (427°C). This alloy is both economical and versatile, making it suitable for various general-purpose applications.

Corrosion Resistance

Alloy 304/304H offers general corrosion resistance similar to 304/304L. It resists atmospheric corrosion and performs well in moderately oxidizing and reducing environments. However, its high carbon content makes it prone to carbide precipitation in the heat-affected zones of welds.

Magnetic Properties and Fabrication

In the annealed condition, Alloy 304/304H is non-magnetic but may become slightly magnetic after cold working or welding. It can be easily welded and processed using standard shop fabrication practices.
