Alloy 304/304H Pipe & Fittings

Stainless Steel 304H Alloy Pipe

Alloy 304H (UNS S30409) Type 304/304H  is a modification of Type 304 with carbon content controlled in the range of 0.04 to 0.10 for increased strength at temperatures above approximately 800 degrees F. Unlike 304L, Type 304/304H with a higher carbon content makes the steel more suitable for use in higher-temperature applications.
