UNS N08904 Bolts – Product Overview

Stainless Steel 904L Bolts are manufactured from a low-carbon, high-alloy austenitic stainless steel containing elevated levels of nickel, chromium, molybdenum, and copper. This carefully balanced composition provides outstanding resistance to corrosion in both oxidizing and reducing environments.

Unlike standard austenitic grades, UNS N08904 Bolts offer significantly improved resistance to chloride-induced pitting and crevice corrosion. Their excellent resistance to sulfuric acid makes them particularly valuable in chemical processing applications where equipment reliability and service life are critical considerations.

The low carbon content of 904L Stainless Steel Bolts also improves weldability while minimizing carbide precipitation during fabrication. As a result, these bolts are widely used in industries where corrosion resistance, fabrication flexibility, and mechanical reliability are equally important.

Common applications include chemical processing plants, desalination facilities, offshore platforms, pharmaceutical production units, pulp and paper equipment, flue gas desulfurization systems, and marine installations exposed to harsh operating conditions.
