U. S. Metals diverse inventory offers a full range of Alloy 20 Pipe, Valves, Fittings & Flanges that is prominent in the process
industry. Our support of the power & process industry is reflected in the specialty grades of material that we inventory to support outage & maintenance requirements.
Alloy 20 was originally developed for use in sulfuric acid service found in facilities such as pulp and paper mills. With good general corrosion properties, Alloy 20 usage has expanded in chemical, petrochemical and power generation plants.
Alloy 20 provides excellent resistance to chloride stress corrosion cracking. Post weld heat treatment may not be required for use in some corrosive environments due to resistance to intergranular corrosion in the as-welded condition.
Our ability to provide Alloy® 20 products on a project basis is one of our strongest capabilities and is unmatched in our industry.
Turnarounds or outages, planned retrofits or emergency situations, grassroots projects worldwide; U.S. Metals has the experienced staff to assist you on all of your specialty alloy requirements, no matter how detailed the specification, no matter how
difficult the situation. New industry requirements, not an issue. We work closely with agencies like EPRI along with our utility and refining clients to be on the cutting edge of new industry requirements that affect your high energy/high temperature piping systems.
Our inventory is evolving to meet the new specifications that prevent current issues as creep cracking and hardness problems.
