Distributors of Specialty Stainless Steel and High Grade Nickel Alloys.



304/304H is an austenitic chromium-nickel alloy known to be among the most adaptable and widely applied stainless steels in the 300 series. The higher carbon content in 304H makes for an amplified tensile and yield strength. This versatile alloy can often be found in pipelines, condensers, heat exchangers, oil refining, power generation industry, and gas and chemical industries.
