Product Details
904L Stainless Steel Bar Description
Grade 904L is a super-austenitic, low-carbon, high-alloy stainless steel. The addition of copper to this grade greatly increases its resistance to strong reducing acids, especially sulfuric acid. It is also highly resistant to chloride attack, including pitting/crevice corrosion and stress corrosion cracking.

Application areas
Steel is widely used in steel‑structure industrial buildings, bridge frameworks, the main structural systems of high‑rise buildings, and infrastructure projects such as highways and oil‑and‑gas pipelines. Its high strength ensures structural load‑bearing stability and seismic performance. In shipbuilding, steel is employed to fabricate hull structures, decks, and internal components. Hot‑rolled coil, with its excellent load‑carrying capacity, can withstand harsh operating conditions.
