Unique Features:

1.4539 904L Stainless Steel Sheet is specifically designed for harsh environments, offering superior resistance to a wide range of acids, including sulfuric acid, phosphoric acid, and hydrochloric acid. The addition of copper (up to 1-2%) enhances its resistance to sulfuric acid, while the high nickel content (up to 25%) improves its overall corrosion resistance. This makes 904L particularly effective in chemical and marine environments. The material is also highly resistant to stress corrosion cracking, ensuring reliability and longevity in even the most demanding industrial settings. Furthermore, its excellent weldability and formability make it easy to fabricate into various shapes and sizes.
