904L Stainless Steel Strip
What is 904L Stainless Steel Strip?
904L super austenitic stainless steel is a low carbon, high nickel, and high molybdenum austenitic stainless steel. It possesses excellent activation-passivation capabilities and superior corrosion resistance. This alloy performs exceptionally well in non-oxidizing acids such as sulfuric acid, acetic acid, formic acid, and phosphoric acid. It also offers good resistance to pitting in neutral media containing chloride ions, as well as resistance to crevice corrosion and stress corrosion cracking.
904L stainless steel is suitable for use with all concentrations of sulfuric acid below 70°C. It can also handle acetic acid and mixtures of formic acid and acetic acid at any concentration and temperature under normal pressure, demonstrating outstanding corrosion resistance in these environments.
Features of 904L Stainless Steel Strip
Features of 904L Stainless Steel Strip
Corrosion Resistance:
Stainless steel is renowned for its exceptional corrosion resistance. The chromium in stainless steel reacts with oxygen to form a dense oxide film (chromium oxide layer), which prevents further oxidation and corrosion of the steel surface. This property makes stainless steel highly resistant to the erosion of most chemical media, making it ideal for use in environments containing water, gases, and chemicals.
High Temperature Performance:
Stainless steel retains its excellent performance at high temperatures, maintaining structural stability and strength over extended periods. This capability makes stainless steel suitable for high-temperature processes and applications, such as those in the petrochemical and energy production industries.
Mechanical Properties:
Stainless steel boasts superior mechanical properties, including strength, hardness, and ductility. These qualities make it highly valued in various manufacturing sectors, including the automotive, aerospace, construction, and manufacturing industries.
Aesthetic Appeal:
Stainless steel has a smooth and uniform surface, which can be finished in various ways, such as polishing, brushing, or painting, to achieve different aesthetic effects. This versatility makes stainless steel a popular choice in architectural decoration, furniture manufacturing, art production, and other fields.
Sustainability:
Stainless steel is a recyclable material, contributing to reduced resource consumption and environmental pollution through recycling and reuse. This aligns with sustainable development principles, making stainless steel an environmentally friendly choice.
