The 2101 Duplex Stainless Steel Plate, also referred to as 2101 Duplex Stainless Steel Sheet, is a lean duplex stainless steel designed to provide a balanced combination of corrosion resistance and mechanical strength. Its dual-phase microstructure of ferrite and austenite ensures high strength while maintaining good toughness and formability.
The chemical composition of 2101 Duplex Stainless Steel includes approximately 21% chromium, 1% nickel, and 1.5% manganese, making it highly resistant to general corrosion and moderate chloride stress corrosion environments. Produced according to international standards such as ASTM A240, ASME SA240, and EN 1.4162, our plates come with complete material test certificates (MTC) and can undergo third-party inspection (SGS, BV, TÜV) for quality assurance.
Key Features & Advantages
Cost-Effective – Lower nickel content than traditional duplex grades reduces material cost while maintaining good corrosion resistance.
High Strength – Superior yield strength compared to conventional austenitic stainless steels allows for thinner material design.
Good Corrosion Resistance – Resistant to general corrosion and mild chloride environments.
Reliable Quality – Supplied with full traceability, MTC, and optional third-party certifications.
Versatile Fabrication – Excellent weldability and formability for various engineering applications.
Applications
2101 Duplex Stainless Steel Plate is widely used in industries where moderate corrosion resistance and high strength are required:
Chemical and petrochemical equipment
Piping and pressure vessels
Storage tanks and heat exchangers
Automotive and transport applications
Construction and architectural structures
