🔹 About DIN 1.4501 (Super Duplex)

DIN 1.4501, also known as UNS S32760, Alloy 100, or F55, is a super duplex stainless steel with a balanced ferrite–austenite microstructure. It combines high mechanical strength with exceptional resistance to pitting, crevice, and stress corrosion cracking, making it ideal for seawater and sour service environments.

Key Features:

• Twice the strength of standard austenitic stainless steels

• Excellent resistance to chloride-induced corrosion

• PREn value ≥ 40, ensuring superior pitting resistance

• Non-magnetic, excellent toughness, and weldability
