Stainless Steel (Austenitic & Ferritic)
Stainless steel is highly renowned for its excellent corrosion resistance, high temperature strength, and aesthetic appeal. Austenitic grades (300 series) provide exceptional toughness and formability, making them the industry standard for chemical and food processing.

Duplex & Super Duplex Steel
Duplex stainless steels possess a mixed microstructure of austenite and ferrite (50/50), resulting in significantly higher strength than standard austenitic steels and superb resistance to localized corrosion, particularly chloride stress corrosion cracking.
