Stainless Steel Material Overview
Stainless steel is a corrosion-resistant iron-based alloy containing a minimum of 10.5% chromium, forming a self-healing passive chromium-oxide surface film. Enhanced with nickel, molybdenum, titanium, and nitrogen, stainless steel delivers outstanding mechanical strength, high thermal endurance, and aesthetic brilliance across demanding chemical, food processing, marine, and oil & gas applications.
Trident Metal & Alloys manufactures and stocks a complete range of stainless steel sheets, plates, coils, round bars, structural angles, seamless pipes, and forged fittings. All consignments are supplied with EN 10204 3.1 Mill Test Certificates (MTCs), complete heat traceability, and Positive Material Identification (PMI) compliance.
