Mild Steel Material Overview
Mild steel (low-carbon steel containing 0.05% to 0.25% carbon) is a versatile, highly ductile, and economically efficient alloy utilized extensively for water transmission, civil infrastructure, structural framing, HVAC loops, and general plant utility lines. Its excellent field weldability, high impact resistance, and ease of hot/cold fabrication make it a dependable standard for industrial fluid conveyance.
Trident Metal & Alloys manufactures and stocks a comprehensive inventory of MS ERW pipes, MS pipe fittings, and heavy-duty MS seamless tubing. All consignments are accompanied by EN 10204 3.1 Mill Test Certificates (MTCs), hydrostatic pressure reports, and optional hot-dip galvanizing for enhanced atmospheric corrosion protection.
