Navgraha Steels INC is a trusted stockist and exporter of SA 516 Gr 60/70 Dual Certified Plates, Sheets & Coils, sourced from leading mills like Sail, AMNS, JSPL, Evonith, Nippon Yakin, Outokumpu, Special Metals, VDM, and ATI. Dual certification offers buyers the flexibility to meet specifications of both Grade 60 and Grade 70 in a single material, reducing procurement risk and ensuring compliance with multiple project requirements.
In critical boiler and pressure vessel projects, one wrong certificate can lead to shutdown delays, audit failures, and millions in losses.
In boiler and pressure vessel projects, even a small error in certification can lead to shutdowns, audit delays, and expensive re-sourcing.
In large boiler and refinery projects, one wrong certification can mean audit rejection, costly delays, and re-sourcing headaches.
Dual certification means that the steel plates, sheets, or coils meet the chemical and mechanical requirements of both SA 516 Gr 60 and Gr 70.
Procurement Benefit: Simplifies sourcing for EPC contractors handling multi-standard projects.
