boiler-plateThe Boiler Steel Plates are widely used in fabrication of boilers in industries. These hot rolled steel plates are made available in variety of grades and thickness and are developed to a superior quality, deliberated to hold out the internal pressure in boilers and valves.

Well known for its diversity of use and longevity, these boiler plates meet the exact requirements of the industries. The content of carbon in these high temperature steel plates are between 0.16 %-0.29 %. We also supply hydrogen induced crack resistant steel in SA / A516 Grade 70 HIC.
