Nestled in the industrial heart of Manila, Diaz Sheetsandplates stands as your dedicated partner for high-performance steel. We specialize in manufacturing and supplying NACE MR 0103-0175 HIC Boiler Sheet and Plates, providing engineered solutions for critical environments. Our commitment is to deliver not just a product, but a promise of reliability and longevity for your most demanding projects, backed by our deep-rooted expertise in the local landscape.
The composition of our NACE HIC-resistant Boiler Sheet and Plates is specifically designed to combat corrosion. These steels possess precise chemical controls, particularly in sulfur and phosphorous content, which grant them exceptional resistance to hydrogen-induced cracking. This results in robust mechanical properties, including excellent tensile strength and impact toughness, ensuring structural integrity even in the most challenging service conditions where safety is non-negotiable.
Grade : ASME SA 516 GR.70N Boiler and Pressure Vessel Steel Plates
Width : 1000mm-4500mm
Thickness : 5mm-150mm
Length : 3000mm-18000mm
Supply Condition : As Rolled, Normalized Rolling, Furnace Normalizing, Vacuum Degassing, Simulated Post-Weld Heat Treatment or as per customer requirement.
Impact tested : 52° C
Tempering : Notch toughness can be improved by quenched cooling from hot rolling or normalizing by the supplier. If such a faster cooling rate is agreed upon between purchaser and supplier then the steel is also to be tempered at 1200 F.
Applications : Used for weld fabrication of pressure vessels that require improved notch toughness for lower than ambient temperature service.
Process of Manufacturing : Hot-Rolled (HR)

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
NACE MR 0103/0175 HIC Boiler Sheets and Plates offer exceptional resistance to hydrogen-induced cracking (HIC), making them ideal for high-sulfur environments. They provide superior corrosion resistance, especially in acidic and sulfide-rich conditions, ensuring long-term durability and reliability. These materials also exhibit excellent mechanical properties, such as high tensile strength and toughness, making them suitable for demanding applications in oil and gas, chemical processing, and power generation industries. Their resistance to stress corrosion cracking ensures enhanced performance and longevity in harsh environments.
These specialized plates are the go-to choice for constructing pressure vessels, boilers, and piping systems within the oil and gas industries, especially in sour service. They are equally vital in petrochemical plants and refineries, where exposure to corrosive elements is a constant. By choosing this material, you are building a legacy of safety and reliability, ensuring your infrastructure remains secure against the threats of cracking and corrosion for years to come.
