Hashmi Sheets and Plates is a trusted manufacturer and supplier of NACE MR 0103 / MR 0175 HIC Boiler Sheets and Plates, operating from Doha, Qatar. The company focuses on supplying materials built to survive the harshest industrial environments—where pressure, heat, and corrosive media are constant threats. With strict quality control, advanced testing, and deep technical understanding of sour service requirements, Hashmi Sheets and Plates delivers products that perform when failure is not an option. Known for reliability, precision, and timely supply, the company supports critical oil, gas, and power projects with confidence and consistency.
These boiler sheets and plates are produced from carefully controlled low-carbon steel compositions designed to resist hydrogen-induced cracking and sulfide stress cracking. Clean steelmaking practices, low sulfur levels, and controlled microstructure ensure excellent toughness and structural integrity. The material offers high tensile strength, good yield strength, and strong impact resistance, even under high pressure and elevated temperatures. Engineered specifically for sour service conditions, these plates maintain mechanical stability and reliability where standard materials would fail.
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.

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.
NACE MR 0103 / MR 0175 HIC Boiler Sheets and Plates are used in environments where corrosion, hydrogen exposure, and pressure are relentless. They are essential in oil and gas processing units, sour service pipelines, pressure vessels, boilers, heat exchangers, and refinery equipment. These plates are widely trusted in power plants, petrochemical facilities, and offshore installations. Their resistance to cracking and long-term structural degradation makes them ideal for critical systems where safety, durability, and uninterrupted operation are mandatory—not optional.
