What is SA 516 GR.70N NACE and MR 0103-0175 Plates?

The SA 516 GR.70N NACE and MR 0103-0175 Plates are primarily made up of carbon, manganese, silicon, phosphorus, and sulfur, all crafted to ensure outstanding notch toughness and corrosion resistance in sour service environments. These plates boast a minimum tensile strength ranging from 485 to 620 MPa and a yield strength of about 260 MPa, with improved impact properties thanks to normalization. Their unique chemical makeup and mechanical balance make them ideal for pressure vessels and boilers that face hydrogen sulfide-rich conditions, ensuring they remain durable, weldable, and perform reliably over the long haul, even in harsh environments.

SA 516 GR.70N NACE and MR 0103-0175 Plates Specifications

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.
