SA 516 55 is a carbon steel plate under ASME SA 516, designed for pressure vessels with a tensile strength of 380-515 MPa, ideal for low-pressure applications.Gangsteel manufactures and exports ASME SA 516 GR 55, ensuring high weldability and toughness. This article details its properties, applications, and advantages.
SA 516 Grade 55, or ASME SA 516 GR 55, is the lowest strength grade in the SA 516 family, designed for pressure vessels and boilers operating at moderate and low temperatures. Its lower tensile strength makes it suitable for less demanding applications, offering excellent ductility and cost-effectiveness.
