Steel plate SA 515 GR. 60 GR.70 Boiler Pressure Vessel Sheet
SA516 Gr.60 is a carbon steel plate designated for low and medium-temperature pressure vessels, known for its good strength and toughness.
SA 515 GR. 60 Plates is a grade of carbon steel plate used primarily in pressure vessels and boilers. These plates are designed to operate under moderate or lower temperatures, making them popular in industries such as oil, gas, and petrochemicals.
SA516 steel is divided into several strength grades, including Gr.55, Gr.60, Gr.65, and Gr.70, with increasing tensile and yield strength, It is worth noting that some sources mention SA516 Gr.70 is more commonly specified than Gr.60 in some regions (like China) due to its higher strength.

Some common grades of ASME pressure vessel steel plates include SA516 Gr55, SA516 Gr60, SA516 Gr65, SA516 Gr70, A515 Gr55, A515 Gr60, A515 Gr65, A515 Gr70, SA537CL1, SA537CL2, SA537CL3, A204, SA387 Gr11, SA387 Gr22, A285, and SA387 Gr91, among others.
SA-516-70 is commonly used for pressure vessels where moderate and lower temperature service is required. SA515 GR 70 is used for intermediate and higher temperature service applications. But Both materials adhere to specific ASME standards for pressure vessel applications.
ASME SA516 Grade 60 is a specification of carbon steel plates primarily used in welded pressure vessels and boilers. It is part of the American Society of Mechanical Engineers (ASME) standards, specifically under the ASME Boiler and Pressure Vessel Code
