ASME SA203 GR.E Boiler and Pressure Vessel Steel Plate

ASME SA203 Grade E is a specification for pressure vessel steel plate, which is used for high-temperature service applications. The "SA" in SA203 stands for "Specification for ASME (American Society of Mechanical Engineers) A/SA-203."

The steel plate is composed of alloy materials, including nickel, chromium, and molybdenum, which provide excellent resistance to high-temperature environments. The plate is also designed to withstand high-pressure applications, making it suitable for use in pressure vessels and boilers.

The mechanical properties of ASME SA203 Grade E steel plate are as follows:

• Tensile strength: 80-100 ksi (550-690 MPa)
• Yield strength: 57 ksi (390 MPa)
• Elongation in 2 inch (50 mm): 17%
