The introduction of chrome molybdenum increases the materials temperature tensile strength making ASTM A387-2-2 an excellent choice for elevated temperature environments. The material also displays excellent corrosion resistant characteristics. ASTM A387-2-2 is therefore ideal for the fabrication of weldable steel pressure vessels and industrial boilers found commonly in the petrochemical and oil industry.
