ASME SA 387 GRADE 12 Class 1 steel

ASME SA 387 Grade 12 Class 1 is a specification for low-alloy chromium-molybdenum steel plates used in the fabrication of pressure vessels and boilers. The "SA" in SA 387 stands for "Specification for ASME (American Society of Mechanical Engineers) A/SA-387."This steel grade contains chromium and molybdenum, which increases its strength and corrosion resistance. Class 1 refers to the type of heat treatment used during manufacturing, which involves normalization and tempering.

ASME SA 387 Grade 12 Class 1 steel is primarily used in high-temperature and high-pressure service applications, such as in the petrochemical and power generation industries. It is also used in the fabrication of boilers, pressure vessels, and heat exchangers.The specification sets standards for chemical composition, mechanical properties, and other important parameters to ensure that the steel plates produced according to this specification are of high quality and meet the required standards. The use of this specification provides assurance that the plates will be able to perform under extreme conditions, providing a high degree of reliability and safety.
