Which ASME section specifically addresses materials used in construction?

Section II of the ASME Boiler and Pressure Vessel Code is specifically dedicated to materials used in construction, and it is divided into different Parts which provide comprehensive guidelines related to various types of materials. Part A covers ferrous materials, Part B focuses on nonferrous materials, Part C deals with specifications for high-strength bolting materials, and Part D addresses properties of materials. This structured approach allows fabricators and inspectors to reference the correct materials standards for different construction processes.

In contrast, other sections address different aspects of boiler and pressure vessel design and operational criteria. Section I deals with power boilers, including rules for construction and design. Section III pertains to nuclear component design, outlining requirements for materials and design specific to nuclear applications. Section V focuses on nondestructive examination techniques, which do not primarily concern material specifications but rather the assessment of material integrity. Hence, Section II is the authoritative source for material specifications in the ASME code.
