Part A - Ferrous Material Specifications This Part is a supplementary book referenced by other sections of the Code. It provides material specifications for ferrous materials which are suitable for use in the construction of pressure vessels. The specifications contained in this Part specify the mechanical properties, heat treatment, heat and product chemical composition and analysis, test specimens, and methodologies of testing. The designation of the specifications start with 'SA' and a number which is taken from the ASTM 'A' specifications. Part B - Nonferrous Material Specifications This Part is a supplementary book referenced by other sections of the Code. It provides material specifications for nonferrous materials which are suitable for use in the construction of pressure vessels. The specifications contained in this Part specify the mechanical properties, heat treatment, heat and product chemical composition and analysis, test specimens, and methodologies of testing. The designation of the specifications start with 'SB' and a number which is taken from the ASTM 'B' specifications. Part C - Specifications for Welding Rods, Electrodes, and Filler Metals This Part is a supplementary book referenced by other sections of the Code. It provides mechanical properties, heat treatment, heat and product chemical composition and analysis, test specimens, and methodologies of testing for welding rods, filler metals and electrodes used in the construction of pressure vessels. The specifications contained in this Part are designated with 'SFA' and a number which is taken from the American Welding Society (AWS) specifications. Part D - Properties (Customary/Metric) This Part is a supplementary book referenced by other sections of the Code. It provides tables for the design stress values, tensile and yield stress values as well as tables for material properties (Modulus of Elasticity, Coefficient of heat transfer et al.) ASME BPVC Section III - Rules for Construction of Nuclear Facility Components Section III of the ASME Code Address the rules for construction of nuclear facility components and supports. The components and supports covered by section III are intended to be installed in a nuclear power system that serves the purpose of producing and controlling the output of thermal energy from nuclear fuel and those associated systems essential to safety of nuclear power system. Section III provides requirements for new construction of nuclear power system considering mechanical and thermal stresses
