is the designated "Service Section" within the ASME Boiler and Pressure Vessel Code (BPVC) that contains the essential specifications for welding rods, electrodes, and filler metals. It serves as a mandatory technical reference for engineers, manufacturers, and inspectors to ensure that welding consumables used in pressure-retaining components meet strict safety and quality standards. Core Purpose and Scope
Specifies the manufacturer's responsibility for testing and what happens if a test specimen fails.
ASME Section II Part C is a core material standard. It provides requirements for filler materials used in pressure vessel construction and fabrication. asme section ii part c pdf
Nickel and nickel-alloy bare welding electrodes and rods.
: The maximum stress a material can withstand before breaking.
is unique because it largely adopts the American Welding Society (AWS) A5 series specifications. In ASME terminology, these are designated as SFA specifications (e.g., SFA-5.1, SFA-5.18). The “SFA” prefix indicates that the standard has been approved by ASME for use in BPVC construction, often with minor modifications specific to pressure equipment. : The official site to purchase the 2025
| SFA Number | Common Name | Typical Application | | :--- | :--- | :--- | | SFA-5.1 | Carbon Steel Covered Electrodes | Pressure vessel shell welding | | SFA-5.4 | Stainless Steel Covered Electrodes | Corrosion-resistant overlay | | SFA-5.11 | Nickel & Alloy Covered Electrodes | Low-temperature or high-alloy service | | SFA-5.18 | Carbon Steel Solid Wires | GMAW (MIG) for boiler tubes | | SFA-5.20 | Carbon Steel Flux-Cored Electrodes | High-deposition welding |
The ASME Section II Part C PDF is organized logically by material types and welding processes. Each "SFA" specification provides a blueprint for a specific category of filler metal. Key SFA Specifications to Know:
The specification defines the precise allowable percentages of chemical elements (such as Carbon, Manganese, Silicon, Chromium, Nickel, and Molybdenum) in the weld metal. Controlling trace elements like Phosphorus and Sulfur is critical to preventing weld defects like hot cracking. Mechanical Property Requirements Nickel and nickel-alloy bare welding electrodes and rods
However, do not assume ASME SFA and AWS are identical. ASME often adds supplementary requirements, especially for nuclear applications (Section III). Always use the ASME version, not the AWS version, for code work.
(Specification for Carbon Steel Electrodes for Shielded Metal Arc Welding) becomes ASME SFA-5.1 in Part C.

Section II is divided into four main parts to organize material data efficiently: Part Key Designations Ferrous Material Specifications (Steel, iron, etc.) Part B Nonferrous Material Specifications (Aluminum, copper, etc.) Part C Welding Rods, Electrodes, and Filler Metals SFA-X.X Part D
ASME Section II Part C cannot be used in isolation. It functions as a bridge between design requirements and practical fabrication:
