American Society of Mechanical Engineers (ASME) Codes. The American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC) covers all aspects of design and manufacture of boilers and pressure vessels. All sections contain welding specifications, however most relevant information is contained in the following. ASME SFA A5.18 75% Argon / 25% CO 2 98% Argon / 2% CO 2 100% CO 2 77,000 psi. Part Number Description Wire Diameter Weight MSS E70S612MS ER70S-6.023 - 2 lb. Casino filipino malate manila website. Part C specifications are designated by SFA numbers and are derived from AWS specifications. BPVC Section III – Rules for Construction of Nuclear Facility Components Provides general requirements which address the material, design, fabrication, examination, testing and overpressure protection of the items specified within each respective.
ASME P Number
To reduce the number of welding and brazing procedure qualifications required base metals have been assigned P-Numbers by the ASME BPVC. Ferrous metals which have specified impact test requirements have been assigned Group Numbers within P-Numbers.
These assignments have been based on comparable base metal characteristics, such as:
- Composition
- Weldability
- Brazeability
- Mechanical Properties
The S-Number was removed from ASME Section IX in 2009. The S Number’s purpose was identical to the P Number. However, these numbers were assigned to those materials included for pipework to the ASME B31 Code for Pressure Piping. These materials were also covered by the P-Number, but not the converse. And calculated ferrite number (FN) available online. 0.03% carbon content increases resistance to intergranular corrosion.

AWS ER316, ER316L KEY FEATURES AWS A5.9/A5.9M: ASME SFA-A5.9: EN ISO 14343-B: ER316, ER316L ER316.
Indiscriminant substitution of materials in a set of P-Numbers or Group Numbers may lead to problems or potentially failures. Engineering assessment is necessary prior to a change in materials.
When a base metal with a UNS number Designation is assigned a P-Number, then a base metal listed in a different ASME material specification with the same UNS number shall be considered that P-Number.
The table below is a guide and is for instructive purposes only. Anyone specifying materials or requirements should refer directly to the ASME Boiler and Pressure Vessel Code to specify materials.

ASME F Number
The F-number grouping of electrode and welding rod in QW-432 is based essentially on their usability characteristics, which fundamentally determine the ability of welders to make satisfactory welds with a given filler metal. This grouping is made to reduce the number of welding procedure and performance qualifications, where this can logically be done. The grouping does not imply that base metals or filler metals within a group may be indiscriminately substituted for a metal which was used in the qualification test without consideration of the compatibility of the base and filler metal from the standpoint of metallurgical properties, PWHT design and service requirements, and mechanical properties.
F Number | General Description |
1 | Heavy rutile coated iron powder electrodes :- A5.1 : E7024 |
2 | Most Rutile consumables such as :- A5.1 : E6013 |
3 | Cellulosic electrodes such as :- A5.1 : E6011 |
4 | Basic coated electrodes such as : A5.1 : E7016 and E7018 |
5 | High alloy austenitic stainless steel and duplex :- A5.4 : E316L-16 |
6 | Any steel solid or cored wire (with flux or metal) |
2X | Aluminium and its alloys |
