These base metals are grouped by material and assigned P Numbers based on what material they are. For example, the P Number 1 is assigned to Carbon Manganese or Low Carbon Steel base metals.
What is P NO and F no?
The ASME grouping is made using the alphanumeric designation P-No for the base metal and F-numbers (F-No) for the filler material. This grouping is based on comparable characteristics of the material such as weldability, mechanical properties and composition.
What is P number and s number?
THE “S NUMBER”: 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.
E8010-P1 is an excellent all-position, cellulosic mild steel electrode providing strong, dependable, X-ray quality welds. It delivers great arc stability and the best penetration possible when welding pipe steels with silicon contents of up to 0.30.
What does P1 mean in welding?
The P1 designation is assigned by the American Society of Mechanical Engineers (ASME) to materials that meet certain criteria for chemical and mechanical properties. These materials are specified in ASME section IX, which is the standard for welding qualification. P1 materials are simple carbon steel materials.
