P-11 is a piping material usually used in refinery and petrochemicals industries for services at or around 550 to 600 degree C temp. It is low alloy steel. It contains 1.25 cr and 0.5moly.It resitant to hydrogen attack. It need PWHT(post weld heat treatment).
PWHT to be in the range of 680 to 780 degree C.

WC9 is cast P22.
it is a high pressure value yes it is a high pressure valve but particularly it is cast P11
LOW CARBON steel material
There are two.
the material looses its shape
I need a p11
Nope- not possible. The P22 is a blowback operated action, and is suitable only for a low powered rimfire cartridge. A .45 requires some form of a locked breech, which the P22 does not have.
Material P22, as per ASTM standards, refers to a specific grade of low alloy steel used primarily for high-temperature applications, particularly in power generation and petrochemical industries. It is designated under ASTM A335, which outlines seamless ferritic alloy steel pipes for high-temperature service. The composition typically includes chromium and molybdenum, providing enhanced strength and oxidation resistance. P22 is often utilized in the construction of pressure vessels, boilers, and piping systems where elevated temperatures and pressures are encountered.
