Gudaha ASTM A213, marka lagu daro shuruudaha guryaha xajinta iyo adkaanta, tijaabooyinka soo socda ayaa sidoo kale loo baahan yahay: Tijaabada Fiican iyo Tijaabada Laab.
ASTM A335 P22(ASME SA335 P22) waa adeeg heerkul sarreeya oo birta birta ah ee chromium-molybdenum, oo si ballaaran loo isticmaalokululeeyahaKuleyliyaha sare, iyo kulaylkasariflayaasha.
Waxay ka kooban tahay 1.90%ilaa 2.60% chromium iyo 0.87% ilaa 1.13% molybdenum, waxay leedahay iska caabin kulayl aad u fiican, waxayna sidoo kale ku habboon tahay foorarsiga, qallafsanaanta, ama hawlgallada la midka ah.
UNS nambarka: K21590.
ASTM A335 waa qeexitaanka caadiga ah ee tuubooyinka birta-birta-garab-ka-soo-baxa ee aan-ka-soo-kabashada lahayn ee loogu talagalay adeegga heerkulka sare. Waxaa si weyn loogu isticmaalaa kuleyliyaha, kuleyliyaha sare, kuleyliyeyaasha, iyo codsiyada kale ee ku shaqeeya heerkulka sare iyo xaaladaha cadaadiska sare. Marka lagu daro Fasalka P22, darajooyinka kale ee daawaynta caadiga ah waxaa ka mid ahP5 (UNS K41545), P9 (UNS K90941), P11 (UNS K11597)iyoP91 (UNS P90901).
Soo saaraha iyo Xaaladda
ASTM A335 P22 tuubooyinka birta waa in lagu sameeyaa habka aan kala go 'lahayn waana inay noqdaan kuwo kuleyl ah ama qabow lagu sawiray daawaynta.
Tuubooyinka birta ah ee aan cillad lahaynwaa tuubooyinka aan alxanka lahayn, kuwaas oo bixiya tuubooyinka birta ee P22 oo leh xasilooni sare iyo isku hallayn heerkul sare iyo jawi cadaadis sare leh.
Daawaynta kulaylka
Tuubooyinka birta ah ee P22 waa in dib loo kululeeyaa oo lagu daaweeyaa kuleyl iyadoo la isticmaalayo nuugista buuxda, soo-jiidashada soothermal, ama caadiyaynta iyo dabci.

Chromium (Cr) iyo molybdenum (Mo) waa walxo alloying furaha ah ee birta P22, hagaajinta xoogga heerkulka sare, caabbinta oksaydhka, iyo cimri dhererka. Halabuurka kiimikada gaarka ah ayaa lagu muujiyay hoos:

| P22 | 0.05 ~ 0.15 | 0.30 ~ 0.60 | 0.025 max | 0.025 max | 0.50 max | 1.90 ~ 2.60 | 0.87 ~ 1.13 |
Tijaabooyinka hantida makaanikada ee P22 waa in lagu fuliyaa si waafaqsan shuruudaha la xiriira ASTM A999.
