ASME A335 / ASTM A335 P11 Seamless Alloy Steel Yeeb Nkab
UNS K11597- ASME SA-335 / ASTM A335 P11 yog seamless 1.25% Chromium - 0.5% Molybdenum (1.25Cr-}0.5Mo) ferritic alloy steel yeeb nkab, engineered rau kev pab tas mus li hauv boilers, superheaters, siab hlab ntsha 1pi, thiab siab -335 Paub nyob rau hauv kev lag luam raws li chrome-moly los yog Cr-Mo yeeb nkab, P11 muab txhim khu kev qha creep thiab oxidation tsis kam siab tshaj 400 degree, ua rau nws cov txheej txheem cov khoom siv nyob rau hauv lub hwj chim tiam, petrochemical nroj tsuag, roj refineries, thiab muaj cua sov tshuab thoob ntiaj teb.
Tshuaj muaj pes tsawg leeg (ASTM A335 Table 1)
| Element | C | Mn | Si | Cr | Mo | P (max) | S (max) |
|---|---|---|---|---|---|---|---|
| P11 | 0.05–0.15 | 0.30–0.60 | 0.50–1.00 | 1.00–1.50 | 0.44–0.65 | 0.025 | 0.025 |
Chromium nyob rau hauv 1-1.5% ntau yam tsim ib txheej chromium oxide ruaj khov uas thaiv cov yeeb nkab tiv thaiv siab - kub oxidation thiab scaling. Molybdenum ntawm 0.44-0.65% ntxiv dag zog rau ferrite matrix thiab slows dislocation creep nyob rau hauv sustained load ntawm siab kub. Ua ke, ob lub ntsiab lus alloying no muab P11 nws cov yam ntxwv ua ke ntawm kev ua kom sov thiab ntev - lub sij hawm txhua yam ruaj khov.
