Tshuaj muaj pes tsawg leeg ntawm S31254 yeeb nkab
Cov tshuaj muaj pes tsawg leeg ntawm S31254 yog qhov tseem ceeb ntawm nws qhov kev ua tau zoo. Nws muaj pes tsawg leeg yog: chromium (Cr) 19.5% -20.5%, npib tsib xee (Ni) 17.5% -18.5%, molybdenum (Mo) 6.0% -6.5%, nitrogen (N) 0.18% -0.22%, thiab nruj me ntsis tswj cov pa roj carbon (C Tsawg dua los yog sib npaug rau 0.02% sulfur thiab 0.02%).

Kev tsim khoom: 254SMO Seamless vs. Welded Pipes
Txhawm rau ua kom tau raws li ntau hom kev lag luam piping specifications, peb muab cov khoom no rau hauv ob hom kev tsim khoom sib txawv:
254SMO Seamless Yeeb Nkab (ASTM A312 / ASTM B622)
Tsim los ntawm kub- dov tho los yog extrusion ua raws li kev kos duab txias thiab txias dov. Cov txheej txheem no ua rau muaj qhov ua tau zoo ntawm qhov ntev, qhov tsis zoo ntawm qhov chaw tiav, thiab kev ua haujlwm siab tshaj -.
S31254 Welded yeeb nkab (ASTM A312 / ASTM B619)
Ua los ntawm siab - zoo steel strips los yog daim hlau ntawm automated longitudinal vuam. Peb siv cov txheej txheem siab tshaj plaws argon arc vuam (TIG) ua ke nrog cov khoom siv hluav taws xob tsawg thiab tshwj xeeb tshaj li - alloyed npib tsib xee-raws li cov khoom siv hlau (xws li ERNiCrMo-3). Txoj kev no tshem tawm thermal cracking thiab txwv intergranular alloy segregation nyob rau hauv weld seam.
Critical Heat Treatment & Solution Annealing
Tag nrho peb cov 254SMO piping undergoes nruj tshuaj annealing ntawm 1149℃(2100℃F) ua raws li los ntawm ib tug ceev dej quench. Qhov tseem ceeb thermal ua no dissolves teeb meem intermetallic theem, homogenizes tseem ceeb alloying ntsiab, thiab tag nrho restores siab tshaj corrosion kuj ua ntej shipping.
Kev Tswj Xyuas Zoo, Cov Qauv Ntsuas, thiab Qhov Loj
Txhua qhov kev tsim khoom ib zaug dhau los ua qhov kev ntsuam xyuas zoo los lav tag nrho kev ua raws li cov qauv kev yuav khoom thoob ntiaj teb:
Dimensional Integrity:Muaj tag nrho thoob plaws cov txheej txheem, suav nrog Schedule 10S, Sch 40S, thiab Sch 80S.
Tsis yog -Kev Ntsuas Kev Puas Tsuaj (NDT):100% Hydrostatic kuaj thiab Eddy Tam sim no lossis Ultrasonic tshuaj xyuas.
Kev kuaj Corrosion:Kev soj ntsuam nruj ntawm ASTM G48 Txoj Kev A pitting thiab crevice corrosion kuaj kom paub meej tias muaj kev ntseeg siab.
Cov ntaub ntawv:Ua tiav Mill Test Certificate (MTC) muab tag nrho raws li EN 10204 3.1 lossis 3.2.
