ASTM A335 P1 Seamless Alloy Steel Yeeb Nkab: C-Mo Workhorse rau Siab-Tub Piping
A335-P1 steel yeeb nkab yog siab-kub alloy steel yeeb nkab feem ntau siv rau hauv siab- kub thiab siab siab siv xws li boilers, petrochemicals, fais fab thiab lwm yam kev lag luam.
Gnee Steel (Tianjin) Co., Ltd. yog ib qho ntawm feem txhim khu kev qha manufacturers thiab lwm tus neeg ntawm ASTM A335 P1 Seamless Alloy Steel Yeeb Nkab: C-Mo Workhorse rau siab-Tub kub Piping nyob rau hauv Suav teb, kuj txhawb customized kev pab cuam nrog luv nqi. Txais tos rau cov lag luam wholesale luv nqi ASTM A335 P1 Seamless Alloy Steel Yeeb Nkab: C-Mo Workhorse rau Siab-Tub Kub Piping rau muag ntawm no los ntawm peb lub hoobkas. Tiv tauj peb rau cov qauv dawb.
ASTM A335 P1yog seamless ferritic alloy- steel yeeb nkab hauvcarbon-molybdenum (C-Mo)tsev neeg, ua rau siab -kev pabcuam kub. Koj yuav pom nws hauv cov chaw tsim hluav taws xob, cov boilers muaj, thiab cov txheej txheem refinery kab uas cov pa roj carbon zoo li ASTM A106 Gr B pib poob lub zog. Qhov sib ntxiv ntawm kwv yees li ib nrab ib feem pua molybdenum yuav tiag tiag creep kuj nyob rau hauv 425-540℃(800-1000℃F) ntau.
Dab tsi Ua A335 P1 txawv ntawm Plain Carbon Steel Pipe
P1 yog qhov tseem ceeb acarbon hlau alloyed nrog 0.44-0.65% molybdenum. Molybdenum yog qhov tseem ceeb. Thaum qhov kub siab siab nws ua rau qeeb qeeb - qhov qeeb, qhov deformation mus tas li ntawm cov yeeb nkab ua rau muaj kev ntxhov siab thiab kub. Qhov ntawd yog raws nraim qhov kev thauj khoom ntawm cov kab hluav taws xob loj lossis lub tshuab hluav taws xob pom. A335 P1 kuj zam me ntsis oxidation ntawm qhov kub thiab txias, uas yog vim li cas nws thiaj li ua rau cov pa roj carbon zoo tshaj plaws hauv kev pabcuam kub kub.
Ib tug ncaj ncees caveat rau buyers: P1 yogtsis yogcorrosion- qib resistant. Nws yuav tsis tawm cov kua qaub, alkalis, lossis ntsev - uas yog txoj haujlwm ntawm stainless lossis siab dua -chromium alloys (A335 P5, P9, P22). Yog vim li cas xaiv P1 yogsiab -kub muaj zog ib duas, tsis muaj corrosion kuj.
