P235GH belongs rau lub hom ntawm European txheem steel EN10028, uas yog carbon steel thawv steel phaj. Feem ntau, hluav taws xob arc rauv thiab cov pa hluav taws xob saum toj kawg nkaus hloov pauv yog siv rau smelting, thiab cov uas xav tau siab siv tawm ntawm qhov cub refining, electroslag remelting los yog nqus tsev kho mob, lub tshuab nqus tsev induction rauv smelting los yog ob chav nqus smelting, thiab tsim nyog kho cua sov. Cov ntsiab lus ntawm alloying ntsiab yog heev siab. Nws muaj qhov zoo ntawm plasticity, toughness, txias dabtsi yog khoov kev ua tau zoo, thiab vuam kev ua tau zoo thiab tsim nyog rau kev tsim cov hlab ntsha nuclear, cov hlab ntsha siab, thiab cov khoom siv. Piv nrog rau cov hlau zoo tib yam, nws muaj zog dua thiab toughness, txias dabtsi yog khoov thiab vuam kev ua tau zoo, lub cev kev ua tau zoo, tshuaj lom neeg kev ua tau zoo, biocompatibility, thiab cov txheej txheem kev ua tau zoo.
Chemical Composition (%) ntawm P235GH Pressure Vessel Steel
P235GH cov tshuaj pleev ib ce tau raug tswj xyuas kom zoo los lav qhov ua tau zoo tshaj plaws rau nws qhov kev npaj siv. Carbon (C), manganese (Mn), phosphorus (P), sulfur (S), silicon (S), thiab cov kab ntawm lwm cov ntsiab lus, suav nrog txhuas (Al) thiab titanium (Ti), feem ntau ntawm nws cov tshuaj pleev ib ce. . P235GH muaj lub zog tsim nyog, ductility, thiab corrosion kuj vim nws cov tshuaj muaj pes tsawg leeg.

Mechanical Properties ntawm P235GH Siab Vessel Steel
Vim nws cov yam ntxwv zoo elongation, P235GH tuaj yeem tiv taus qhov kub thiab txias yam tsis muaj kev cuam tshuam loj heev. Tsis tas li ntawd, txawm nyob rau hauv qhov kub thiab txias, nws tswj nws cov neeg kho tshuab kev ncaj ncees, ua rau nws cov khoom zoo meej rau boilers thiab cov hlab ntsha siab.

Kev ua tau zoo heev yog ib qho ntawm P235GH qhov zoo tshaj plaws. Nws yog yooj yim weldable siv cov txheej txheem ib txwm zoo li kev siv vuam, roj-shielded arc vuam, thiab phau ntawv hlau arc vuam. Lub tshuab zoo ntawm cov hlau tsis cuam tshuam los ntawm vuam thaum ua kom raug thiab nrog cov ntaub ntawv muab tub lim zoo. P235GH yog cov khoom ntawm kev xaiv rau kev tsim cov hlab ntsha siab thiab boilers nrog intricate geometry vim nws weldability.
Kev kho cua sov ntawm P235GH Siab Vessel Steel
P235GH qhov kev ua tau zoo tau zoo heev los ntawm cov txheej txheem kho cua sov. Normalizing feem ntau yog siv los txhim kho cov hlau tag nrho toughness thiab ua kom zoo dua cov hlau cov nplej. Cov txheej txheem entails cua sov cov khoom saum toj no nws tseem ceeb kub ntau yam ua ntej txias nws nyob rau hauv tseem huab cua. Normalizing txo cov kev ntxhov siab sab hauv, boosts steel lub zog, thiab txhim kho cov khoom tiv thaiv rau nkig puas.
