Q355 steel khoom
Q355Khoom Description
Q355 steel yog lub zog muaj zog steel nrog ntau yam zoo uas ua rau nws tsim nyog rau ntau yam kev siv. Qhov zoo ntawm Q355 steel txawv nyob ntawm qhov sib txawv lossis hom, xws li Q355B, Q355C, Q355D, lossis Q355E. Txawm li cas los xij, feem ntau, hauv qab no yog qee qhov tseem ceeb ntsig txog Q355 steel:
Siab zog
Q355 steel muaj npe nrov rau nws lub zog loj, nrog qhov tsawg kawg nkaus tawm lub zog ntawm 355 MPa. Qhov no tso cai rau nws ua siab ntev loads thiab strains, ua rau nws zoo tagnrho rau cov qauv siv hauv tsev thiab engineering.
Weldability zoo
Q355 steel muaj zog weldability, uas tso cai rau yooj yim koom thiab ntau lawm txheej txheem. Nws tuaj yeem welded siv cov txheej txheem txheej txheem xws li arc vuam, roj vuam, thiab vuam tsis kam, ntxiv rau nws ntau yam thiab yooj yim ntawm kev siv.
Zoo heev Formability
Q355 steel muaj qhov zoo formability, uas txhais tau hais tias nws tuaj yeem khoov tau yooj yim thiab tsim rau ntau yam khoom siv. Cov yam ntxwv no muab kev tsim qauv yooj yim dua thiab kev tsim cov txheej txheem nyuaj.
Txhim kho Toughness
Q355 steel muaj zoo toughness, uas yog lub peev xwm los nqus lub zog thiab tiv thaiv puas. Cov yam ntxwv no txhais tau hais tias cov hlau tuaj yeem dais qhov cuam tshuam thiab dynamic loads yam tsis muaj nkig tsis ua hauj lwm, ua rau nws zoo tagnrho rau cov kev siv uas yuav tsum tau durability.
Zoo Ductility
Q355 steel muaj zog ductility, uas tso cai rau nws mus deformed yam tsis muaj pob txha. Cov yam ntxwv no yog qhov tseem ceeb rau cov khoom siv vim nws tso cai rau cov hlau yuav khoov, ncab, lossis molded thaum tuav nws txoj kev ncaj ncees.
Impact Resistance
Q355 steel muaj qhov cuam tshuam zoo, ua rau nws tsim nyog rau cov ntawv thov uas muaj kev cuam tshuam sai thiab siab. Nws tuaj yeem ua rau muaj kev ntxhov siab sai thiab nqus lub zog yam tsis muaj qhov ua tsis tiav, uas yog qhov tseem ceeb hauv kev tsim kho uas yuav ntsib cov loads dynamic lossis vibrations.
Huab cua Resistance
Qee yam ntawm Q355 steel, xws li Q355E, tuaj yeem txhim kho huab cua tiv thaiv vim qhov sib ntxiv ntawm cov khoom siv alloying. Cov yam ntxwv no tso cai rau cov hlau ua kom muaj kev tiv thaiv corrosive ib puag ncig, ua rau nws tsim nyog rau kev siv sab nraum zoov lossis hauv dej hiav txwv.
