Avantaj ak limit
Avantaj:
- Segondè fòs: S355MC ofri yon fòs sede segondè, ki fè li apwopriye pou aplikasyon pou chaj-pote.
- Ekselan soudabilite: Ka asye a fasil soude lè l sèvi avèk metòd konvansyonèl, ki enpòtan anpil pou konstriksyon ak fabwikasyon.
- Bon fòmabilite: Li ka fasilman fòme ak fòme, sa ki pèmèt pou aplikasyon versatile.
Limitasyon:
- Rezistans korozyon: Pandan ke li gen rezistans desan nan korozyon atmosferik, li ka mande pou kouch pwoteksyon nan anviwònman piman bouk.
- Tanperati sansiblite: Pwopriyete mekanik yo ka degrade nan tanperati ki wo, sa ki limite itilizasyon li nan aplikasyon pou tanperati ki wo -.
S355MC se lajman ki itilize nan konstriksyon an nan pon, bilding, ak eleman otomobil, reflete enpòtans li nan jeni modèn. Siyifikasyon istorik li se nan devlopman li kòm yon pati nan estanda Ewopeyen an pou asye estriktirèl, ki te fikse referans pou bon jan kalite ak pèfòmans.

FAQ
K: Ki fòs sede S355MC asye?
A: 355 MPa
Non klas S355MC refere a fòs sede anwo li yo. Sa a se 355 MPa.
K: Ki sa ki asye S355MC?
A: S355MC se yon cho -woule, segondè-fòs ki ba- alyaj asye. Li konbine gwo fòs ak fòmabilite eksepsyonèl ak bon jan kalite ki konsistan. Li ranplase asye konstriksyon konvansyonèl pou aplikasyon kote gwo fòs se esansyèl.
K: Kisa MC vle di nan S355MC?
A: "MC" nan deziyasyon an vle di "thermomechanically woule", ki vle di ke asye a pwodui pa yon pwosesis kontwole ki enplike chofaj ak woule nan tanperati ki wo yo pwodwi pwopriyete yo vle mekanik. Konpozisyon nan asye otomobil S355MC (%, analiz jete)
K: Ki diferans ki genyen ant s355j2 ak S355MC?
A: Nivo fòs: S355JR asye anjeneral gen yon fòs sede minimòm de 355MPa, ak fòs rupture li yo se 470-630MPa lè epesè a se mwens pase 16 mm. An konparezon, asye S355MC gen yon fòs sede ki pi wo, anjeneral 355-510MPa, ak yon fòs rupture nan 430-550MPa.
K: Ki ekivalan a S355MC?
A: S355mc ki dwe nan spesifikasyon nan nòm Euro nan EN 10149-2. En 10149-2 S355mc ekivalan se DIN, WNr QStE360TM, JIS SPFH540, ak Lafrans ki gen klas AFNOR E355D ak E390D. an Angletè se BS 46F35 ak BS 46F40, ak Itali ki gen klas UNI FeE355TM ak Espay montre klas UNE AE390HC.
