Diferans ki genyen ant asye Q345D ak asye Q355D
Q345 asye se yon estanda Chinwa ki ba alyaj segondè fòs estriktirèl asye, ak deziyasyon an nan "Q" ki reprezante fòs nan sede ak nimewo a ki endike fòs la sede minimòm. Q345 asye gen bon pwopriyete mekanik, pèfòmans tanperati ki ba, plastisit, ak soudabilite. Li se lajman ki itilize nan pon, machin, bato, bilding, veso presyon, elatriye.
Konpozisyon chimik Q345 asye anjeneral gen ladan eleman tankou kabòn, Silisyòm, Manganèz, fosfò, souf, chromium, nikèl, ak lòt eleman tras. Fòs sede li se jeneralman ant 345 MPa ak 500 MPa, tou depann de epesè ak kondisyon tretman chalè. Fòs rupture nan Q345 asye ka varye ant 470 MPa ak 630 MPa.
Q345D asye akQ355D asye yo tou de klas Chinwa ki ba alyaj segondè fòs estriktirèl asye, ak diferans prensipal la ke yo te fòs sede yo.
Q345D asye gen yon fòs sede nan 345 MPa, pandan y ap Q355D asye gen yon fòs sede nan 355 MPa. Sa vle di ke Q355D asye gen yon fòs sede yon ti kras pi wo epi jeneralman konsidere kòm yon materyèl ki pi fò pase Q345D.
An tèm de konpozisyon chimik, tou de klas asye yo sanble ak eleman tankou kabòn, Silisyòm, Manganèz, fosfò, souf, chromium, nikèl, ak lòt eleman tras. Yo gen tou bon pwopriyete mekanik, pèfòmans tanperati ba-, plastisit, ak soudabilite.
Tou de Q345D ak Q355D asye yo souvan itilize nan yon varyete aplikasyon tankou pon, bilding, machin, ak machin, pami lòt moun. Chwa ki genyen ant de la pral depann de kondisyon espesifik aplikasyon an ak nivo fòs ki nesesè.

Ki konpozisyon materyèl Q345?
Q345 a se yon asye akmwens pase 0.2 pousan nan konpozisyon li yo fèt ak kabòn, mwens pase 0.55 pousan nan konpozisyon li yo te fè nan Silisyòm ak plizyè enpurte. Sa a klas patikilye nan asye se yon objektif jeneral fabrikasyon asye nan jaden ekipman konstriksyon.
Ki sa ki ekivalan asye Q355D a?
Materyèl asye Q355D ekivalan aS355J2 materyèl asyenan spesifikasyon Ewopeyen an EN 10025-2.
