Pwodwi Aplikasyon
Konstriksyon pon:
Ideyal pou bati pon nan tout trave ak desen, bay fòs esansyèl ak rezistans pou travès, pil, ak sipò.
Enfrastrikti gran wout:
Yo itilize anpil nan pwojè gran wout pou amelyore sekirite ak pèfòmans alontèm -nan kondisyon metewolojik ekstrèm.
Pon tren yo:
Apwopriye pou konstriksyon pon tren, sipòte chay lou epi asire transpò serye.
Enfrastrikti iben:
Travay nan pon pou pyeton, pasaj siperyè, ak wout ki wo pou amelyore mobilite iben.
Estrikti ki reziste -Korozyon:
Klas tankou 50W ak HPS 50W yo fèt pou pon ki ekspoze nan anviwònman maren oswa endistriyèl, pwolonje lavi sèvis ak diminye depans antretyen.
Konpozan estriktirèl pi lwen pase pon yo:
Aplike nan bilding, estad, ak estrikti endistriyèl kote gwo -fòs, asye dirab nesesè.
Ki sa ki A709 klas 50W asye?
ASTM A709-50W seyon spesifikasyon estanda pou asye estriktirèl prensipalman nan fabwikasyon an nan pon asye. ASTM A709-50W kouvri gwo fòs, ba pèmèt fòm estriktirèl asye, plak ak ba.
Ki klas ASTM A709 asye?
ASTM A709 la se spesifikasyon estanda pou asye estriktirèl pou pon epi li gen ladan kabòn, segondè -fòs ki ba- alyaj, ak asye alyaj trempe ak tanperaman yo itilize kòm plak estriktirèl nan konstriksyon an nan pon yo. SSAB ofri senk klas sa yo nan A709;36, 50, 50W, HPS 50W ak HPS 70W.
Ki diferans ki genyen ant ASTM A572 Klas 50 ak ASTM A709 Klas 50?
A572 Klas 50: Itilize nan yon pakèt aplikasyon estriktirèl, tankou bilding, gwo fò tou won transmisyon, ekipman, ak konstriksyon jeneral. Li pa espesyalman optimize pou pon yo. A709 Klas 50: Prensipalman yo itilize pou konstriksyon pon ak lòt estrikti kote rezistans amelyore ak soudabilite yo enpòtan.
Ki fòs sede ASTM A709 klas 50?
Klas 50 asye nan spesifikasyon sa a mande pou yon fòs sede minimòm de 50 ksi. Itilize kòm manm estriktirèl nan bilding pon oswa pou estrikti menm jan an.
Ki diferans ki genyen ant ASTM A36 ak A709?
ASTM A709 klas 36 se yon materyèl pon kote kabòn ajoute nan fòs ak hardenability nan asye a.A36 gen mwens pase0. 30% kabòn e konsa, pa posede gwo hardenability. Plak asye ASTM A709 klas 36 amelyore rezistans korozyon epi yo ka itilize nan aplikasyon deyò.
Ki sa ki ekivalan ASTM A572 klas 50?
ASTM A572 Klas 50 ekivalan a plizyè lòt klas asye, ak ekivalan entènasyonal ki pi komen yo se S355JR (estanda Ewopeyen an) ak Q345B (estanda Chinwa). Pi bon ekivalan a depann sou kondisyon espesifik pwojè yo, kidonk li toujou pi bon pou konsilte espesifikasyon materyèl ak yon espesyalis pou konfime konpatibilite.
Ki diferans ki genyen ant ASTM A36 ak ASTM A572 GR 50?
Kòm mansyone pi bonè,A36 se asye ki gen yon fòs sede minimòm de 36,000 PSI. Klas sa a soti fòs li nan yon konbinezon kabòn ak Manganèz. Nan lòt men an, A572-50, pou egzanp, se yon kalite asye ak yon fòs sede minimòm de 50,000 PSI.
Ki diferans ki genyen ant A572 ak s355?
An rezime, tou de ASTM A572 Klas 50 ak S355JR yo se chwa ekselan pou aplikasyon asye estriktirèl, akASTM A572 Klas 50 bay pi gwo kapasite fòs ak S355JR ofri adaptabilite ak itilizasyon toupatou nan pwojè konstriksyon Ewopeyen an..
Èske A572 asye korozyon reziste?
A572 asye se tipikman itilize nan aplikasyon estriktirèl akòz gwo fòs li yo, duktilite, soudabilite akrezistans korozyon. Aplikasyon sa yo gen ladan seksyon estriktirèl, ba ranfòsman, pon, gratsyèl ak kay.
