GNEE founi ASTM A302Gr.B plak asye ak A302 Klas B presyon veso asye plak. ASTM A302GRB se manganèz -molybdène- nikèl alyaj plak asye.
- Mo kle: ASTM A302GR.B, A302 Klas B, A302 Gr.B plak asye, ASTM A302GrB plak asye
- Adopte estanda: A 302/A 302M-03
- Vann klas asye: A302 Klas A, A302 Klas B, A302 Klas C, A302 Klas D klas asye
A302 Klas B plak asye spesifikasyon estanda pou plak veso presyon nan asye alyaj, manganèz molybdène ak manganèz -molybdène- nikèl.
A302 Klas B klas asye se min fòs sede nan 310Mpa. GNEE tou bay tès la ultrasons nan epesè nan A435 / A435M, A577 / 577M ak A578 / A578M pwomèt bon jan kalite a pafè nan koperasyon long.
Plak asye A302 Klas B yo dwe nòmalman apwovizyone nan kondisyon kòm -woule. Plak yo ka kòmande nòmalize oswa soulaje estrès, oswa toude. Si plak asye A302 Klas B pi wo pase 50mm nan epesè yo pral nòmalize.

Nwayo pèfòmans Avantaj nan A302 GrB presyon veso Steel Plak
Ekselan -Direte tanperati ki ba
Plak asye alyaj A302 GrB fèt pou fè byen nan anviwònman tanperati ki ba -. Sa a se youn nan rezon prensipal li lajman itilize nan aplikasyon pou veso presyon ki enplike kondisyon kriyojenik. Plak asye a kenbe severite li yo ak rezistans enpak menm nan tanperati osi ba ke -40 degre, sa ki fè li yon chwa ideyal pou tank depo ba-tanperati ak veso presyon.
Segondè fòs ak rezistans
A302 GrB plak asye woule cho gen gwo fòs rupture, ki fè li apwopriye pou anviwònman presyon wo -. Kapasite materyèl la pou kenbe tèt ak kondisyon presyon ekstrèm san echèk esansyèl nan endistri tankou jenerasyon pouvwa ak pwodiksyon pétrochimique, kote veso presyon yo ekspoze a gwo estrès entèn yo.
Rezistans korozyon
A302 GrB presyon veso asye plak ofri bon rezistans nan korozyon atmosferik, espesyalman lè ekspoze a anviwònman modere. Li kapab manyen ekspoze modere nan sibstans ki sou korozivite, fè li apwopriye pou itilize nan pwosesis chimik ak endistri petwochimik.
Pri-Efikasite ak Disponibilite
Plak asye chodyè A302 GrB gen yon pri ki pi ba pase kèk asye alyaj ki wo -, tankou 9% asye nikèl oswa segondè- asye pur. Sa fè li yon chwa pri-efikas pou aplikasyon kote pèfòmans ekstrèm materyèl alyaj ki pi wo-pa nesesè.
