ASTM A302 GR.B Mn-Mo Alloy Pressure Vessel Steel Plate

ASTM A302 yakajairwa dhizaini yekumanikidza ngarava mahwendefa mune alloy simbi, manganese molybdenum uye manganese-molybdenum-nickel.
ASTM A302 imhando yeyakaderera alloy simbi yakatarwa inovhara mana giredhi akasiyana (A, B, C, D), Giredhi C uye D ine kemikari inoumbwa Ni, nehupamhi hwakafanana, goho uye kusimba kweGiredhi C zvakafanana zveGiredhi. B, ukuwo elongation rate yegiredhi C iri pamusoro.
A302 Giredhi B simbi ndiro ichawanzo kupihwa mune iyo-yakakungurutswa mamiriro. Maplate anogona kuodha akajairwa kana kudzoreredzwa kushushikana, kana zvese zviri zviviri. Kana A 302 Giredhi B iri pamusoro pe50mm mukukora ichave yakajairika.
