ASTM A302 Giredhi A Mn-Mo Alloy Pressure Vessel Steel Plate

Iyi dhizaini inovhara manganese-molybdenum uye manganese-molybdenum-nickel alloy simbi mahwendefa akagadzirirwa kunyanya kune welded boilers uye mimwe midziyo yekumanikidza. ASTM A302 imhando yeyakaderera alloy simbi yakatarwa inovhara mana magiredhi akasiyana (A, B, C, D), Giredhi C uye D ine kemikari inoumbwa Ni, nehupamhi hwakafanana, goho uye kusimba kweGiredhi C zvakafanana zveGiredhi. B, nepo elongation rate yegiredhi C iri pamusoro.Iyi rondedzero inovhara manganese-molybdenum uye manganese-molybdenum-nickel alloy simbi mahwendefa akagadzirirwa kunyanya kune maboiler akaiswa uye mamwe midziyo yekumanikidza.
