SA387 GR.21 CL1 Dzvinyiriro mudziyo simbi ndiro

ASTM A387 Gr 21 CL 1 i chromium molybdenum alloy simbi ndiro inoitirwa kunyanya kune welded boiler uye midziyo yekumanikidza yakagadzirwa neakakwira tembiricha sevhisi. Iyo Cr yemukati 3.00% uye iyo Mo yemukati 1.00%. Giredhi rega rega kunze kwegiredhi 21L, Grade 22L, Grade 91 uye Grade 911 rinowanikwa mumakirasi maviri etensile simba mazinga.ASTM A387 GRADE 5 Kirasi 1 - Alloy steelASTM A387 GRADE 5 Kirasi 1 A yemhando yepamusoro ASTM A387 GRADE 5 Kirasi 1 kana chrome molyb alloy simbi ndiro yakanangidzirwa kuti ishandiswe mune weldable kabhoni simbi yekumanikidza midziyo pane yakakwirira tembiricha.

Kurapa Kupisa kweSA387 Chrom Moly Alloy Steel Plate

Chrome moly alloy simbi ndiro iri pasi peASME SA387 ichauraiwa simbi, ichibatwa nemoto kungave nekupinzwa, kujaira uye kudziya. Kana kuti kana yakabvumiranwa nemutengi, yakawedzera kutonhora kubva pakupisa kweaostenitizing nekuputika kwemhepo kana kudzima mvura, kuchiteverwa nekupisa, tembiricha yekudziya shoma ichave sepatafura:
