SA387 GR.12 CL2 Pressure Vessel Steel plate

A387 Grade 12 CL 1, A387 Grade 12 CL 2 vari pasi pesimbi yakatarwa standard ASTM A387/A387M yekumanikidza mudziyo simbi mahwendefa, alloy simbi ine Chromium-Molybdenum.Iyo yakaenzana simbi ndiro SA387 Grade 12 CL 1 uye SA387 CL Grade 212 dziri pasi peAmerican steel stamdard SA 387/SA 387M. All these alloy steel plates akaitirwa kunyanya kune welded boilers and pressure vessels&tanks.Kutenderedza ukuru hwemandireta kunogumira chete nekugona kwezvakaumbwa kuti zvizadzise zvinodiwa nemakanika pfuma.
Yekumanikidza mudziyo simbi ndiro SA387 Giredhi 12 CL 1, iyo tensile simba ichave mukati me380 kusvika 550, shoma goho simba i230 Mpa.Ku SA387 Grade 12 CL 2 kumanikidza mudziyo simbi ndiro, iyo tensile simba iri pa450-585 Mpa uye goho. poindi ichave pamusoro pe275 Mpa. Kunze kwezvinhu zvishanu zvikuru, Cr-Mo iri zvakare mumakemikari ezvisimbi zvealloy.

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:

Giredhi	Tembiricha, °F [°C]
2, 12 uye 11	1150 [620]
22, 22L, 21, 21L uye 9	1250 [675]
