Intsimbi yeCorten B

Intsimbi yeCorten B
I-ASTM Corten B ibakala lensimbi yimveliso eshushu eqengqelekayo yeentsimbi zesakhiwo kwiimeko zokunikezelwa kwezobugcisa kunye nokuphuculwa kwe-corrosion resistance.Inqanaba lentsimbi i-Corten B ihambelana nomgangatho we-ASTM onegunya lokuvunwa kwe-355MPa kunye ne-345MPa esekelwe kubukhulu obuhlukeneyo.
I-Corten B - intsimbi enganyangekiyo kwimozulu ekulungele ngakumbi ukusinda kunye nezakhiwo zokuthwala.
Izinto eziphathekayo zenza umaleko wayo wokukhusela xa zibonakaliswe kwizinto ze-atmospheric. Ngokusisiseko, umaleko ongaphezulu udla umhlwa othi emva koko ukhusele intsimbi engaphantsi kwawo. Ukugqitywa kwendalo akuqhelekanga ukuba kufuneke naluphi na uhlobo lokugcinwa okufana nokupeyinta, okwenza ukuba izinto eziphathekayo zibe yindleko ephezulu kwezinye iintsimbi zesakhiwo.
Ukupeyinta kunye nokugcinwa kuya kufuneka ukuba isakhiwo sihlala simanzi njengoko umaleko wokukhusela awuyi kubumba. Umzekelo omhle kulapho isiseko sesakhiwo sidibana nomhlaba okanye sintywiliselwe ngokuyinxenye.

I-ASTM Corten B yentsimbi iimpawu zoomatshini:
Kwiqondo lobushushu begumbi kwiipleyiti ≥3mm ngobukhulu (iisampuli zovavanyo olunqamlezayo, ngokwe-EN 10002). Iimfuno kwiipleyiti ezishushu ezigoqiweyo ≤3mm ubukhulu ngokwe-EN 10025-5.

Amandla empembelelo amiselwa kwisampulu zovavanyo lwe-ISO-V longitudinal kwiqondo lobushushu elingama-20°C njengomndilili weemvavanyo ezintathu. Ubukhulu bemveliso ≥10mm ixabiso eliqhelekileyo liyi-27 J. Kubunzima obuphakathi kwe-10mm kunye ne-6mm, ixabiso elincinci leempembelelo liyancitshiswa ngokulinganayo kwi-specimen ububanzi (ubukhulu bemveliso).
