Itandukaniro riri hagati ya Q235 na SS400 ni irihe?
Q235 na SS400 ni ibyuma bibiri by’imiterere ya karuboni bikoreshwa cyane, akenshi bifatwa nk’ibisa mu mikorere, ariko bikomoka ku bipimo bitandukanye by’igihugu kandi bifite itandukaniro rito mu miterere ya shimi n’imiterere ya mekanike. Q235 isobanurwa hakurikijwe ibipimo ngenderwaho bya GB/T 700 by’Ubushinwa, mu gihe SS400 ivugwa hakurikijwe ibipimo ngenderwaho bya JIS G3101 by’Ubuyapani. Nubwo bifite inkomoko itandukanye, bikunze gukoreshwa mu miterere imwe nk’ibiraro, inyubako, n’ibice by’imashini.
Mu rwego rwa shimi, Q235 na SS400 byombi ni ibyuma bifite karuboni nkeya, ahanini bigizwe n'icyuma gifite karuboni nkeya, manganese, fosifore, na sulfure. Q235 ubusanzwe ifite karuboni ntarengwa ya 0.22%, kandi imipaka ku bindi bintu ni minini cyane kugira ngo habeho uburyo bwo gusudira no guhindagurika neza. SS400 ifite imiterere isa ariko yemerera ko ibintu bimwe na bimwe bihinduka bitewe n'uburyo bikorwa. Iri tandukaniro akenshi riba rito, ariko mu bikorwa bimwe na bimwe—cyane cyane ibyo gusaba gusudira neza cyangwa icyemezo mpuzamahanga cy'ibikoresho—bishobora kuba ingenzi.
Mu buryo bwa tekiniki, Q235 yitiriwe imbaraga zayo zo gutanga umusaruro za 235 MPa, mu gihe SS400 itanga imbaraga zingana na zo zo gutanga umusaruro za 245 MPa. Imbaraga zazo zo gukurura nazo ziri ku rugero rumwe, muri rusange hagati ya 375 na 500 MPa. Kubera iyo mpamvu, ibyuma byombi bishobora gukora neza mu miterere y'inyubako kandi akenshi bikoreshwa mu buryo butandukanye iyo amahame yo mu gace abibemereye. Ariko, ni ngombwa kumenya ko gusimbuza ibikoresho bigomba kwemezwa buri gihe n'abahanga mu by'inyubako cyangwa inzego zishinzwe ibishushanyo mbonera, cyane cyane mu mishinga igenzurwa cyangwa iy'ingenzi ku mutekano.
Mu bijyanye n'ikoreshwa, Q235 ikunze kuboneka ku isoko ry'imbere mu Bushinwa kandi ikunze gutoranywa mu bwubatsi buhendutse no mu gukora ibintu muri rusange. SS400, kubera ko ari igipimo ngenderwaho cy'Abayapani, ikoreshwa cyane mu Buyapani no mu bindi bice bya Aziya. Iyo hari ubucuruzi mpuzamahanga, guhitamo hagati ya Q235 na SS400 bishobora guterwa no kuboneka kw'uruhererekane rw'ibicuruzwa, ibisabwa mu kwemeza, n'ibyo abakiriya bakunda. Amaherezo, nubwo Q235 na SS400 bisa mu buryo bwinshi, kumenya itandukaniro ryabyo rito bituma habaho gufata ibyemezo byiza mu guhitamo ibikoresho.
