Ibikoresho bya SS400 ni iki? Ni ikihe gipimo cy'icyuma cyo mu rugo gihuye na SS400?

SS400ni icyuma gisanzwe cyo mu Buyapani gikozwe mu byuma bya karuboni gihuye na JIS G3101. Gihuye na Q235B mu gipimo cy’igihugu cy’Ubushinwa, gifite imbaraga zo gukurura za 400 MPa. Bitewe n’uko gifite karuboni iringaniye, gitanga imiterere ikwiye, kikagira imikoranire myiza hagati y’imbaraga, ubushobozi bwo kugenda, no gusudira, bigatuma kiba icya mbere gikoreshwa cyane.
Itandukaniro riri hagati yaQ235b Ss400:

Amahame Atandukanye:
Q235Bikurikiza Standard National Standard y'Abashinwa (GB/T700-2006). "Q" yerekana imbaraga z'umusaruro, '235' igaragaza imbaraga z'umusaruro nibura 235 MPa, naho "B" ikagaragaza urwego rw'ubuziranenge. SS400 ikurikiza Standard y'Ubuyapani y'Inganda (JIS G3101), aho "SS" isobanura icyuma cy'ubwubatsi naho "400" ikagaragaza imbaraga z'umusaruro zirenga 400 MPa. Mu ngero z'icyuma za 16mm, SS400 igaragaza imbaraga z'umusaruro 10 MPa ziruta Q235A. Ingufu zombi zo gukurura no kurekura ziruta iza Q235A.

 

Ibiranga Imikorere:

Mu bikorwa bifatika, imiterere yombi igaragaza imikorere imwe kandi akenshi igurishwa kandi igatunganywa nk'icyuma gisanzwe cya karuboni, aho itandukaniro ritagaragara cyane. Ariko, ukurikije ibisobanuro bisanzwe, Q235B yibanda ku mbaraga z'umusaruro, mu gihe SS400 ishyira imbere imbaraga zo gukurura. Ku mishinga ifite ibisabwa birambuye ku miterere y'icyuma, guhitamo bigomba gushingira ku bikenewe byihariye.

 

Ibyuma bya Q235A bifite intera ntoya kurusha SS400. SS400 ingana na Q235 yo mu Bushinwa (ingana n'ikoreshwa rya Q235A). Ariko, ibimenyetso byihariye biratandukanye: Q235 igaragaza aho ibipimo bigarukira ku bintu nka C, Si, Mn, S, na P, mu gihe SS400 isaba gusa S na P kuba munsi ya 0.050. Q235 ifite imbaraga zo gutanga umusaruro zirenga 235 MPa, mu gihe SS400 igera kuri 245 MPa. SS400 (icyuma cy'imiterere rusange) yerekeza ku cyuma rusange gifite imbaraga zo gukurura zirenga 400 MPa. Q235 yerekeza ku cyuma gisanzwe cy'imiterere ya karuboni gifite imbaraga zo gutanga umusaruro zirenga 235 MPa.

 

Imikoreshereze ya SS400: SS400 ikunze kuzungurutswa mu nsinga, mu nsinga zizengurutse, mu nsinga kare, mu nsinga zirambuye, mu nsinga z'inguni, mu nsinga za I, mu bice by'imiyoboro, mu byuma bitanga amadirishya, no mu bindi bipimo by'imiterere, ndetse no mu nyubako z'ubugari buringaniye. Ikoreshwa cyane mu biraro, mu bwato, mu modoka, mu nyubako, no mu nyubako z'ubuhanga. Ikoreshwa nk'insinga zikomeza cyangwa mu kubaka ibisenge by'uruganda, iminara yo koherezamo ingufu nyinshi, mu biraro, mu modoka, mu byuma bitanga umuriro, mu byuma, mu byuma bitanga umuriro, mu bwato, nibindi. Ikoreshwa cyane mu bice bya mekanike bifite ibisabwa mu mikorere idakomeye. Ibyuma bya Grade C na D nabyo bishobora gukoreshwa mu bikorwa bimwe na bimwe byihariye.
