Igiciro cy'uruganda 304 cyangwa 316 Umunyururu usanzwe w'icyuma gifunga/umunyururu wo kuzamura Ishusho igaragara

Ibisobanuro bigufi:

Iminyururu ya SCIC yo mu rwego rwa 80 (G80) yo guterura ikorwa hakurikijwe ibipimo ngenderwaho bya EN 818-2, hamwe n'icyuma cya nickel chromium molybdenum manganese alloy steel hakurikijwe ibipimo ngenderwaho bya DIN 17115; gusudira no gutunganya ubushyuhe byakozwe neza kandi bigakurikiranwa neza bireba imiterere y'iminyururu harimo imbaraga zo gupima, imbaraga zo gucika, kurekura no gukomera.

Icyiciro

Guterura no gufunga, umunyururu, umunyururu mugufi, guterura umunyururu uzunguruka, umunyururu wa Grade 80, umunyururu wa G80, umunyururu uhuzwa, iminyururu yo gupfuka, umunyururu wa DIN 818-2 wo kwihanganira iminyururu yo gupfuka Umunyururu wa Grade 8, umunyururu w'icyuma gikozwe mu cyuma

Porogaramu

Guterura no gukurura imitsi, guterura imizigo, gufata imizigo

Nk’uruganda rukora imiyoboro y’ibyuma bizunguruka mu gihe cy’imyaka 30, uruganda rwacu rumaze igihe kinini rukora kandi rukora mu gihe cy’ingenzi cy’iterambere ry’inganda z’abashinwa mu bijyanye no gucukura imiyoboro y’amashanyarazi (cyane cyane ibirombe by’amakara), guterura ibintu biremereye, no gutwara ibintu mu nganda ku miyoboro y’ibyuma bizunguruka ifite imbaraga nyinshi. Ntiduhagarara ku kuba uruganda rukora imiyoboro y’ibyuma bizunguruka mu Bushinwa (rutanga toni zirenga 10.000 buri mwaka), ahubwo dukomeza guhanga no guhanga udushya tudahagarara.
