STPT 370ni urwego rw’ubusanzwe bwa JIS G 3456 yo mu Buyapani ku miyoboro y’icyuma cya karuboni, ikoreshwa ku miyoboro y’umuvuduko mu bidukikije bifite ubushyuhe buri hejuru ya 350°C. Ishobora kuba imiyoboro idafunze cyangwa ivanze hakoreshejwe uburyo bwo gusudira bukoresha amashanyarazi (ERW). Imiterere ya mekanike y’ibikoresho bya STPT 370 ni imbaraga nkeya zo gukurura za 370 MPa n’imbaraga nkeya zo gutanga umusaruro za 215 MPa.
Niba ushaka uruganda n'umucuruzi w'imiyoboro y'ibyuma byujuje ibisabwa na JIS G 3456, ni twe mufatanyabikorwa ushaka. Twandikire uyu munsi kandi tuzishimira kugufasha!
Bikwiriye uburebure bw'inyuma bwa mm 10.5 - mm 660.4 (6A - 650A) (1/8B - 26B).
A na B ni uburyo bubiri bwo kugaragaza umurambararo w’amazina mu gipimo cy’Abayapani. By’umwihariko, A ihuye na DN, mu gihe B ihuye na NPS.
JIS G 3456 STPT 370 ishobora gukorwa hakoreshejweumushororoinzira yo gukora cyangwagusudira hakoreshejwe amashanyaraziinzira (ERW).
Uburyo bwo gukora buhura kandi n'uburyo butandukanye bwo kurangiza kugira ngo buhangane n'ahantu hatandukanye ho gukoreshwa.

STPT 370 igomba kuba ishyushye.
1. Umuyoboro w'icyuma ushyushye kandi udafite umugozi: Uko byakozwe, gufunga cyangwa kuvugurura bishobora gukoreshwa uko bikenewe;
2. Umuyoboro w'icyuma ukozwe mu buryo bukonje kandi butarimo umugozi: Gufunga cyangwa kuvugurura ubushyuhe buke;
3. Umuyoboro w'icyuma ushyushye kandi udashobora gushyuha: Uko byakozwe, gufunga cyangwa kuvugurura bishobora gukoreshwa uko bikenewe;
4. Ifite ubushobozi bwo gukurura amashanyarazi bukozwe mu buryo bukonje kandi nk'umuyoboro w'icyuma ukozwe mu buryo bushyushye: Itera cyangwa ihindura ubushyuhe buri hasi.

Umutungo wo gusana
Ikwiriye imiyoboro ifite umurambararo wo hanze urenga mm 60.5.
Icyitegererezo gishyirwa hagati y'ibice bibiri hanyuma kigahinduka uburebure. Iyo intera iri hagati y'ibice bibiri igezeH, nta myenge iri ku buso bw'umuyoboro w'icyuma.

Gukomera
Ikwiriye imiyoboro y'icyuma ifite umurambararo wo hanze wa mm 60.5 cyangwa munsi yayo.
Iyo ingano y'ibipimo izungurutse ku gice cy'imbere cy'umurambararo ukubye inshuro esheshatu z'umurambararo w'inyuma w'umuyoboro, ingano y'ibipimo irasuzumwa kandi nta cyuho kiboneka.

Iyo umurambararo w'inyuma n'ubugari bw'urukuta by'umuyoboro w'icyuma bitari ingano isanzwe, uburyo bukurikira bushobora gukoreshwa kugira ngo hamenyekane urwego rukwiye rw'ibipimo:
Ubwa mbere, hitamo amanota asanzwe y’ingengabihe yegereye ingano idasanzwe; ubwa kabiri, menya amanota agenwe ubara agaciro ka P.

Kuva yashingwa mu 2014,Botop Steelyabaye ikigo gikomeye mu kugurisha imiyoboro y'icyuma cya karuboni mu majyaruguru y'Ubushinwa, kizwiho gutanga serivisi nziza, ibicuruzwa byiza, n'ibisubizo byuzuye.
Iyi kompanyi itanga imiyoboro itandukanye y’icyuma cya karuboni n’ibindi bifitanye isano, birimo imiyoboro y’icyuma idakora neza, ERW, LSAW, na SSAW, ndetse n’urutonde rwuzuye rw’imiyoboro n’ibice bifunganye. Ibicuruzwa byayo byihariye birimo kandi alloys nziza n’ibyuma bitarangirika bya austenitic, byakozwe kugira ngo bihuze n’ibikenewe mu mishinga itandukanye y’imiyoboro.
Mutwandikire kandi tuzishimira gusubiza ibibazo byanyu.
