Q355 Umuyoboro Ushyushye Utagira Umuyoboro

Ibisobanuro bigufi:

Umuyoboro w'icyuma Q355 nu Bushinwa buke buvanze cyane imbaraga zicyuma zubatswe, zasimbuye Q345, ubucucike bwibintu ni 7,85 g / cm3.Ukurikije GB / T 1591 -2018, Q355 ifite urwego 3 rwiza: Q355B, Q355C na Q355D.

Q355 umuyoboro wibyuma ni umusemburo muke, ibyuma-bikomeye cyane bikoreshwa mubikoresho byo gusudira bishyigikira imihangayiko n'imitwaro iremereye.Q yerekana umusaruro, mugihe umubare 355 werekana imbaraga zumusaruro.

Ibiranga umuyoboro wa Q355

Q355 umuyoboro wibyuma nicyuma cyubatswe gifite imbaraga za 345 MPa nimbaraga zingana na 450 MPa.Ifite imikorere itangaje nimbaraga zo guhonyora, zishobora gukoreshwa mugukora imiyoboro yumuvuduko ukabije wa gaze irimo litiro 500.Q355 ifite kandi urwego rwo gukingira ingese.

Imikoreshereze ya Q355 Umuyoboro

Q355 umuyoboro wibyuma ufite imiterere yubukanishi, gusudira gukomeye, hamwe no kurwanya ruswa.Irashobora gukoreshwa mugukora no gukora ibigega bya peteroli, ubwato bwumuvuduko ukabije, amashyiga, amato, sitasiyo yamashanyarazi, nibindi bice byinshi byubaka imitwaro myinshi.

Ingano: 34mm-610mm.

WT: 3,5mm-50 mm.

Imiterere: Uruziga.

Ubwoko bw'umusaruro: Bishyushye cyangwa Bishyushye byakoreshejwe.

Uburebure: Uburebure bumwe butunguranye / Uburebure bwikubye kabiri cyangwa nkibisabwa umukiriya nyirizina uburebure bwa 12m

Kugororoka

Post annealing, ibicuruzwa byanyujijwe mumashini irindwi igorora kugirango igere neza neza.

Eddy

Inyandiko igororotse, buri tube inyuzwa mumashini ya eddy kugirango tumenye ibice byubuso nizindi nenge.Gusa imiyoboro inyura eddy ikwiranye no kugeza kubakiriya.

Kurangiza

Buri muyoboro usizwe amavuta yamavuta arwanya ruswa cyangwa yisize irangi kugirango arinde ubuso kandi arwanya ruswa nkuko abakiriya babisabwa, buri muyoboro wumuyoboro utwikiriwe na capitike ya plastike kugirango wirinde kwangirika kwambuka, ibimenyetso nibisobanuro bishyirwa kandi ibicuruzwa byiteguye koherezwa .
