Icyuma Q195, Q235, itandukaniro mubikoresho?

Ni irihe tandukaniro riri hagati ya Q195, Q215, Q235, Q255 na Q275 mubijyanye nibikoresho?

Icyuma cya karubone ni ibyuma byinshi byakoreshejwe cyane, umwirondoro nibyimwimuro ndetse numwiyumirwa, muri rusange bidakeneye gukoreshwa mu buryo butaziguye, cyane cyane kumiterere rusange nubwubatsi.

Q195, Q215, Q235, Q255 na Q275, nibindi. , B, c, d) uburyo bwa Deoxyenine bwibimenyetso nibindi ku bice bine byibigize. Kuva ku miti, amanota yicyuma yoroheje Q195, Q215, Q255, Q255 na Q275 nibirimo bya karubone, ibirimo bya Mangane, biragenda neza. Imashini ya mashini kuva mumanota, amanota yavuzwe haruguru yerekana ko ubunini ≤ 16mm yumusaruro ingingo ya sit. Imbaraga za kanseri zayo zari: 315-430, 335-450, 375-500, 410-550, 490-630 (obn / mm2); qi kurengera kwayo: 33, 31, 26, 24, 20 (0.5%). Kubwibyo, mugihe itangiza ibyuma kubakiriya, abakiriya bagomba kwibutswa kugura ibikoresho bitandukanye byubyuma ukurikije ibikoresho bisabwa, kugirango bidahinduka ubuziranenge bwibicuruzwa.

 

Ni irihe tandukaniro riri hagati ya Q235a ibikoresho bya Q235 na Q235B?

Q235a na Q235b ni ibyuma bya karubone. Muri GB7 10008-88, Q235A na Q235b itandukaniro ryibintu birimo karubone, ibikoresho bya karubone, ibikoresho bya karubone ya Q235A muri 0.14-02% hagati; Q235b ibikoresho ntabwo ikora ikizamini cyingaruka, ariko akenshi kora ubushyuhe bworoshye bwo gukora ikizamini, V-noch. Kugereranya neza, imitungo ya mashini yibikoresho Q235B iruta kure kuruta ibikoresho Q235A. Muri rusange, urusyo rw'icyuma mumwirondoro barangije mbere yo kuva mu ruganda rurangwa ku isahani iranga. Abakoresha barashobora kuvuga niba ibikoresho ari Q235a, Q235b, cyangwa ibindi bikoresho kuri plaque.

 

Amanota y'ibyuma y'Abayapani ni SPHC, SVHD, n'ibindi. Bisobanura iki?

Ibyuma byabayapani (urukurikirane rwa JIS) Icyuma gisanzwe cyibanze cyane: Igice cya mbere cyerekana ibikoresho, nka: s (st (ferrum) bisobanura fer. Igice cya kabiri cyimiterere itandukanye, ubwoko, gukoresha, nka p (isahani) iyo plate, t (tube), k (koge) icyo gikoresho. Igice cya gatatu cyimbonerahamwe kiranga umubare, muri rusange imbaraga ntoya. Nka: SS400 - iyambere s ibyuma (Ssteel), icya kabiri s "imiterere" (imiterere), 400 kumurongo wo hasi wa 400mpa steel. Muri bo: SPHC ------ Icyapa cyambere cya Ssteel, p Ku isahani ahinnye, impfunya amagambo y'ubushyuhe, amagambo y'ubushyuhe, byose byerekana ko muri rusange.

 

SVHD ----- yerekana urupapuro rushyushye rwicyuma hanyuma wambure kashe.

SPHE ------ yerekana impapuro zishyushye zishyushye kandi zikangura igishushanyo cyimbitse.

SPCC ------ yerekana imbeho zikonje za karubone zizunguruka kandi zihuza imikoreshereze rusange, bihwanye nubushinwa Q195-215A amanota. Inyuguti ya gatatu C ni amagambo ahinnye yubukonje, asabwa kugirango ikizamini cya tensile kurangiza amanota wongeyeho t for spcct.

SPCD ------ yerekana imbeho ikonje ya karubone yijimye kandi ihwanye no gukubita, bihwanye nubushinwa 08al (13237) Icyuma cyuzuye cya karubone.

Spce ------ yerekana imbeho zikonje zizunguruka zishushanyije kandi zishushanya igishushanyo cyimbitse, bihwanye nubushinwa 08al (5213) gukubita ibyuma. Kugirango ubone imikorere, ongeraho n kuri grocen kumpera yicyiciro.

Ubukonje buzunguruka urupapuro rwabigenewe kandi busanzwe bwo kwerekana, budashijwe kuri a, gukandaba ibisanzwe kuri s, 1/8 bigoye kuri 8, 1/4 birakomeye kuri 4, 1/2 birakomeye kuri 2.

Ubuso buringaniye: Nta Gress Kurangiza D, Gloss Kurangiza B. Nka SPCCT-SD yerekana amateka asanzwe Noneho spcct-sb yerekana amateka yimiterere, yarangiye, imbeho yazunguye karubone hamwe nimiterere yishingiwe.
