ASME SA333 Gr. 6 Ubushyuhe Buke Bidafite Umuyoboro

ASTM A333Gr6 / ASME SA333Gr6 Umuyoboro wubushyuhe buke
ibicuruzwa bisabwa
Icyiciro: A333Gr.6 / SA333Gr.6
Bisanzwe: ASTM A333 / ASME SA333

inzira yo gukora ibyuma
Igikorwa cyo gukora imiyoboro yicyuma gishyirwa mubikorwa hifashishijwe sisitemu yikoranabuhanga ya 20G ibyuma.

Gutandukanya ibyuma byerekana ibyuma no gutandukana ibiro
Gutandukana kwa diameter yo hanze: Gutandukana kwa diameter yo hanze yumuyoboro wibyuma bigomba kuba byujuje ibisabwa

Ikigereranyo cya diameter (mm)	10.3~48.3	> 48.3 ~ 114.3	> 114.3 ~ 219.1	> 219.1 ~ 406.4
Gutandukana kwa diameter (mm)	-0.8~+0.4	-0.8~+0.8	-0.8~+1.6	-0.8~+2.4

Gutandukana k'urukuta: -8% ~ + 12%.
Gutandukanya ibiro: -3.5% ~ + 10%.
Uburebure buhamye: ukurikije ibyo ukoresha asabwa.
Kugororoka: .51.5mm / m.
Imiterere yo gutanga hamwe nuburyo bwo gutunganya ubushyuhe bwicyuma
Umuyoboro wibyuma utangwa muburyo busanzwe bwubushyuhe.
Uburyo busanzwe bwo gutunganya ubushyuhe bwibicuruzwa byarangiye ni: 900 ° C ~ 930 ° C kuri 5 ~ 15min, gukonjesha ikirere.

Ibikoresho bya mashini yimiyoboro yicyuma
Imiterere ya Tensile
Imiterere ihindagurika yimiyoboro yicyuma igomba kuba yujuje ibisabwa na ASTM A333Gr6.
Ku miyoboro y'ibyuma ifite uburebure bw'urukuta nomero mm 8mm, ikizamini cya tensile ni urugero rurerure rwo kugerageza rufite ubugari bwa 12.5mm n'uburebure bwa 50mm. Ku miyoboro y'ibyuma ifite uburebure bw'urukuta nomero 8mm, hashobora gukoreshwa urugero ruzengurutse rufite intera ya 4D.

Ikizamini
Ikintu kimenagura ni 0.07.

Ingaruka
Buri cyiciro cy'imiyoboro y'icyuma gifite diameter yo hejuru irenga 21.3mm igomba kugenzurwa kugirango ikore ingaruka Akv.

Kugereranya ubunini (mm)		3	3.3	4	5	6	6.67	7	7.5	8	9	10
Akv (J)	≥ 5	≥ 6	≥ 7	≥ 8	≥ 9	≥11	≥ 12	≥13	≥ 14	≥16	≥17	≥18

Ingaruka yubushyuhe
Iyo ubunini bwurugero ruto ruto rugeze cyangwa rurenze 80% byubugari nyabwo bwumuyoboro wibyuma, ubushyuhe bwikizamini ni -45 ° C.
Iyo ubunini bwurugero ruto ruto ruri munsi ya 80% yubugari nyabwo bwumuyoboro wibyuma, ubunini bwikigereranyo bugomba kuba bunini bushoboka. Ubushyuhe bwikizamini bwari -55 ° C.


Ikizamini gikomeye (gusa iyo bisabwa n'amasezerano)
Niba amasezerano asaba ubukana bwo gupimwa hakurikijwe NACE MR-0175, igipimo cyikigereranyo cya mm 20-30 z'uburebure kizafatwa kuri buri cyiciro cyimiyoboro yicyuma, kandi ubukana ntibuzaba munsi ya 22HRc.
