Imiterere y'icyuma ya ASTM A992, A572, A283, A913: Itandukaniro ry'ingenzi ku isoko ry'imiterere y'icyuma ku isi

Muri iki gihe, guhitamo urwego rukwiye rw'icyuma ni ingenzi cyane ku buziranenge bw'inyubako, ubukorikori, n'ikiguzi cy'umushinga muri rusange mu nganda z'ubwubatsi. Dukurikije amahame y'Abanyamerika hari urwego rune rusanzwe rw'icyuma.ibyuma by'ubwubatsi bya ASTM A992, A572, A283 na A913Buri kimwe muri ibi byuma gifite urwego rutandukanye rw'imikorere n'ibisabwa mu mushinga.

Itandukaniro ry'ibikoresho n'iry'imashini

ASTM A992
Icyiciro: Icyuma cy'ubwubatsi gifite imbaraga nyinshi kandi giciriritse (HSLA)
Umuvuduko muto: 345 MPa (50 ksi) imbaraga zo gutanga umusaruro
Ikiranga: Imiterere y'ibikoresho byo gusukamo ibintu bikoreshwa mu gusukamo ibintu bifitanye isano n'imihangayiko igenzurwa cyane kugira ngo bibe bihuye neza kandi bikomeye.
Imiterere y'ingenzi: Yakorewe by'umwihariko icyuma gishyushye cyometseho umugozi munini (W/H beam).
A992 ni icyuma gisanzwe gikomeye muri Amerika ya Ruguru cyo kubaka ibyuma bikozwe mu buryo bwa frame.

ASTM A572
Icyiciro: Icyuma cy'ubwubatsi gifite imbaraga nke (HSLA)
Amanota: 42, 50, 55, 60, 65
Urwego rw'imbaraga: Ruruta icyuma gisanzwe cya karuboni.
Ibikoresho: Amasahani, inguni, imiyoboro, imirasire n'ibindi
Amanota yo hasi (Icyiciro cya 42,50) ashobora gusudira hakoreshejwe uburyo busanzwe bwo gusudira, Amanota yo hejuru (Icyiciro cya 65) akeneye uburyo bwihariye bwo gusudira cyangwa isuzuma ryinshi nka PWHT nibindi.

ASTM A283
Ubwoko: Icyuma cyubatswe na karuboni (icyuma cyoroshye)
Amanota: ABCD = Irahari
Ingufu: Ifite intege nke kurusha A572 na A992
Ushobora kuvuga ko byari nko kurema no gusudira umwana w'inzovu ku giciro cy'inzovu ikuze.
ASTM A283 yoroheje gusa ni yo igenewe gukoreshwa n'inyubako zitari iz'ingenzi.

ASTM A913
Ubwoko: Ibyuma bikomeye kandi bidafite aloyi nyinshi hakoreshejwe uburyo bwa QST (kuzimya no kwiyishyushya)
Amanota: 50, 65, 70 =Araboneka
Ikiranga: Ingufu nyinshi, gukomera gukomeye no gusudira neza mu cyuma gikomeye cyane.
Ishusho nyamukuru y'imitako minini kandi iremereye y'urukiramende rugari
A913 ikoreshwa cyane aho ibice bikomeye kandi byoroshye ari ingenzi mu nyubako nini kandi ndende z’icyuma.

Itandukaniro mu mikoreshereze

ASTM A992
Inyubako z'ubucuruzi n'iz'ibyuma by'amazu
Amadirishya y'inyubako ndende n'iziciriritse
Inyubako z'inganda n'iz'ibicuruzwa
Impamvu: Ishobora kwiringirwa neza kandi igasudira byoroshye, ikoreshwa ku mubiri w'imodoka.

ASTM A572
Ibiraro
Inganda
Iminara n'ibikoresho by'ingufu
Imbuga nini
Impamvu: Injeniyeri mu by'ubwubatsi zishobora kunoza uburinganire hagati y'imbaraga n'igiciro hamwe n'amanota menshi.

ASTM A283
Inyubako ziciriritse
Ibiraro by'ibyuma byoroheje n'amaduka yo gukoreramo
Amasambu n'inyubako z'agateganyo
Ibice bitari iby'ingenzi
Impamvu: Ni ibintu bihendutse kandi byoroshye kubikoresha, ariko bifite ubushobozi bwo kubitwara buciriritse.

ASTM A913
Ibikoresho binini byo mu kirere
Ibiraro birebire
Ibibuga by'imikino n'amazu y'ubucuruzi
Imishinga ikomeye y'inganda
Impamvu: Kugira imiterere y'umubiri woroshye no kumara igihe kirekire bishobora kugerwaho hakoreshejwe imbaraga nyinshi cyane.

Isoko n'ibyo Akarere gakunda

Imiterere y'icyuma ya ASTM A992: Iraboneka muri Leta Zunze Ubumwe za Amerika na Kanada, Uburasirazuba bwo Hagati, Aziya y'Amajyepfo y'Uburasirazuba ku nyubako.

Imiterere y'icyuma ya ASTM A572: Ikundwa cyane mu turere twa Amerika no mu turere tw’ibikorwa remezo nk’ibiraro n’inyubako nini.

Imiterere y'icyuma ya ASTM A283: Ikoreshwa cyane mu bikorwa bya gatatu mu kubaka bihendutse kandi byoroheje.

Imiterere y'icyuma ya ASTM A913: Ikoreshwa cyane cyane mu bihugu byateye imbere no mu mishinga minini nka Amerika, Uburayi, Uburasirazuba bwo Hagati, Aziya y'Iburasirazuba.

Ibipimo by'Ikiguzi n'Ubukungu

A283: Igiciro gito n'ubwiza buke

A992: Igiciro kiri hagati, imbaraga zihagije kandi byoroshye gukora

A572Ikiguzi giterwa n'icyiciro

A913: Igiciro kiri hejuru kuri buri kimwe, ariko imbaraga nyinshi zigabanya toni yose y'icyuma

Ibyuma bikomeye bishobora kugabanya ikiguzi cy’umushinga wose binyuze mu kugabanya ibikoresho, ubwikorezi n’ingano y’ibikoresho byo gushyiraho.

Gukora no gusudira

A283: Byoroshye gukata no gusudira

A992: Yakozwe kugira ngo ikoreshwe mu byuma bisudira

A572: Irasudira, ariko igenzura rikomeye rirakenewe kugira ngo ubone amanota meza

A913: Uburyo bushya butuma habaho ubushobozi bwiza bwo gusudira ku rwego rwo hejuru cyane.

Incamake n'igereranya

Igisanzwe Urwego rw'Imbaraga Ikoreshwa Risanzwe Urwego rw'Ikiguzi Amasoko Ashyushye
ASTM A992 Hejuru Inyubako, amakaramu Hagati Amerika, Uburasirazuba bwo Hagati, Aziya yo mu burasirazuba bw'Amajyepfo
ASTM A572 Hagati–Hejuru Ibiraro, ibimera Hagati–Hejuru Amerika, Uturere tw'ibikorwa remezo
ASTM A283 Hasi Inyubako z'urumuri Hasi Afurika, Aziya y'Epfo, Amerika yo Hagati
ASTM A913 Hejuru cyane Ibikoresho binini byo mu kirere, imishinga minini Hejuru Amerika, Uburayi, Uburasirazuba bwo Hagati, Aziya y'Iburasirazuba

ASTM A283, A992, A572 na A913 ni urwego rune rw'imikorere y'ibyuma by'ubwubatsi. A283 ni ukugira ngo ubukungu burusheho kuba bwiza, A992 ni inkingi y'ubwubatsi isanzwe, A572 itanga amahitamo menshi y'imbaraga ku bikorwa remezo naho A913 ni yo ifite agaciro gakomeye ku bikoresho biremereye kandi bigezweho. Imishinga y'ubwubatsi ikomeje kwiyongera irimo gutuma abantu benshi bimukira ku byuma by'ubwubatsi bikomeye ku isoko mpuzamahanga.
