Imiyoboro irashobora kugabanywamo imiyoboro yicyuma nu miyoboro idafite ibyuma. Imiyoboro yicyuma irigabanywa mubwoko bwa ferrous na ferrous. Ibyuma bya fer bigizwe ahanini nicyuma, mugihe ibyuma bitagira fer bitagizwe nicyuma. ni imiyoboro idafite ferrous.Imiyoboro ya plastike, imiyoboro ya beto, imiyoboro itondekanye ya pulasitike, imiyoboro itondekanya ibirahure, imiyoboro itondekanye na beto hamwe n'indi miyoboro idasanzwe ishobora gukoreshwa mu buryo bwihariye yitwa imiyoboro idafite ibyuma. Imiyoboro y'icyuma ni imiyoboro ikoreshwa cyane mu nganda z’ingufu;imiyoboro ya karubone ikoreshwa cyane.Ibipimo bya ASTM na ASME bigenga imiyoboro itandukanye hamwe nibikoresho bikoreshwa mu nganda zitunganya.
Ibyuma bya karubone nicyuma gikoreshwa cyane munganda, bingana na 90% byumusaruro wibyuma byose. Ukurikije ibirimo karubone, ibyuma bya karubone bigabanyijemo ibyiciro bitatu:
Mu byuma bivanze, ibipimo bitandukanye byibintu bivangwa bikoreshwa kugirango ugere kubintu byifuzwa (byanonosowe) nko gusudira, guhindagurika, gukora imashini, imbaraga, gukomera no kurwanya ruswa, nibindi. Bimwe mubintu bikunda gukoreshwa cyane hamwe ninshingano zabo nibi bikurikira:
Icyuma kitagira umwanda nicyuma kivanze kirimo chromium ingana na 10.5% (ntarengwa) .Icyuma kitagira umwanda kigaragaza imbaraga zidasanzwe zo kwangirika bitewe no gushiraho urwego ruto cyane rwa Cr2O3 hejuru. Uru rwego ruzwi kandi nk'urwego rwa pasiporo. Kongera ubwinshi bwa chromium bizarushaho kunoza ruswa yo kwangirika kw'ibikoresho. silicon na manganese.Icyuma kitagira umwanda cyongeye gushyirwa mubikorwa nka:
Usibye amanota yavuzwe haruguru, amanota amwe yateye imbere (cyangwa amanota yihariye) ibyuma bitagira umwanda nabyo bikoreshwa mu nganda ni:
Ibyuma by'ibikoresho bifite karubone nyinshi (0.5% kugeza 1.5%). Ibirimo byinshi bya karubone bitanga ubukana n'imbaraga nyinshi.Iki cyuma gikoreshwa cyane cyane mugukora ibikoresho no kubumba.Icyuma cyibikoresho birimo tungsten, cobalt, molybdenum, na vanadium kugirango byongere ubushyuhe bwicyuma no kwambara birwanya ndetse no kuramba.Ibi bituma ibyuma bikoreshwa muburyo bwo gukata no gucukura.
Iyi miyoboro ikoreshwa cyane mubikorwa bitunganyirizwa.Ibisobanuro bya ASM na ASME kumiyoboro isa itandukanye, ariko amanota yibikoresho ni amwe.Eg:
Ibikoresho hamwe nibintu biri kuri code ya ASME na ASTM birasa usibye izina.Imbaraga zingutu za ASTM A 106 Gr A ni 330 Mpa, ASTM A 106 Gr B ni 415 Mpa, na ASTM A 106 Gr C ni 485 Mpa. Umuyoboro wibyuma bikoreshwa cyane ni ASTM A 106 Gr B.Hari uburyo bwa ASTM A 106 Gr nicyiciro gikoreshwa cyane mubyuma bya karubone kumuyoboro.ASTM Umuyoboro wa 53 uraboneka mubyiciro bibiri:
ASTM A 53 Umuyoboro ugabanijwemo ubwoko butatu - Ubwoko E (ERW - Resistance Welded), Ubwoko F (Furnace na Butt Welded), Ubwoko S (Seamless) .Mu bwoko bwa E, ASTM A 53 Gr A na ASTM A 53 Gr B irahari.Mu bwoko bwa F, ASTM A 53 Gr A iraboneka, naho mubwoko bwa 53, ASTM A 53 Gr A 53 Gr Umuyoboro usa na ASTM A 106 Gr A kuri 330 Mpa.Imbaraga zingana za ASTM A 53 Gr B umuyoboro usa na ASTM A 106 Gr B kuri 415 Mpa.Ibi bikubiyemo imiyoboro yo mucyuma cya karubone ikoreshwa cyane mubikorwa byo gutunganya.
Imiyoboro ikoreshwa cyane munganda zitunganya ibyuma byitwa austenitis ibyuma bitagira ibyuma.Icyingenzi cyingenzi kiranga ibyuma bitagira ibyuma bya austenitike ni uko atari magnetiki cyangwa paramagnetic. Ibintu bitatu byingenzi byerekana ibyuma bitagira umuyonga ni:
Hano hari amanota 18 muribi bisobanuro, muri byo 304 L niyo ikoreshwa cyane.Icyiciro kizwi cyane ni 316 L kubera ko irwanya ruswa nyinshi.ASTM A 312 (ASME SA 312) ku miyoboro ya santimetero 8 cyangwa munsi ya diametre.
Ibi bisobanuro bireba imiyoboro minini ya diameter yasuditswe. Gahunda yo kuvoma ivugwa muriki gisobanuro ni Gahunda ya 5S na Gahunda ya 10.
Weldability of Austenitic Stainless Steel - Ibyuma bya Austenitike bitagira ibyuma bifite ubwiyongere bukabije bwumuriro kuruta ibyuma bya ferritic cyangwa martensitike bitagira umuyonga.Kubera koeffisente yo hejuru yo kwagura amashyanyarazi hamwe nubushyuhe buke bwumuriro wibyuma bya austenitike, ibyuma byahinduwe cyangwa ibikoresho byintambara bishobora kubaho mugihe cyo gusudira. ing inzira.Gusudira arc gusudira (SAW) ntibisabwa mugihe ibyuma bisabwa byuzuye bya austenitike cyangwa ibyuma bya ferrite byo hasi bisabwa. Imbonerahamwe (Umugereka-1) nubuyobozi bwo guhitamo insinga zuzuza cyangwa electrode ikurikije ibikoresho fatizo (kumashanyarazi ya austenitike).
Chromium molybdenum tubing ikwiranye numurongo wa serivise yubushyuhe bwo hejuru kuko imbaraga zingana za chrome molybdenum tubing ntigihinduka mugihe cy'ubushyuhe bwinshi. Umuyoboro usanga ikoreshwa mumashanyarazi, guhanahana ubushyuhe, nibindi nkibyo. Umuyoboro ni ASTM A 335 mubyiciro byinshi:
Imiyoboro y'icyuma ikoreshwa mu kuzimya umuriro, gutemba, umwanda, imirimo iremereye (ku nshingano ziremereye) - amazi yo mu kuzimu n'ibindi bikorwa.Icyiciro cy'imiyoboro y'icyuma ni:
Imiyoboro y'icyuma ikoreshwa mu miyoboro yo munsi y'ubutaka muri serivisi zishinzwe kuzimya umuriro. Imiyoboro ya Durr iragoye kubera ko hari silikoni. Iyi miyoboro ikoreshwa muri serivisi ya acide y'ubucuruzi, kuko urwego rugaragaza ko irwanya aside y'ubucuruzi, ndetse no gutunganya amazi asohora imyanda ya aside.
