High-strength hasi -ane icuma (HSLA) ni ubwoko bw’icuma c’ivyuma bitanga ubushobozi bwiza canke ubushobozi bwinshi bwo gusenyuka kuruta icuma ca carbone. Ivyuma vya HSLA biratandukanye n’ibindi vyuma kuko bitakozwe kugira ngo bishike ku kintu kinaka c’imiti, ahubwo ko hariho ibintu vy’ubuhinga. Bafise umuyagankuba uri hagati ya 0,05 na 0,25% kugira ngo bashobore kuguma bafise ubushobozi bwo gukora neza. Ibindi bihimba vy’umubiri birimwo 2,0% vy’ivyuma vy’umuringa n’ivy’umuringa bitobito, nickel, niobium, azote, vanium, chromium, titanium, calcium, - ibintu bidasanzwe, canke zirconium. Umuringa, titanium, vanium n’ivy’amazi ni vyo vyongerwako kugira ngo bikomeze. Ivyo bintu bigamije guhindura imiterere y’ivyuma vy’ivyuma vy’umuyagankuba, akenshi bikaba ari ifumbire - Impumuro, kugira ngo ikoreshe neza cane ibihimba vy’umubiri vy’ivyuma vy’ibara ry’agahama. Ivyo bikuraho ubukomezi- Ingaruka z’igice c’uburemere bw’ipereza ariko bukaguma bukomeza kandi bugatuma inkomezi z’ikintu zirushirizaho mu gutunganya ubunini bw’intete, iyo mu gihe c’ifumbire yongera inkomezi z’umwimbu n’ibice 50% ku guhagarika igipimo c’intete. Gukomeza imvura biragira uruhara rutoyi, na vyo nyene. Inkomezi z’umwimbu zazo zishobora kuba hagati y’ibice 250–590 vy’ama megapascal (36.000–86, pepsi). Kubera inkomezi zavyo nyinshi n’ubukomezi za HSLA akenshi bisaba ububasha 25 gushika kuri 30% kugira ngo bube, ugereranije n’ivyuma vy’umuyagankuba.
Umuringa, silikoni, nickel, chromium, na phosphore vyongerwako kugira ngo bishobore kwongereza ubushobozi bwo gusenyuka. Zirconium, calcium, na state - ibintu vyongeweko ku sulfide- igenzura ry'imiterere y'umubiri ryongera ubushobozi bwo gukora. Ivyo birakenewe kubera ko ivyuma vyinshi vya HSLA bifise ubushobozi bwo gukora. Inkomezi z’ubushobozi n’ingaruka zishobora guhinduka cane iyo zigeragejwe mu buryo burambuye no mu buryo bunyuranye n’intete. Bends zihuye n’intete y’igihe kirekire cane zirashobora guca ku ruhande rw’inyuma kubera ko zishikirwa n’imitwaro y’ibintu vyinshi. Ivyo bimenyetso vy’inzira biragabanywa cane mu vyuma vya HSLA vyavuwe kugira ngo bigenzure igiti c’umuberoshi.
Bikoreshwa mu modoka, ibikamyo, ibiraro, ibiraro, ibiraro vy’ibizingiti n’ibindi bikoresho bigenewe gutwara imibabaro myinshi canke bikeneye inkomezi nziza-ba - igipimo c’uburemere. Umusaraba w’icuma HSLA - Ivyuma n’imiterere akenshi biba 20 gushika kuri 30% kuruta icuma ca carbone gifise inkomezi imwe.
Ivyuma vya HSLA na vyo nyene birashobora guhangana n’umugese kuruta ivyuma vyinshi vy’ivyuma vy’umuyagankuba kubera ko ata perilite – ivyuma vyiza vy’ivyuma vy’ibara ry’agahama (hafi y’ivyuma vyiza cane) n’ivyuma vy’ibara ry’agahama.[5] Ivyuma vya HSLA akenshi bifise uburemere bw’ibiro 7800/m3.
Turafise ubushobozi bwinshi bwo gutunganya ibintu n’ubuhinga bwo gukora, ububiko bw’ububiko n’ubuhinga bugoranye, n’iherezo-ba-ba ibiharuro vy’ibiharuro n’imirongo y’ugutanga.Isosiyete ishobora kuba umufatanyabikorwa wawe kugira ngo ihure n’ivyo ishirahamwe ryawe rikeneye no gutanga urutonde rw’ibikorwa vyose ku mukiriya wese. Turashima uburyo bwacu bwo kugisha inama .
Imisoro ishushe: hasi-aloy n'isonga - isahani y'ingoma, Ubushinwa buri hasi-ara hejuru na - abahinguzi b'ibipande vy'ivyuma, abagurisha, uruganda
