2520 icuma kitagira ibara ni icuma kitagira ibara gikomeye-chromium-nickle austenitic ubushuhe-bushobora guhangana n'icuma kitagira ibara. Ivyo bimenyetso bihuye ni ibi bikurikira:
- Izina ry'igishinwa: Izina rya kera ryari 0Cr25Ni20, izina rishasha ni 06Cr25Ni20 (kode y'imibare y'igishinwa yunze ubumwe: S31008)
- Izina ry'Abanyamerika: 310S
- Ibindi bipimo mpuzamakungu: Ibipimo vy'i Buraya ni 1.4845, n'ibipimo vy'i Koreya ni STS310S
Ivyo bikoresho birangwa n’ivyuma vyinshi vyitwa chromium (24,00–26,00%) n’ivyuma vyinshi vyitwa nickel (19,00–22,00%), bifise carbone iri munsi canke ingana na 0,08%. Igaragaza ubushobozi bwiza cane bwo guhangana n’ivyuma, ubushobozi bwo guhangana n’ugusenyuka n’ubushobozi bwo guhangana n’ubushuhe bwinshi-. Ubushuhe bwayo bushobora gushika kuri degre 1150 , kandi ubushuhe bushobora gushika kuri degre 1200–1250 . Uburemere bwayo bw’umubiri ni nk’ibice 7,98–8,0 g/cm3, kandi imiterere yayo y’ubuhinga harimwo ubukomezi bwo gukomera Burengeye canke bungana na 520 MPa, ubukomezi bwo gutanga burengeye canke bungana na 205 MPa, n’uburebure Burengeye canke bungana na 4%.0.
2520 ivyuma bitagira ibara bikoreshwa cane mu guhingura amatiyo y’ifuru ashobora guhangana n’ubushuhe bwinshi, ibikoresho bihindura ubushuhe, imiyoboro y’amavuta, ibihimba vy’ubuhinga n’ibihimba vy’igisirikare, n’ibindi.
