440—Ithuluzi lensimbi lokusika eliphakeme elinokuqukethwe okungaphezulu kwekhabhoni. Ngemuva kokwelashwa okufanele kokushisa, amandla aphezulu wesivuno angatholakala. Ubulukhuni bungafinyelela ku-58HRC, okungenye yezinsimbi ezinzima kakhulu ezingenasici. Isibonelo esivame kakhulu sohlelo lokusebenza yi- “razor blades”. Kunamamodeli amathathu asetshenziswa kakhulu: 440A, 440B, 440C, no-440F (kululauhlobo lokucubungula).
Isimiso sensimbi engagqwali ibhola:
Amabhola ensimbi angenazinsimbi awafakazeli ukugqwala, kepha akulula ukugqwala. Umgomo ngukuthi ngokungezwa kwe-chromium, kwakheka ungqimba oluminyene lwe-chromium oxide ebusweni bensimbi, olungavimba ngempumelelo ukuxhumana kabusha phakathi kwensimbi nomoya, ukuze umoya-mpilo osemoyeni ungangeni ensimbi ibhola, ngaleyo ndlela kuvimbela Umphumela wensimbi amabhola ukugqwala.
I-China National Standards (CNS), i-Japanese Industrial Standards (i-jis) ne-American Iron and Steel Institute (AISI) zisebenzisa amadijithi amathathu ukukhombisa izinsimbi ezahlukahlukene ezingenazinsimbi, ezicashunwa kabanzi embonini, lapho uchungechunge lwama-200 luyi-chromium-nickel-manganese -based austenitic Stainless steel, 300 series is chromium-nickel austenitic stainless steel, 400 series chromium stainless steel (eyaziwa ngokuthi insimbi engagqwali), including martensite and ferrite.
