Hauv kev phais, qhov zoo thiab kev ntseeg siab ntawm kev phais thiab cov khoom siv yog qhov tseem ceeb. Ib qho ntawm cov khoom tseem ceeb ntawm kev phais phais yog rab koob phais, uas feem ntau yog ua los ntawm cov khoom siv kho mob xws li Alloy 455 thiab Alloy 470. Cov alloys tshwj xeeb yog tsim los tsim kom muaj lub zog tsim nyog, toughness thiab nruj uas yuav tsum tau siv rau cov koob phais.
Alloy 455 yog ib lub hnub nyoog martensitic-hardening stainless hlau uas tuaj yeem tsim nyob rau hauv ib lub xeev kuj mos. Lub zog tensile siab, zoo toughness thiab nruj tuaj yeem tau los ntawm kev kho cua sov yooj yim. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau rab koob phais vim nws tuaj yeem tiv taus qhov kev ntxhov siab thiab lub zog uas tau ntsib thaum phais. Tsis tas li ntawd, Alloy 455 tuaj yeem siv rau hauv qhov mob annealed thiab weldable raws li nag lossis daus-hardened stainless hlau, ua rau nws muaj ntau yam thiab yooj yim rau tshuab.
Alloy 470, ntawm qhov tod tes, kuj yog ib qho tshwj xeeb kho martensitic stainless hlau uas muab ib rab koob nyuaj. Qhov no yog qhov tseem ceeb rau cov koob phais vim nws tso cai rau kev nkag mus zoo dua thiab ua haujlwm zoo thaum lub sijhawm suturing. Kev ua haujlwm hardening tus nqi ntawm 470 alloy yog me me, thiab ntau yam txheej txheem txias txias tuaj yeem siv los tsim cov koob raws li qhov xav tau ntawm kev ua haujlwm phais sib txawv.
Kev siv cov khoom siv kho mob no ua kom cov koob phais muaj zog, ruaj khov thiab txhim khu kev qha, txo qhov kev pheej hmoo ntawm kev tawg thaum phais. Tsis tas li ntawd, lub zog tensile siab ntawm cov alloys muab cov koob phais nrog qhov tsim nyog sharpness kom ua tiav qhov tseeb thiab zoo suturing.
Nyob rau hauv luv luv, daim ntawv thov ntawm kev kho mob alloys xws li Alloy 455 thiab Alloy 470 nyob rau hauv phais sutures thiab koob plays lub luag hauj lwm tseem ceeb hauv kev ua kom muaj kev vam meej thiab kev nyab xeeb ntawm kev phais. Cov alloys no muab lub zog, toughness thiab durability xav tau rau cov koob phais, ua rau lawv yog ib feem tseem ceeb ntawm kev kho mob.
