Eia kekahi mau mea koʻikoʻi no ka hoʻolauna ʻana i 440C stainless steel paʻa palahalaha:
1. Hoʻohui: 440C kuhiliʻole kila pāpaʻa pahu i haku muaʻia me ka chromium (16-18%), kalapona (0.95-1.20%), a me ka liʻiliʻi o nā mea e like me manganese, silicon, a me ka molybdenum.
2. Wear Resistance: 440C stainless steel flat bar is renowned for its outstanding wear resistance, e kūpono ana i nā noi e pili ana i nā mea abrasive, nā meaʻokiʻoki, nā bearings, a me nā mea pale pale.
3. Kū'ē Kū'ē: ʻOiai he kila kila kila kiʻekiʻe, hōʻike ka 440C i ke kūpaʻa maikaʻi.
4. Paʻa a me ka ikaika: 440C stainless steel flat bar he paʻakikī maikaʻi loa a me ka ikaika kiʻekiʻe, e hāʻawi ana i ka lōʻihi a me ka lōʻihi i nā noi noi.
