420J1 420J2 rīpene maitai kore waikura
Whakaahuatanga Poto:
Ko ngā rīpene maitai kore waikura 420J1 me 420J2 he momo rauemi maitai kore waikura noa e rua nō te raupapa maitai kore waikura martensitic. He rerekētanga kei roto i te hanganga matū me ngā āhuatanga. Anei tētahi tirohanga poto mō ia mea:
1. Ripanga maitai kore waikura 420J1: He maitai kore waikura waro-iti te 420J1, he tino pakeke, he tino kaha hoki. Ko tōna hanganga matū he tata ki te 0.16-0.25% te waro, tata ki te 1% te chromium, me te iti o te molybdenum. He pai te ātete o te 420J1 ki te waikura, ki te tapahi, me ngā āhuatanga huri. He mea whakamahi noa mō te hanga maripi, ngā taputapu pokanga, ngā wāhanga miihini, me ētahi mahi ātete-kakahu.
2. Ripanga maitai kore waikura 420J2: He maitai kore waikura waro-waenga te 420J2, he tino pakeke, he ātete hoki ki te pakaru. Ko tōna hanganga matū he tata ki te 0.26-0.35% te waro me te tata ki te 1% te chromium. He nui ake te ihirangi waro o te 420J2 i te 420J1, ā, ka nui ake te pakeke me te mahi tapahi. He maha ngā whakamahinga mō te hanga maripi, mata, taputapu pokanga, puna, me ētahi wāhanga miihini.
