Ngā Rakau Whakarewa Kowiri tira AWS A5.4 E316L-16
AWS: SFA 5.4 E316L-16
IS: 5206 E19.12.2.LR16
WAEHERE ISO EN: 3581-AE 19 12 3 LR 3 2
Ngā Āhuatanga o te Whakamahinga:
He momo hiko raima-titania te E316L-16, he pai te whakamahinga me te ngāwari ki te whakarewa.
I te mea he hanganga austenite tō te konganuku whakarewa-katoa kei roto te nui tika o te ferrite, he pai te ātete ki te pakaru. He tino pai tōna ātete ki te waikura intercrystalline i te āhua kua whakarewahia nā te mea he iti ake te ihirangi waro, ā, he pai ake te ātete ki te waikura intergranular i tērā o te E316L-16, ā, kei roto hoki te Mo. He pai hoki te ātete ki te wera.
He tino ātete te E316L-16 ki te makuku, ā, he pai hoki te ātete ki te pūngao.

Te Whakatūpato：
1. Whakamahia he pewa poto me te poroporo aho hei aukati i te urunga mai o te wera.
2. Kia maroke ngā irahiko. Whakamaroketia anō ngā irahiko i te 250-300°C mō te haora kotahi.
Ngā Tuhipoka mō te Whakamahinga:
Me rua me te hawhe te whānui o te raranga i te whānui o te hiko.
Tangohia ngā paru pērā i te hinu me te puehu i te awaawa.
Whakamarokehia ngā irahiko i te 350 (662) mō te 60 meneti i mua i te whakamahinga.
