Womic Steel – Ngā Otinga Paipa Kowiri tira 347H Mahi-Teitei

1. Tirohanga Whānui o ngā Rauemi

Ko te paipa kowiri tira 347H he kowiri tira austenitic waro-teitei kua whakapūmauhia e te niobium, e mōhiotia ana mō tōna kaha pāmahana teitei, tōna āheinga whakarewa pai, me tōna ātete tino pai ki te waikura intergranular. Mā te tāpiri o te niobium (Nb) ka whakapai ake i te kaha ngoki me te aukati i te maturuturunga o te chromium carbide i ngā rohe o te kōhao, ka whakarite kia pai ake te ātete ki te aro.

2.Te Hanganga Matū (Noa)

3. Ngā Āhuatanga Mīhini me te Waikura

3. Tuhi Matao: Tuhi matao maha-haere mō te rahi tika me te whakaotinga mata

4. Maimoatanga Wera: Te whakamahana i te otinga i te 980–1150°C, te tinei tere i te wai hei pehi i te maturuturunga o te warowaihā

5. Whakarewa: Ngā tukanga GTAW (TIG), PAW, me SAW, mā te whakamahi i te waea whakakī ER347 hei whakau; kei te wātea ngā kōwhiringa whakakore i muri

6. Whakaotinga Mata: Te whakapūkara, te whakakorekore (HNO₃/HF), me te whakakanapa ā-ringa (Ra ≤ 0.2µm mēnā ka tonoa)

7. Tirotiro: 100% RT (whakamātautau irahiko) mō ngā whakarewa; whakamātautau irahiko, waikura, PMI, whakamātautau waikura ā-whatu e hiahiatia ana
