Kev piav qhia
ER410NiMo yog cov hlau tsis xeb martensitic uas muaj cov tshuaj lom neeg muaj 11.0 - 12.5% Cr, 4.0 - 5.0% Ni, thiab 0.40 - 0.70% Mo. Nws tsim nyog rau kev vuam uas muaj roj tiv thaiv (xws li TIG / MIG) hauv txhua qhov chaw. Thaum lub sijhawm vuam, lub arc ruaj khov, thiab cov hlau tso tawm ua rau muaj kev tiv thaiv cavitation zoo heev, tiv thaiv xuab zeb hnav,
thiab cov khoom siv kho tshuab. Feem ntau tsis tas yuav tsum tau ua ntej vuam; kev kho cua sov tom qab vuam (PWHT) ntawm 580 ~ 620 ℃ rau 2 teev (ua raws li cua txias, AC) raug pom zoo raws li qhov yuav tsum tau ua. Cov hlau tso rau hauv yog tshuab tau thiab haum rau cov khoom siv siab.
Daim Ntawv Thov
Tsim los rau kev vuam ASTM CA6NM cov hlau cam khwb cia, 410/410S/405 stainless hlau, thiab cov hlau zoo sib xws 13% Cr – 4% Ni series. Cov ntawv thov ib txwm muaj xws li cov khoom siv siab (ua raws li cov qauv ntawm lub thawv siab), cov hniav turbine, cov li qub, cov kav dej siab, thiab cov khoom siv uas xav tau kev xeb thiab kev hnav tsis kam.

Cov Kev Ntsuas Vuam Pom Zoo
Cov pa roj tiv thaiv: Argon (Ar) lossis Ar + 1-2% O2 (rau TIG / MIG vuam, kho raws li cov txheej txheem tshwj xeeb).
Daim Ntawv Ceeb Toom
1. Xyuas kom tseeb tias qhov chaw ntawm cov hlau huv si thiab tsis muaj roj, xeb, lossis dej noo ua ntej siv kom tsis txhob cuam tshuam rau qhov zoo ntawm kev vuam.
2. Tswj cov roj kom huv thiab kom ntws kom txaus kom tiv thaiv tau qhov porosity thiab hydrogen-induced cracking.
