Tsawg-sodium hydrogen tshuaj txheej Cr-Ni-Si-Mo valve surfacing electrode;
Surfacing hlau yog ib qho me me ntawm ferrite austenite qauv, muaj qhov kub thiab txias tsis kam, yaig tsis kam thiab lwm yam khoom, siab kub hardness, zoo thermal stability thiab thermal qaug zog tsis kam.
Nrog rau qhov nce ntawm lub sij hawm laus, lub hardness thiab abrasion kuj ntawm surfacing hlau yog ntxiv txhim kho.
Ningbo Chengwei Hlau Khoom Co., Ltd. yog lub tuam txhab kev lag luam thoob ntiaj teb nrog kev tshawb fawb thiab kev tsim kho, kev tsim khoom, muag thiab kev tswj hwm. Nws tau tsim nyob rau hauv 2020.
