Kev piav qhia

E410NiMo-15 yog ib lub hlau stainless hlau martensitic uas muaj cov txheej txheem sodium hydrogen tsawg, muaj 11.0-12.5% Cr, 4.0-5.0% Ni, thiab 0.40-0.70% Mo. Nws tsim nyog rau txhua qhov chaw vuam hlau arc (SMAW) nrog arc ruaj khov, tsawg spatter, thiab zoo heev slag detachability. Cov hlau tso muaj lub zog siab, zoo corrosion tsis kam, thiab tawg tsis kam. Preheating yog pom zoo rau cov workpieces tuab, thiab post-weld cua sov kho (PWHT) ntawm 580 ~ 620 ℃ (1-2 teev, cua txias, AC) yog qhov yuav tsum tau ua.

Daim Ntawv Thov

Zoo tagnrho rau kev vuam ASTM CA6NM cam khwb cia hlau, 13% Cr-4% Ni series hlau (piv txwv li, Cr13Ni4Mo, Cr13Ni5Mo), thiab cov hlau tsis xeb martensitic zoo sib xws. Cov ntawv thov ib txwm muaj xws li kev kho vuam ntawm cov hydropower turbine runners, lub cev valve, cov kav dej siab, thiab kev ua kom cov khoom siv cavitation hnav. Kuj tseem siv rau kev kho cov khoom siv tawv tawv xws li cov crusher rolls thiab cov twj tso kua mis casings.
