H68 tooj dag Description
Plasticity zoo heev: H68 muaj qhov zoo tshaj plaws plasticity ntawm commom tooj dag, nrog rau kev ua haujlwm txias thiab kub, ua rau nws tsim nyog rau kev sib sib zog nqus nqus, khoov, thiab lwm yam txheej txheem tsim.
High Strength and Ductility Balance: Tensile zog ranges dav (M Ntau dua lossis sib npaug li 290 MPa, mus txog 660 MPa9(Y)).
Corrosion Resistance: Zoo tiv taus rau dej tshiab thiab atmospheric corrosion. Txawm li cas los xij, nws muaj kev cuam tshuam rau kev ntxhov siab corrosion tawg hauv ammonia thiab seawater ib puag ncig (corrosion tus nqi kwv yees li 0.1 mm / a).
Kev Ua Haujlwm Ntau Yam: Txhawb nqa txias dov, kub dov, vuam, soldering thiab brazing, ua rau nws zoo tagnrho rau lub plhaub casings thiab precision Cheebtsam.

FAQ
Q: Qhov txawv ntawm H68 thiab H68A yog dab tsi?
A: H68A muaj cov kab mob arsenic (Raws li) txhawm rau txhim kho kev tiv thaiv corrosion thiab tiv thaiv dezincification, ua rau nws tsim nyog rau ib puag ncig hnyav.
Q: Puas yog H68 haum rau cov dej hiav txwv ib puag ncig?
A: Kev cuam tshuam ncaj qha ua rau muaj qhov corrosion kuj siab (0.1 mm / a). Kev tiv thaiv txheej los yog xaiv H68A raug pom zoo.
