CF8M Stainless Hlau Castings

CF8M yog qhov sib npaug ntawm wrought AISI 316 stainless hlau, txheem raws li ASTM A351 / A351M (Standard Specification for Castings, Austenitic, for Pressure-Containing Parts). Formulated nrog 18% chromium, 11% npib tsib xee, thiab 2.0-3.0% molybdenum, CF8M nthuav tawm kev ua haujlwm zoo tshaj plaws rau pitting, crevice corrosion, thiab chloride-induced stress corrosion cracking piv rau non-molybdenum qib zoo li CF8 (valente).
Jining Wabon Precision Hlau Co., Ltd. manufactures kev cai CF8M peev castings siv 100% silica sol txheej txheem tooling. Los ntawm kev siv silica sol slurry es tsis yog dej iav binders, peb tshem tawm qhov chaw pitting thiab tswj cov kab ntev ntev nyob rau hauv ISO 8062-3 CT4 rau CT6, tsim cov khoom siv nruj rau corrosive fluid tuav, marine propulsion, chemical processing, thiab khoom noj khoom haus.
