Simbi isina tsvina 409

409 Stainless simbi iFerritic simbi inopa yakanaka michina zvivakwa uye yakakwirira-tembiricha corrosion resistance. Inowanzo onekwa sechromium simbi isina tsvina, ine maapplication ari exhaust masisitimu emota uye maapplication anoda weldability.

409 masimbi anowanikwawo mumhando dzakadzikama zvakanyanya, senge mamakisi S40930, S40920 uye S40910. Kugadzikana kwemagiredhi aya kunopiwa nekuvapo kweniobium, titanium, kana zvese zviri zviviri, mukuumbwa kwesimbi.

Possible Alternative Grades

Giredhi	Properties
3CR12	Nyore kupinza uye yakanaka corrosion resistance. Zvikamu zvinorema zviri nyore kuwanikwa kana zvichienzaniswa ne409.
304	High heat resistance uye corrosion resistance. Grade 304 inodhura.
321	Zvirinani kupisa kupisa kana uchienzaniswa ne304 kana 409.
Aluminium simbi	Yakachipa kupfuura giredhi 409 simbi isina tsvina, asi isingadzivirirwe nekupedza gasi.
