420 SS(Stainless Steel) siliga buufinta kulaylka waa shay tayo sare leh oo loogu talagalay codsiyada buufinta arc. Waxaa lagu yaqaan caabbinta daxalka aad u wanaagsan, engegnaanta sare, iyo iska caabbinta xirashada wanaagsan, 420 SS waa bir aan lahayn martensitic oo bixisa ilaalinta dusha sare ee adag. Siligan waxaa si caadi ah looga isticmaalaa warshadaha sida petrochemical, koronto, baabuurta, iyo badda si kor loogu qaado cimri dhererka iyo cimriga qaybaha muhiimka ah. Xadhkaha buufinta kulaylka ee 420 SS wuxuu ku habboon yahay codsiyada u baahan dahaar adag oo xidhan oo adkaysi u leh oo leh iska caabin daxaleed dhexdhexaad ah.
Diyaarinta saxda ah ee dusha sare waxay muhiim u tahay in lagu gaaro natiijooyin wanaagsan iyadoo la adeegsanayo 420 SS silig buufinta kuleylka ah. Dusha la dahaarinayo waa in si taxadar leh loo nadiifiyaa si looga saaro wasakhda sida dufanka, saliidda, wasakhda, iyo oksaydhyada. Ku qarxinta birta leh aluminium oxide ama silikoon carbide ayaa lagula talinayaa si loo gaaro qallafsanaanta dusha sare ee 50-75 microns. Dusha nadiifka ah ee qallafsan waxay kor u qaadaysaa ku-xidhka dahaarka buufinta kulaylka, taasoo horseedaysa hagaajinta waxqabadka iyo cimri dhererka.
