420 SS (Stains aan sal lahayn) sicirka ku buufinta kuleylka waa shey tayo sare leh oo loogu talagalay in lagu buufiyo codsiyada buufin ee arc. Waxaa lagu yaqaanaa iska caabintiisa aadka u fiican, adkeyn, iyo caabbinta wanaagsan, 420 ss waa bir bir aan caadi ahayn oo bixiya badbaadin dusha sare ah. Wire siliggan waxaa badanaa loo isticmaalaa warshadaha sida petrochemical, jiilka awooda, gawaarida, iyo badda si kor loogu qaado cimri dhererka iyo nolosha muhiimka ah. Xirmooyinka buufinta kuleylka ee 420 ss ss-ka ayaa ku habboon codsiyada u baahan daaqad adag, oo jilicsan oo leh iska caabin hufan oo dhexdhexaad ah.
Diyaarinta dusha saxda ah ayaa muhiim u ah gaarista natiijooyinka ugu fiicneyd ee leh 420 ss vererl spay silig. Dusha sare in lagu dahaadey waa in lagu daboolaa waa in si toos ah loo nadiifiyaa si looga saaro wasakhoolka sida dulucda, saliida, wasakhda, iyo digaagga. Qarax aad u qafiif ah oo leh aluminium oxide ama silicon Carbide ayaa lagula talinayaa in lagu gaaro dusha sare ee 50-75 micron. Dusha sare ee nadiifka ah ee looxyada ayaa kor u qaadaya kudhaca dareenka kuleylka kuleylka, taasoo horseedaysa in la wanaajiyo waxqabadka iyo cimri dhererka.
