Roostevabast terasest keevitatud toru on torutüüp, mis on valmistatud roostevabast terasest ja mis on õmbluse juures kokku keevitatud. Seda kasutatakse tavaliselt rakendustes, kus on vaja suurt tugevust, vastupidavust ja korrosioonikindlust, näiteks surveanumate, soojusvahetite ja torustike ehitamisel. Roostevabast terasest keevitatud torude tootmisprotsess hõlmab esmalt roostevabast terasest lameda riba vormimist torukujuliseks. Seejärel kuumutatakse riba servad kõrgele temperatuurile ja sulatatakse kokku elektrivoolu või suure energiaga kiire abil. See protsess loob tugeva ja pideva õmbluse kogu toru pikkuses.
Roostevabast terasest keevitatud toru on saadaval erinevates suurustes, seinapaksustes ja roostevabast terasest klassides, sealhulgas austeniitse, feriitse ja dupleksterase klassides. Klassi ja seinapaksuse valik sõltub konkreetsest rakendusest ja toru nõutavatest mehaanilistest omadustest.
