AISI 321 vlekvrye staal (SS321) is basies tipe 304 met die byvoeging van titanium (Ti), wat karbiede teen sensitisering stabiliseer om interkorrelpresipitasie van chroomkarbied te voorkom wanneer die staal verhit word tot 'n temperatuur binne die sensitiseringsbereik (soos tydens sweiswerk) . 321H is om die beste kruipsterkte en kruipbreuksterkte te verkry. TP321 vlekvrye staal is vir naatlose, gelaste en swaar koud gewerkte pype.
