The crystal structure of SS UNS S30409 makes it non-magnetic and less brittle at lower temperatures. Moreover for the addition of higher hardness and strength, carbon is mixed up in this. Additional chemical, mechanical or physical properties need to be considered in case of TP304H SS Welded Pipe in order to achieve the overall service performance requirements. This ASTM A312 TP 304H SS also comes under the category of marine grade steel because of its ability to resist saltwater corrosion.
