Stainless Steels Classifications Stainless steels are commonly grouped into martensitic stainless steels, ferritic stainless steels, austenitic stainless steels, duplex (ferritic-austenitic) stainless steels, and precipitation-hardening stainless steels Stainless steels are in general grouped into martensitic stainless steels ferritic stainless steels austenitic stainless steels duplex (ferritic-austenitic) stainless steels precipitation-hardening stainless steels Alloying metallic elements added during the…
Piping Design Videos 06: Fired Heaters and Boilers The following list of Fired Heaters and Boilers Videos, I think would be helpful not only for Trainee Piping Designers and Engineers, but also as a refresher or reference for experienced Pipers. Please note some of the videos are Visual only, that is, without any Audio. Be aware that in the…
