Stainless steel has higher resistance to oxidation (rust) and corrosion in several environments.

The first hot cracking is called segregation crack, because the liquid film formation and solidification process of segregation of alloying elements

Welded 304 Stainless Steel tubing is less costly than seamless or welded-and-drawn tubing, and requires less stock removal in machining applications.
