Cold-Rolled 304 Stainless Steel Superheater Tube
Seamless cold-rolled tube of 304 stainless steel, 12.7 mm OD, engineered for superheater sections in power plant boilers to handle superheated steam. The material's oxidation resistance at high temperatures qualifies it for this critical application. Falls under 7304.41.30.15 for its seamless, cold-formed nature, circular cross-section under 19 mm, and superheater suitability.
