1.4541 stainless steel cold-rolled pipes are annealed at approximately 1605°F (740°C) and then water-quenched to improve corrosion resistance. They can be used in a temperature range of 538°C to 870°C. These pipes are ideal for applications such as high-pressure fluid transportation, structural support, expansion joints, heat exchangers, furnace components, aircraft exhaust manifolds, and bellows.
