Sandvik Sanicro 38/4L7 is a composite tube consisting of Sanicro 38, a corrosion-resistant nickel-base alloy on the outside diameter, and carbon steel (A210 GrA-1) for water-wetted service on the inside. The design is placed entirely on the inside tube; however, there is a contribution from both. This datasheet provides information on composition and physical properties. It also includes information on forming, heat treating, and joining. Filing Code: SA-483. Producer or source: Sandvik.
