Stainless Steel DIN 1.4878 Seamless Pipes
1.4878 SS Seamless Pipe is a stainless steel containing 14% to 15.5% chromium, 3.5% to 5.5% nickel, and 2.5% to 4.5% copper. It has good strength and toughness and excellent corrosion resistance after heat treatment. Commonly used in manufacturing aerospace equipment, nuclear reactor equipment, etc.
Plating treatment is to improve the surface condition and corrosion resistance of 1.4878 SS Hollow Pipe by plating a layer of protective coating on the surface, such as chromium plating, nickel plating, etc. Surface active elements refer to some elements added by SS Round Pipe in 1.4878, such as sulfur, potassium, sodium and carbon.
The chemical composition of 1.4878 SS Thin Wall Pipe is: Chromium (Cr): 12.0-14.0%, Carbon (C): 0.15-0.33%, Silicon (Si): ≤1.0%, Manganese (Mn): ≤1.0%, Phosphorus ( P): ≤0.06%, sulfur (S): 0.15-0.35%, copper (Cu): 0.6-1.2%. 1. The physical properties of 4878 stainless steel pipe refer to the physical performance of the material, including density, thermal expansion coefficient, thermal conductivity, resistivity, magnetism, elastic modulus, heat capacity and other parameters.
