C4 nitric acid resistant stainless steel
C4 (00Cr14Ni14Si4) is ultra-low carbon, high silicon austenitic stainless acid-resistant steel with excellent corrosion resistance in strongly oxidizing media.
Performance, far better than ordinary stainless steel (including 304L) compared with high ferrosilicon and high purity aluminum, its corrosion resistance is better than high purity aluminum and similar to high ferrosilicon. However, the mechanical strength and machining performance are unmatched by high purity aluminum and high ferrosilicon. Therefore, C4 steel is currently recognized as having strong oxidizing properties, especially Concentrated nitric acid is the material with the best comprehensive performance among media materials.

Applications of C4 nitric acid resistant stainless steel
1.C4 steel is very effective in pipes, valves, condensers, pumps, etc. used in indirect method (magnesium nitrate method) concentrated nitric acid equipment.
2.C4 steel material is: 00Cr14Ni14Si4 ultra-low carbon austenitic stainless steel, which has excellent resistance to intergranular and stress corrosion.
