Industrial S17400 precipitation hardening seamless steel pipe

S17400 is a martensitic precipitation hardening stainless steel, also known as 17-4PH. This material is mainly composed of elements such as iron, chromium, nickel, titanium, and copper, and has high strength, high hardness, excellent welding performance, and corrosion resistance. The alloy composition of S17400 makes it excellent in mechanical properties, corrosion resistance, and processability, especially suitable for various industrial fields that require high strength, corrosion resistance, wear resistance, and fatigue resistance. Its applications are very extensive, including but not limited to manufacturing bearings, pump shafts, valves, mechanical seals, aircraft engine components, rocket engine components, ship components, etc. In addition, S17400 is widely used in the field of medical engineering, such as artificial skeletons, dental braces, pacemakers, etc.

Seamless pipe is a long steel strip with a hollow cross-section and no seams around it.

The characteristics of stainless steel seamless pipes:

Firstly, the thicker the wall thickness of the product, the more economical and practical it is. The thinner the wall thickness, the higher its processing cost will be;

Secondly, the process of this product determines its limited performance. Generally, seamless steel pipes have low accuracy, such as uneven wall thickness, low surface brightness inside and outside the pipe, high sizing cost, and difficult removal of pitting and black spots on the inner and outer surfaces;

Thirdly, its detection and shaping must be processed offline. Therefore, it demonstrates its superiority in high pressure, high strength, and mechanical structural materials.
