317L (00Cr19Ni13Mo3, UNS S31726) alloy is an austenitic stainless steel based on molybdenum. It has stronger resistance to chemical corrosion compared to conventional chromium nickel austenitic stainless steel such as 304 alloy. In addition, compared to conventional stainless steel, 317L alloy has higher ductility, stress corrosion resistance, compressive strength, and high-temperature resistance. It is low carbon grade or L grade, which has anti Sensitization performance during welding and heat treatment.
317L steel has good seawater and SCC resistance compared to 316L, and is used in chemical ships, chemical products, Reactors, and other chemical equipment that require high corrosion resistance
SUS317L Chemical composition: carbon (C) ≤ 0.030, manganese (Mn) ≤ 2.00, nickel (Ni) 11.0-15.0, silicon (Si) ≤ 1.00, phosphorus (P) ≤ 0.045, sulfur (S) ≤ 0.030, chromium (Cr) 18.0-20.0, molybdenum (Mo) 3.0-4.0
317L stainless steel ball valve:
The 3171 stainless steel ball valve produced by our company can be mainly divided into two types based on the different opening of the ball core: type 0 and type V. The Type 0 adopts a floating principle design, and the main components of the valve are cast through composite casting. The valve seat inspection cover is made of polytetrafluoroethylene. The overall valve body cavity has no shrinkage, zero leakage, low positive force, large flow rate, small torque, labor-saving switch, simple structure, and convenient maintenance and disassembly in the later stage. Type stainless steel ball valves mostly use fixed valves, with a V-shaped port on the ball core, which plays a role in shear flow characteristics of individual materials, making this valve widely used in high viscosity, small particles or fiber rich working conditions, with good adjustability. Therefore, according to different working conditions, we can choose different ball valves for you. For those who want to have the function of regulating the pipeline, they can choose V-type ball valves. For those who only have a cut-off function, they can choose 0-type ball valves.
Introduction to 317L stainless steel: The relevant grades of 317L stainless steel include 22r19Ni13M03 and SUS37L. It has good welding performance, corrosion resistance, and welding performance. The addition of platinum brings high temperature resistance, with small grains and large grain boundaries, and deformation mostly occurring at grain boundaries. Therefore, it has good resistance to grain growth and can maintain a relatively stable grain size and structure during long-term use, preventing the occurrence of cracks, Improve the stability and service life of materials.
