Inconel 625 NiCr22Mo9Nb 2.4856 Nickel Alloy Pipe Fittings

Inconel 625/NiCr22Mo9Nb/2.4856 Stainless Steel Pipe Fittings Nickel Alloy

"zheheng steel" produces and supply Wrought Steel Butt-Welding Inconel 625/NiCr22Mo9Nb/2.4856 Stainless Steel Pipe Fittings ., Non-standard pipe fittings are also produced according to customer requirements. 

Inconel625 is a Ni-Cr-based solid solution strengthened deformed superalloy. It is a solid solution strengthened nickel-based deformed superalloy with molybdenum and niobium as the main strong chemistries. The operating temperature is 950 ° C, and it is good from low temperature to 980 ° C The tensile properties and fatigue properties are good, the processing and welding properties are good, the alloy has excellent corrosion resistance and oxidation performance, and it is resistant to stress corrosion in a salt spray atmosphere.
Inconel625 chemical composition:
Carbon C: ≤ version 0.10,
Silicon Si: 0.50,
Manganese weight Mn: ≤0.50,

Why choose us:

1. All pipe fittings are strictly implemented in accordance with the standards, accept any third-party inspection, and return service.
2. Before leaving the factory, 100% dimensional inspection, 100% spectral test, mechanical and mechanical performance test, pickling, pickling process are mainly aimed at the removal of surface grease and harmful substances, complete surface passivation to prevent oxidation. Some suppliers have not implemented ( Because the surface is not visible to the naked eye after sandblasting) annealing and solid solution (heat treatment), many goods on the market are not heat-treated. When the pipe fittings are in some cold or hot environments, the seam will slowly crack if it is not heat-treated. This process is invisible to the naked eye, surface sanding (many relatively inexpensive processes on the market), bevel ends, etc.
3. Normally, the individual weight of our company's pipe fittings is heavier than that on the market, (Ensure the back arc thickness) to avoid the parts of the same wall thickness that cannot be seen by the naked eye after the processing The pressure is guaranteed, because many suppliers choose the material to the maximum limit in order to minimize the cost.
