Duplex steel F51/S31803 Stainless Steel Pipe Fittings A403 ASME B16.9 Butt Welding
"zheheng steel" produces and supply Wrought Steel Duplex steel F51/S31803 Stainless Steel Pipe Fittings., Non-standard pipe fittings are also produced according to customer requirements. The company strictly implements ASTM B16.9 / B16.5,ASTM A403 SH3408, SH3409, DIN2605, EN10253, BS1965, JISB2312 and other standards for production.
S31803 is a duplex stainless steel. 22% chromium duplex (austenitic / ferrite) steel (type 2205), with moderate to high strength and good resistance to ordinary corrosion / stress, corrosion / cracking.
The alloy has resistance to chloride environment and sulfide stress corrosion, and its strength is about twice that of standard austenitic stainless steel. When higher mechanical strength / lighter weight is required, the alloy can be successfully used as a substitute for 300 series austenitic stainless steel. F51 is easy to use many standard arc welding equipment for welding zd connection, but it is not recommended for oxyethylene block welding, because carbonization of the welding metal may occur.

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.
Inspection and Test Procedure
1.100% PMI,Spectro Chemical Aanlysis Test for Raw Material
2.100% Dimension & Visual Examination
3. Mechanical Properties Test Include Tension Test,Flaring Test (For Seamless tube/pipe)/ Flange Test (For Welded Pipe & Tube), Hardness Test ,Reversed Flattening Test
4.100% Hydrostatic Test or 100% NON-DESTRUCTIVE Test (ET or UT)
5.Radiographic Test for Welded Pipe (shall be accordance with specification,or shall be as agreed upon between the purchaser and vendor)
6.Straightness Test (optional)
7.Roughness Test (optional)
8.Intergranular Corrosion Test(optional)
9.Impact Test (optional)
10.Grain Size Determinations (optional)
NOTES : ALL THE TESTS AND INSPECTION RESULT NEED TO BE SHOWED IN REPORTS ACCORDING TO STANDARD AND SPECIFICATION.
