Sachiya Steel International is one of the Leading Manufacturer And Exporter of High Quality Alloy Steel F91 Socket Weld Fittings, which resists high temperature embrittlement better than other grades but the effect will still occur after about 10 hours at elevated temperatures. Although our Alloy Steel F91 Forged Socket Weld Elbow Fittings has good high temperature oxidation resistance this grade, like other stainless steels, suffers from embrittlement if held at temperatures above 300 Degree C. We have been able to provide first class quality products of these Alloy Steel F91 Forged Socket Weld Tee Fitting to a large number of clients in the global market.
Our Alloy Steel F91 Forged Socket Weld Cross Fittings contains a minimum of 11.5 % chromium which is just sufficient enough to demonstrate corrosion resistance properties in mild atmospheres, steam, and many mild chemical environments. These Alloy Steel F91 Forged Socket Weld Cap Fitting is a general purpose grade that is often supplied in the hardened but still machinable condition for applications where high strength and moderate heat and corrosion resistance are required.
If our Alloy Steel F91 Forged Socket Weld Coupling Fittings undergoes substantial deformation, then it should undergo a re – anneal or stress – relieving treatment at about 1202 Degree F (650 Degree C). These Alloy Steel F91 Forged Socket Weld Union Fitting can be used in environments containing weak or diluted acetic acid, naphtha, nitric acid and sulphuric acid.
