Alloy Steel F91 Threaded Forged Fittings Manufacturer in India

sachiya steel

Sachiya Steel International is one of the Leading Manufacturer And Exporter of Alloy Steel F91 Threaded Forged Fittings, which is not recommended for use in temperatures above the relevant tempering temperature, because of reduction in mechanical properties. Our Alloy Steel F91 Forged Threaded Elbow Fittings has highly resistant to stress corrosion cracking if aged at 550 Degree C or higher, where higher aging temperatures give better SCC resistance. Heat this Alloy Steel F91 Forged Threaded Tee Fitting uniformly up to 1200 Degree F / 1400 Degree F (650 Degree C / 760 Degree C) along with air cool.

For maximum softness, heat this Alloy Steel F91 Forged Threaded Cross Fitting up to 1500 Degree F / 1650 Degree F (815 Degree C / 900 Degree C) along with slow furnace cool. Temper this Alloy Steel F91 Forged Threaded Cap Fittings at temperatures appropriate to produce desired mechanical properties. If this Alloy Steel F91 Forged Threaded Coupling Fittings is tempered in the range 750 Degree F / 1050 Degree F (400 Degree C / 565 Degree C), there will be a decrease in impact strength and in corrosion resistance – depending upon the media.

The tempering range 425 Degree C – 600 Degree C in this Alloy Steel F91 Forged Threaded Bend Fitting should be avoided. Meanwhile, the scaling temperature of our Alloy Steel F91 Forged Threaded Bushing Fitting should be approximately temperature of 650 Degree C.
