Grade SF440 is a carbon steel alloy that is used for general structural applications. This carbon steel has tensile strength property that ranges from 440 Mpa - 540 Mpa, which is considered to be good, especially since the SF440 Flanges find use in structural purposes. The content of carbon in this alloy is about 0.6%. Hence, the alloy has a higher hardness. Generally, the higher the amount of carbon in the steel’s chemical composition, the higher is its level of hardness. A hard Astm Sf440 Steel Flange is suited to demanding applications, especially in structures that require higher mechanical properties. For instance, in the oil and gas industry, which requires durable components, these components prove to be useful, especially in refineries & sour wells.
Although the Sf440 Weld Neck Flange is not resistant to corrosion, they have better mechanical properties, suited to industries like petrochemical, acid processing, nuclear power in addition to oil refineries. It is possible to improve the tensile properties of the Ansi B16.5 Carbon Steel Sf440 Orifice Flange, with the use of heat treatments. Annealing the alloy improves its toughness reduces the inner or residual stresses while reducing excessive hardness and improving its ductility. On the other hand, normalizing or normalizing with tempering improves (refine or modify) the grains of the Carbon Steel SF440 Flanges alloy. Furthermore, the dimensional stability is much better, and the alloy becomes more responsive to the case hardening. Tempering the Sf440 Carbon Steel Flange brings about a balance between the mechanical properties. Usually, in a carbon steel alloy that contains high levels of carbon in its chemistry, the material remains very hard, almost to the point of embrittlement. A brittle material is easily affected by a slight change in pressure. Tempering the Sf440 Jis Flange essentially keeps a check on the hardness and toughness ratio.
