AISI 4130 Flanges Are A Low Alloy Steel Grade?
AISI 4130 Flanges are a low alloy steel grade. This low alloy steel 4130 Screwed Pipe Flange contains elements such as molybdenum and chromium as strengthening agents added into their alloy. The carbon content in the 4130 aq steel Blind Flanges is a nominal quantity of 0.30%. With this relatively lower content of carbon in the alloy we use in the manufacture of 4130 annealed steel Socket Weld Flange, comes its excellent weldability properties from the fusion standpoint. Hence, this metal can be welded using any conventional method. The low alloyed 4130 aircraft steel SORF Flanges, generally can be hardened by conducting a heat treatment on the metal.
UNS G41300 Flanges Used Oil And Gas Industries?
As a AISI 4130 Flanges Manufacturer we recommend this alloy to clients all over the world belonging to varying industrial segments, particularly, to industries such as aerospace and oil and gas industries and in the automotive, agricultural and defence industries as well. This is because AISI 4130 Forged Flanges of this alloy grade shows good overall combinations of strength, toughness along with good fatigue strength as well. Since this alloy has good machining properties, simple shaped flanges can be machined following a normalizing treatment on the alloy. On the other hand the more complex shaped AISI 4130 Pipe flange would require an annealing treatment to be performed on the metal.
