AISI 4130 Flanges


AISI 4130 is an alloy which is easily machined by traditional techniques. Machinability is optimum when the API 60k Alloy Steel AISI 4130 Flanges are supplied in a normalized and tempered condition. Though it is possible to machine the alloy in a fully heat treated condition, this property becomes more difficult with an increase in strength as well as the hardness of these 4130 Aircraft Steel SORF Flanges. On the other hand, formability is the best, when the material is in an annealed condition. It is possible to cold work the Alloy Steel 4130 Screwed Pipe Flange by traditional techniques. Since ageing is not possible to be done on this alloy, it is tempered. Tempering the 4130 Forging Pipe Flange aids in restoring some of the ductility that would have been lost. Usually, this metal loses its ductility after the performance of hardening heat treatment, followed with a quench. The 4130 60k Blind Flange is tempered at a temperature range that falls between 750 F and 1050 F. Though the temperature set could be dependent upon the strength level desired. The lower the tempering temperature used on AISI 4130 Flanges the greater the tensile strength.
