G41400 Blind Flanges and SAE 4140 Industrial Flanges Manufacturer in India

Alloy steels tend to have improved properties over carbon steel grades. Grade 4140 is an alloy steel that delivers a good performance because of its higher alloying content, making it suited to several industries. AISI 4140 Flanges contain inclusions of chromium, molybdenum, and manganese. It is categorized as low alloy steel because the content of the alloying elements in the material is less than 5% of its total weight. Yet, it remains a ductile grade, which could be formed into various shapes including the UNS G41400 Threaded Flange.

AISI 4140 Flanges

It is not easy to construct threads on alloys that do not have ductility. In such cases, the construction of threads could easily destroy the surface, making it unsuitable for use. It is possible to shape them in an annealed condition because the material remains ductile. However, the formability of the alloy is tougher in comparison to plain carbon steels, therefore forming the SAE 4140 Industrial Flanges requires more force. As with most steel alloys, it is heat treated by normalizing, followed by hardening, and quenching by cooling in air. This heat treatment offers good results as the AISI 4140 Pipe Flanges has improved durability and good toughness. The other characteristics of this material include high fatigue strength, with resistance to both abrasion and impact. These properties are important in demanding industries such as the oil and natural gas or petroleum industry, where the DIN 1.7225 Welding Neck Flange is put through high stresses. Hence, the need for improved tensile and mechanical properties, in comparison to the very basic carbon steel alloys. Although the alloys have low contents of elements in their material composition, the corrosion resistance properties of the G41400 Blind Flanges are an improvement over traditional steels.
