DETAILED INFORMATION
Purohit Pipe Industries is one of the leading , exporters, and suppliers of EN31 Round Bar in India. The EN31 Round Bars are made of pure medium carbon steel and have comparable ductility to mild steel. There are many applications for EN31 Carbon Steel Bar, including tubes, studs, bolts, connecting rods, screws, and rollers. Our company is recognized as one of the leading and exporters of EN 31 Round Bar.
Having nickel, chromium, and molybdenum, EN31 is a very high strength steel alloy that is hardened and tempered before shipping and has high tensile steel strength, ductility, and wear resistance. Despite its relatively good impact properties at low temperatures, EN31 is also suitable for applications at elevated temperatures. Due to their high external strength and good internal strength, EN31 round bars are highly wear-resistant. There is a good combination of ductility, strength, and wear resistance in EN31 steel round bars. Steel alloy EN31 is a very high-strength engineering steel.
Professional craftspeople make EN31 Carbon Steel Bars using the highest quality materials. To satisfy the different needs of our clients, we offer these items in a number of specifications. Our EN31 Round Bars, which have outstanding working strength and characteristics, are used in a wide range of industrial applications. To fulfil the needs of our valuable customers, we a wide range of steel bars in a variety of materials and grades.
