Product Description

EN10305-1 Cold Drawn Seamless Iron Tubes Rolled Precision Steel Pipe S45C C45 CK45 BKS​


EN 10305-1 grade covers steel to produce precision piping grades. The EN 10305-1 Tube is designed with a chemical composition of carbon, silicon, manganese, phosphorus, and sulfur. This gives the EN 10305-1 Steel Tubes good strength and excellent tolerance to high temperatures and corrosive media in stress-induced environments. The EN 10305-1 Material is designed with a tensile strength between 340mpa up to 550mpa. They can be elongated by 22% in the system. Steel Tube EN 10305-1 grade can be precisely shaped in different sizes and dimensions to meet different project requirements. The versatile EN 10305-1 Pipe is widely used in transmission shafts, fuel injection pipes, power steering systems, boiler equipment, heat exchanger tubes, and so on.

The EN 10305-4 grade is designated with a letter E, making the precision tubes adhere to standards and tolerances that are suited for machining parts. EN 10305-4 Pipe is designed keeping in mind there is no room for error or mismatch to take place within the piping system. EN 10305-1 E235 is one of the grades in this precision tubes range. These components have exceptional dimensional tolerance and enhanced accuracy. The EN 10305-1 E235+c grade is designed to be delivered in the cold drawn condition to the buyer. They are available in schedules of SCH 10 to SCH 160 and XXS. The E235+n Pipe is required to be delivered in normalized conditions. These pipes possess tight tolerance and showcase better mechanical properties and hardness. The E235+c Carbon Steel Seamless Tubes are strong components designed by passing hot steel through an extruded metal. These tubes have excellent load-bearing capacity compared to other types of piping equipment in this grade. The modules of this grade produced in India are cheaper than other European countries due to the availability of abundant raw material and labour.
