EN10305-1 E235 Seamless Cold Drawn Tubes Low Carbon Steel for Vessel Construction
We are YUHONG GROUP , one of the biggest manufactures of stainless steel & duplex steel & alloy steel tubes and pipes in China. With development more than 33 years, we have accumulated a great many clients all around the world and Yuhong products also won the great praise among the customers.
Description
Grade E235 or as referred to as EN 1.0308 steel is a non-alloy carbon steel grade. Essentially, E235 is the chemical designation for the English standard. The EN 10294-1 Grade E235 is an unalloyed steel that is well suited for machining without the use of a heat treatment.
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.
