EN 10216-4 P265NL pipe

1.0453 Steel Pipe and TT St 35N Boiler Tube manufacturer in India

EN 10216-4 Grade p265nl Non Alloy tubes for Pressure vessel, cP255QL (TTSt 35V), 12Ni14 (10Ni14) material equivalent

P265NL EN 10216-4 alloy steel seamless tube consist carbon and also contains a small amount of hydrogen (H), manganese (Mn), nitrogen (N), oxygen (O), phosphorus (P), silicon (Si), and sulfur (S). These elements of en p265nl grade 10216-4 Alloy Steel Tubes are not intentionally added to improve the quality of steel, but are brought in by ore and smelting process, so they are called impurity elements. These impurities have a certain impact on the properties of EN 10216-4 Grade P265NL Alloy Steel Seamless Tubes. In order to guarantee the quality of steel, the chemical composition of all kinds of steel is strictly specified in technical standards.
1.0453 Steel Pipe can be heat treated at 1462°C to 1324°C. Its physical properties are mainly indicated by thermal conductivity, modulus of elasticity, electrical resistance value, specific thermal capacity, density, poison's ratio, coefficient of thermal expansion, etc.
TT St 35N Boiler Tube is used as the part of energy type equipment such as boilers, steam super heaters, steam pipelines and similar type of equipment. It can withstand load at high temperature and pressure.

EN 10216-4 Grade p265nl Non Alloy tubes are a fine grain steel for pressure purposes and are used in power engineering which is associated in the fields of industry. EN 10216-4 P265NL Seamless Alloy Steel Tubes is used as pipes in elevated pressure installations as well as in installation where it is important to ensure the appropriate resilience of steel in varying temperatures.

en 10216-4 p215nl Cold Drawn Seamless Tube which offers uniform tolerances, enhanced machinability and increased strength and tolerances compared to hot-rolled products. It increases the strength of the tube therefore making it very suitable for safety and performance critical applications
