Description
EN Specification seamless steel tubes are used for high temperature service applications including Boiler, natural gas, pressure pipe, pipe for ship, structure pipe etc. .Seamless Steel Tubes according to EN 10216-1 Grade P235TR1 are reheated and furnished in full annlealed, isothermal annealed or normalised quenched and tempered condition .EN 10216-1 Grade P235TR1 Alloy Steel Seamless Tubes have a typical chemistry with additions of max 0.30 Chromium and max 0.30 Molybdenum. Bearing minimum tensile strength of 360 Mpa and maximum tensile strength 500 Mpa, EN 10216-1 Grade P235TR1 Tubes have a minimum yield strength of 235 Mpa.
The alphanumeric TR1 for qualities without specified aluminium content, impact properties and specific inspection and testing requirements
The alphanumeric TR2 for qualities with specified aluminium content, impact properties and specific inspection and testing requirements.
