EN 10216-4 P255QL Seamless Steel Tube / Pipe

EN 10216-4 is the standard specification for seamless steel tubes for pressure purposes – Technical delivery conditions – Part 4: Non-alloy and alloy steel tubes with specified low temperature properties. P255QL, with a steel number of 1.0452, is one of the non-alloy quality steel grades designated by EN 10216-4. The EN 10216-4 P255QL seamless tubes are often used in services with a minimum temperature of -46°C.

Heat treatment conditions

For low-temperature purpose, EN 10216-4 P255QL shall be fully killed. The capital letter “P” stands for pressure purposes; “255” indicates the minimum yield strength of 255 MPa; “Q” indicates the heat treatment as quenching and tempering; “L” indicates the use for low-temperature purposes.

Usually the seamless tube or pipe of grade P255QL shall be quenched and tempered. The quenching temperature(hardening temperature) shall be at 890°C to 930°C while tempering temperature is ranging from 600°C to 680°C.

16Mo3 Steel Plates and Pipes for Power Plant Piping

In 25th September 2015, Hebei Metals Industrial Limited received a large order from BULMFELD, who is a German contracting company dedicating to power-station solution in Europe. The order is for a power plant project in Czech Republic. Considering the high temperature conditions, 16Mo3 / 1.5415 as well as its ASTM equivalent(ASTM A335 Gr.P1 / ASTM A204 Gr.A and Gr.B) are specifed to meet the European design code. The 16Mo3 steel plate manufactured to EN 10028-2 is required for prefabrication of the pressure vessel while 16Mo3 steel pipes(seamless) made to EN 10216-2 are required for the heat-exchanger piping.
