Hot rolled sheets
Sheets for pipelines and pressure equipment
Sheets rolled in accordance with PN-EN 10028-3 are fine-grain normalized sheets, intended for the production of pipes, fittings and pressure vessels.
Available in thickness from 8 mm to 100 mm in the following grades:
- P355N/P355NH - Yield strength Remin. 355 MPa, Tensile strength Rm within the range 490÷630 MPa, elongation A5min. 22%, CEVmax. 0,43 for ≤60mm, CEVmax. 0,45 dla 60mm < t ≤ 250mm,
- P355NL1 - Yield strength Remin. 355 MPa, Tensile strength Rm within the range 490÷630 MPa, elongation A5min. 22%, CEVmax. 0,43 for ≤60mm, CEVmax. 0,45 dla 60mm < t ≤ 250mm,
Impact strength KVmin. [J] for impact tests for individual temperatures is as follows: -50°C ⇒ 30J; -40°C ⇒ 40J; -20°C ⇒ 50J; 0°C ⇒ 70J; +20°C ⇒ 80J;
- P355NL2 - Yield strength Remin. 355 MPa, Tensile strength Rm within the range 490÷630 MPa, elongation A5min. 22%, CEVmax. 0,43 dla ≤60mm, CEVmax. 0,45 for 60mm < t ≤ 250mm,
