Weldable normalized fine grained pressure vessel steels description
The fine grained pressure vessel steels grades rolled under normalised conditions offer good cold-forming and hot-forming properties without negatively affecting the material properties. These steel grades are therefore also suitable for cold-bordering and cold-flanging as well as for cold-bending and cold-folding, considering the bending radii according to DIN 6935 for a steel grade of corresponding strength. With coldforming above 5% or hot-forming outside of the temperature range of 850 - 1.000 °C as well as after excess times, the steels rolled under normalised conditions should be subsequently normalised at 900 - 950 °C. The holding time after temperature equalisation should be approx. 1 minute per millimetre of plate thickness.

Weldable normalized fine grained pressure vessel steels Application
These fine-grain pressure vessel steel grades are characterised by a minimum yield strength of 275 - 460 MPa, by good weldability and high resistance to brittle cracking. These grades are used above all for manufacturing vessels for pressurised gas (LPG, butane and propane tanks), pressure vessels, steam boiler parts, pressure piping, compressors etc.
The following special grades are available for extraordinary applications:
P...NL1 and P...NL2 or P...ML1 and P...ML2 for application temperatures below -20 °C;
P...NH for operating temperatures of up to 400 °C.
The user of these steel grades must make sure that his calculation, design and processing methods are appropriate for the material. The welding technique used must be suitable for the intended application and comply with the state-of-the-art.

The main grade of  Weldable normalized fine grained pressure vessel steels are :

1) If N is additionally fixed by means of Nb, Ti or V, the minimum Al content is not determined.
    If N is only fixed with Al, then: Al/N ≥ 2.
2) Cr ≤ 0,30 %, Mo ≤ 0,08 %, Cr + Cu + Mo ≤ 0,45 %
3) Nb + V + Ti ≤ 0,15%
4) For thicknesses < 6.0 mm, aminimum content for Mn 0.60% is permitted.
5) Nb + V + Ti ≤ 0,05%
6) Nb + V + Ti ≤ 0,12%
7) The minimum value for Altotal does not apply if sufficient amounts of other nitrogen-fixing elements are present.
