P275NL1 steel plate and equivalent grade

P275 Steel Plate Supplier

P275NL1 is a pressure vessel steel designed for low temperature use. This is done through the reduction of phosphorus and sulphur in the steel. We have one of China’s largest stocks of P275NL1 available for immediate dispatch.

P275NL1 to EN10028-3

The key consideration from the chemical composition is the level of Phosphorus and Sulphur in the steel. The main difference between the NL1 and the NL2 grades is the the reduced % of P and S no metallic inclusions allowed in the steel for lower temperature. This is one of the reasons why P275NL1 from ANSON Steel is so good. Because the whole of the steel making at China is set up to produce extremely low P and S steel – clean steel – our boiler plates often perform significantly better than required by the relevant standard.

EN10028-3 P275NL1 plates are available from 10 mm to 100 mm with some even thicker plates available.

Plate quality is excellent and meets the requirements of many major industrial specifiers on an ex-stock basis. For exceptionally stringent requirements it is possible to order directly from the mill.

We focus on keeping a wide range of plate dimensions to ensure good availability for your projects. Typically stock plates are kept in 2m, 2.5m and 3m widths. Other widths are possible as is profiling of thicker plates and large quantities to your exact requirements. P275NL1 lengths are up to 12 metres, with options at 3m and 6m and less so at 4m and 8m.
