2.P275NH, P275NL1 & P275NL2 – wieldable fine grain pressure vessel steels from our warehouse P275NH is a wieldable fine-grain steel suitable for the fabrication of pressure vessels for pressurized gases and chemicals, industrial boilers, compressors and heat exchangers. The grade is intended for use in moderate to high temperature service.

3.Other grade types include…

NL1 – is ideal for use in low temperatures

NL2 – is ideal for use in especially low temperatures

We offers P275NH from stock and deliver worldwide. Our carbon plates are also tested to the most stringent standards which makes the suitability of our stock even greater and ensures you get a quicker delivery.
