Product introduction
EN 10028 P275NH/NL1/NL2
275NH is a weldable fine-grain steel suitable for the fabrication of pressure vessels for pressurised gases and chemicals, industrial boilers, compressors and heat exchangers. The grade is intended for use in moderate to high temperature service.
Other grade types include...
NL1 – is ideal for use in low temperatures
NL2 – is ideal for use in especially low temperatures
offers P275NH from stock and deliver it to you. 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.
