P355NH 1.0565 Introduce
P355NH is steel for pressure purposes (P) with minimum yield strength of 355 MPa (355) which has specified elevated temperature properties (NH). A pressure vessel steel grade with good weldability and high resistance to brittle cracking, P355NH is used by the world’s fabricators for the manufacture of pressure vessel tanks for the storage of pressurised gases.
We are leading Manufacturer, Supplier & Exporter of high quality EN 10216-2 Alloy Steel Seamless Pipes. These are manufactured in conformance with the international quality standards. These are used in varied engineering applications as well as in high temperature pipelines, boiler tubes and other areas. We offer these seamless pipes in different size, grades, thickness & Specification demanded by the clients. These pipes are used in various application industry like petrochemical, engineering, chemical, oil and gas and other industrial etc. We also offer our clients in competitive prices in the market.
This EN 10216 specifies the technical delivery conditions in two test categories for seamless tubes of circular cross section,with specified elevated temperature properties,made of non-alloy and alloy steel. NOTE This Part of EN 10216 may also be applied for tubes of non-circular cross section;necessary modification should be agreed a the time of enquiry and order.
