Q355NE is a low alloy high-strength plate , Q on behalf of the yield strength "yield" initials, 355 is the yield strength of the steel plate can not be less than 355 (MPa), the letter N indicates normalised or normalised rolled (Q355NE default delivery status for normalised rolled), but also according to the customer requirements for the normalised state delivery. B represents the level of steel plate, that is, the impact temperature. Different grades can be expressed as: Q355NB, Q355NC, Q355ND, Q355NE.
Q355NE adopts electric furnace steelmaking, which is made from scrap iron, and the steel quality is pure, and the steel plate is poured with molten steel and pressed into flat steel after cooling. It is flat, rectangular, and can be rolled directly or sheared from wide steel strip. Steel plate by thickness, thin steel plate <8 mm (the thinnest 0.2 mm), medium-thick steel plate 8 ~ 60 mm, extra-thick steel plate 60 ~ 120 mm.
Q355NE executes GB/T1591-2018 standard production, size and shape and permissible deviation: the size, shape, weight and permissible deviation of Q355NE are in accordance with the provisions of the corresponding standards of GB/T709-2019.
