The characteristics and uses of Q355NHB weathering steel plate

1. Q355NHB weathering steel plate grade introduction
Q355NHB is a weather-resistant steel plate, which also belongs to the low-alloy series. The letter Q is the first letter of the Chinese phonetic alphabet for yielding. The number 355 refers to the yield strength of 355MPa. The letter HN is the first letter of Chinese phonetic alphabet weather-resistant. The letter B stands for level. Q355NHB weathering steel plate has the characteristics of rust resistance, corrosion resistance and longevity of components, thinning and consumption reduction, and labor and energy saving.

2. Q355NHB weathering steel plate characteristics:
Q355NH steel plate has the properties of high-quality steel such as toughness, ductility, forming, welding and cutting, abrasion, high temperature, fatigue and so on.

3. The use of Q355HNB weathering steel plate:
Q355NH plate is mainly used for steel structures exposed to the atmosphere for a long time, such as railways, vehicles, bridges, and towers. Weathering steel is mainly used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive medium in chemical and petroleum equipment.
