What is Q355NH high-speed project steel equivalent steel grade

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and Q355NH high-speed project steel heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported Q355NH high-speed project steel to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Automobile steel plates are mainly used to manufacture automobile beams (longitudinal and transverse beams), frame and other structural parts. Automobile beams not only have to withstand heavy static loads, but also withstand certain impacts, vibrations. Therefore, Q355NH high-speed project steel, automobile steel has certain strength and fatigue resistance, and require good stamping performance and cold bending performance to suit cold punching molding processing requirements.

09CuPCrNi-A weather-resistant steel plate is one of weather-resistant steel (that is, atmospheric corrosion-resistant steel), used in sulfur-containing flue gas, air preheater, economizer, boiler air preheater, to prevent the vicinity of acid dew point, etc. Commonly used is low temperature weathering steel, which has a strong ability to resist low temperature corrosion. This type of steel Q355NH high-speed project steel has a protective effect against corrosion.

Its weatherability is the protection of the oxide layer of weatherproof steel. The mechanism of corrosion resistance of weathering steel is mainly based on the analysis of long-term exposed rust layer. Generally speaking, it is believed that weathering steel can form a dense layer of weathering rust through long-term exposure, which has a good protective effect on weathering steel, Q355NH high-speed project steel.

There are a lot of ASTM standards for pressure vessel steel plates. Such as ASTM A204, A285, A302, A387, A515, A516, A517, A537, A612, A841, etc. Those ASTM steel plates have different thickness ranges. Q355NH high-speed project steel, ASTM A204 plates shall not thicker than 150mm. ASTM A285 plates shall not thicker than 50mm. ASTM A515 plates shall not thicker than 200mm. ASTM A517 plates and A537 plates shall not thicker than 150mm. ASTM A612 plates shall not thicker than 25mm. ASTM A841 plates shall not thicker than 100mm.
