Who makes EN steel grade S275NL material steel plates

From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. EN steel grade S275NL material, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.

Strip steel is mainly divided into hot-rolled ordinary strip steel, cold-rolled ordinary strip steel, hot-rolled high-quality strip steel and cold-rolled high-quality strip steel. The EN steel grade S275NL material, hot-rolled carbon strip steel is made of ordinary carbon structural steel, and is hot-rolled into strip steel with a thickness of 1.80-6.00mm and a width of 50-1200mm. The hot-rolled carbon strip steel is mainly used for the manufacture of cold-rolled billets, cold-formed steel billets, welded steel pipe billets, bicycles, and small hardware products.

Q690D material is a Chinese standard high-strength welded structural steel.What does Q690D stand for? Q represents the yield strength, 690 represents the yield strength value, and D represents the quality of the Q690 steel. The quality grades are A, B, C, D, and E, respectively. The impact of Grade D steel plate is﹣20°C. Q690D executive standard: GB / T1591-2008. EN steel grade S275NL material, Q690D steel has high yield strength and tensile strength.
