How to select the qualified S355M steel equivalent

The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural S355M steel equivalent steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.

S355M steel equivalent, No.45 seamless pipe belongs to high strength medium carbon steel, with certain plasticity and toughness, high strength and good machinability. Good comprehensive mechanical properties can be obtained by quenching and tempering treatment. In addition, the hardenability of No.45 seamless pipe is poor, and the water quenching is easy to produce cracks. After quenching and tempering, the small and medium-sized parts can obtain better toughness and higher hardness. For large parts (the section size is more than 80mm), normalizing treatment is appropriate. But the weldability of No.45 steel is poor. The weldment should be preheated before welding and annealed after welding to eliminate welding stress.

Alloy steel plate is a kind of high strength steel plate with excellent performance in all aspects. In the current market environment, the performance requirements for steel plate are also higher and higher, ordinary steel plate has been far from meeting the market demand, and the emergence of alloy steel plate has broken this deficiency. The alloy steel plate is improved from the traditional steel plate, which is a new high improvement to the performance of the traditional steel plate. Today let us have a learn of S355M steel equivalent, alloy steel plate together.

Oxygen is a harmful element in S355M steel equivalent steel. With the increase of oxygen content, the strength of S355M steel equivalent steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of S355M steel equivalent steel.

Medium and heavy plate S355M steel equivalent inventory spot: 23*3190*9220, 23*2470*8400, 22.5*3050*7300, 23*3500*10800, 21*3500*8840, 22*3400*11550, 29.5*1750*7150, 25*2500*12000, 27*1500*5000, 36*2720*7950, 27*1920*6000, 25*2630*3300, 26*3480*6000, 27*1800*6000, 23*2430*12370, 22.5*2560*6000, 43.5*1600*6000, 28.5*2500*6700, 32*1850*6000, 27.5*3100*6390, 48.5*1600*6000, 23.5*3300*14000, 33*3500*7050, 50*1600*6000.

For ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates, our company would issue the original mill test certificate S355M steel equivalent EN 10204 3.1 for clients when arrange delivery, so that clients can trace the A573 Gr.70 plates origin easily.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
