Based on the principle of win-win and mutual benefit, the company operates in good faith, strictly controls the quality, and provides perfect after-sales service, which has won unanimous praise. The success of the company is not only the EN 10025-4 S355ML hard work and wisdom of the company's employees, but also the deep love of the majority of consumers. It also inspires all employees of the company to have the courage to strive. We will continue to innovate and leap forward, create greater brilliance of the enterprise, and make our own contribution to the development of the EN 10025-4 S355ML steel industry.

EN10025-2 S355JR low alloy steel grade is equivalent to GB Q345B in Chinese standard. For the normal thickness, these two steel grades are both owned 345MPa yield strength. Plate S355JR+N indicates that the S355JR steel plate must be done Normalized heat treatment when rolling for improve the steel strength and weldability. Our mill would roll EN 10025-4 S355ML, S355JR alloy steel plate under as rolled or control rolled when customers' have not requested any heat treatment in their P/O.

The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with EN 10025-4 S355ML, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.

EN 10025-4 S355ML, Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.

EN 10025-4 S355ML, 13CrMo44 steel plate is a kind of steel which with Cr, Mo,Cr-Mo and mainly used for pressure vessels. The steel grade 13CrMo44 is according to DIN 17155 standard which with the yield strength of 242MPa. The DIN 17155 13CrMo44 steel plate chemical composition is the content of C is 0.15, Mn is 2.00, S is 0.03, Cu is 0.30, Si is 1.00, P is 0.045, Cr is 17 or 19 and the Ni is 8 or 10.

We are specialized in offering hot rolled ASTM A516 steel plate, which are used in various engineering applications and can be availed in various grades like carbon steel EN 10025-4 S355ML A516 Grade 60 steel plate , A516 Grade 65 steel plate, A516 Grade 70 boiler steel plate, ASTM A516 GRADE 60 plates Trippled Certified, ASTM A516 GRADE 60 Plates Dual Certified. Our boiler plates are available in the form of steel plate, steel sheet, steel sections. If you are interested in EN 10025-4 S355ML boiler plate, welcome to contact us.

The results of adopting two-level EN 10025-4 S355ML service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and EN 10025-4 S355ML after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
