Hot Rolled SM490A carbon steel plate sheet Boiler Steel

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating SM490A carbon steel plate sheet production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

Weathering steel SM490A carbon steel plate sheet generally adopts the process route of refined material entering the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and controlled cooling. During smelting, the scrap steel is added to the furnace along with the charge and smelted according to the conventional process.

The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, SM490A carbon steel plate sheet, spring steel must have some characteristics. First, the fatigue resistance of spring steel is good, and it can be restored to its original state after repeated use without deformation. Second, good flexibility. Third, the tensile strength of spring steel is good, under the limit of being stretched, it can be restored without breaking.

Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the SM490A carbon steel plate sheet plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.

S355NL steel plate is under EN10111 standard. We can regard SM490A carbon steel plate sheet, S355NL steel plate as Fine-grain structural steels, normalised rolled. S355NL steel plate is one mainly of Fine-grain structural steels, normalised rolled, The normalized rolled fine-grain structural steel S355NL is characterized by a minimum yield strength of 355 MPa, by good weldability and high resistance to brittle fracture, which is same with DIN:TStE355 and BS:55EE

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.
