JIS carbon steel SM490YB CS plate H beams

Delivery status: Hot-rolled JIS carbon steel SM490YB CS plate steel In the hot-rolled state or controlled rolling state or heat treatment, the state of delivery, cold-rolled steel to the annealing state of delivery.

The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep JIS carbon steel SM490YB CS plate processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and JIS carbon steel SM490YB CS plate steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the JIS carbon steel SM490YB CS plate rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of JIS carbon steel SM490YB CS plate steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.

Manganese steel plate is a kind of common steel, which is a kind of high-strength anti manganese steel. JIS carbon steel SM490YB CS plate, Manganese steel plate is mainly used to bear the impact, extrusion, material wear and other severe working conditions. It is a typical anti-wear steel, with austenite and carbide as cast structure. After water quenching at about 1000 ° C, the structure changes into single austenite or austenite with a small amount of carbide.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel JIS carbon steel SM490YB CS plate products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
