How to improve toughness of s355jr low alloy steel

Rotability of low-carbon steel sheet, a variety of s355jr low alloy steel low-carbon steel sheets with different metallographic properties and mechanical properties were subjected to deep-drawing spinning tests, from which the following points are directly related to the rotatable properties. The maximum elongation strain of aluminum killed steel plate of general purity exceeds 250% during deep drawing and spinning. The ultimate elongation of the boiling steel sheet with lower purity decreases with the increase of the oxygen content of the steel sheet.

Hot rolling and cold rolling are all the processes of forming steel plates or profiles, which have a great influence on the structure and properties of steel. The rolling of steel is mainly hot rolling, and cold rolling is usually used to produce small size steel and thin plate. With the development of new technologies such as the precision of hot rolling size, shape and surface quality and the continuous emergence of new products, s355jr low alloy steel, hot rolled steel strip and steel plate are widely used and have more and more competitive strength in the market.

s355jr low alloy steel, JIS 3101 SS540 is high strength low alloy steel plate sheet, which is widely used in plants building, general mansions and all kinds of construction machinery, such as mines and various types of drilling rig used in construction, power shovel, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers , various types of cranes, hydraulic support, coal mining machinery and equipment and other structures.

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.
