JIS SM490YB plates Hot Rolled Structural Steel Plate

The main applications of JIS SM490YB plates, wear plates: 1. Mining machinery and equipment. 2. Construction machinery and equipment, such as excavators, shovel, sand making machines, etc.. 3. Laying on the ground, wear-resistant plates will be laid on the roads of some construction sites. 4. Construction equipment, excavation machinery, earth moving machinery, compaction machinery, engineering lifting machinery, piling machinery, etc. are all in contact with various kinds of sediment for a long time, and need the support of wear-resistant plates. There are also many equipment that runs repeatedly and frequently, and wear plates are needed.

Over the years, the company has established a standard of JIS SM490YB plates steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to JIS SM490YB plates quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.

Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest JIS SM490YB plates processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain JIS SM490YB plates by rolling method.

The primary purpose of adding alloy elements into steel is to improve the hardenability of steel and to ensure that martensite can be easily obtained during quenching. The second is to improve the tempering stability of the steel, to keep the martensite at a higher temperature, so that the carbide precipitated in the tempered steel is finer, uniform and stable. In this way, under the same conditions, JIS SM490YB plates, alloy steel has higher strength than carbon steel. One of the main purposes of adding alloy elements is to improve the strength of steel.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
