JIS carbon steel SM490YB CS plate material equivalent standards

Thin steel plate is a kind of steel plate material that is thinner in thickness. Generally, steel plate with thickness less than or equal to 4mm is called thin steel plate. As we all know, the steel products we usually see are also divided into different thicknesses. The strength, performance and scope of application of different thickness steel plates, JIS carbon steel SM490YB CS plate are also different. Today, we will talk about some related knowledge of thin steel plates, and take you to understand the characteristics and uses of thin steel plates.

At the same time of doing well in JIS carbon steel SM490YB CS plate production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the JIS carbon steel SM490YB CS plate technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

Titanium microalloying is an element of JIS carbon steel SM490YB CS plate strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in JIS carbon steel SM490YB CS plate tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

Temperature has a great influence on the strength of the material, JIS carbon steel SM490YB CS plate. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.
