The JIS SM490C plates tensile strength analysis

The company revolves around the long-term strategy of "building a quality base and building a century-long BEBON", adheres to the development ideas of innovation, transformation, and improvement, vigorously promotes transformation and upgrading, structural adjustment, energy conservation and emission reduction, and strives to create high-quality steel with strong core competitiveness and distinctive features The production base has become a green steel city with intensive land use, clean production, efficient use of resources, harmonious and friendly production and environment, business and society, and BEBON characteristics.

In the whole steel structure and steel body, the medium and heavy plate is an important part, once the problem occurs, it is easy to fracture, collapse and occur explosion. So how to judge whether the medium and heavy plate, JIS SM490C plates is of high quality? First of all, check whether there are cracks on the surface of the JIS SM490C plates plate and how glossy it is. Secondly, to measure the thickness error of medium and heavy plate, it is better to use the instrument to measure the bending tensile value. Finally, observe the scale of the steel plate manufacturers, whether there are relevant qualification certificates, and how the production process is.

40Cr steel plate is one of the most widely used steel in machinery manufacturing. After tempering, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel JIS SM490C plates is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15～40mm during oil quenching. When the hardness is HB174～229, the relative cutting workability is 60%. The steel is suitable for making medium-sized plastic molds.

We cooperated with the Peruvian government for many years. And supply them large diameter steel pipes and pipe fittings to support their Hydropower Station Projects. We do 100% UT, RT, Hydraulic test and so on tests for the JIS SM490C plates steel pipes. And do PT, MT and so on tests for the pipe fittings. We published "Welding Procedure Qualification report" after production. And our mill will keep the test record in the documentary department for 5 years. If meet any problems in following application, we can check the test record easily and assist to solve problems at the first time.
