carbon-steel-h-beam-suj3 is a kind of Economic section steel, which sectional area distribution is more optimized, the ratio of strength to weight is more reasonable, Mechanical properties of section is more better.It is developed from the I-section steel optimization of a better section mechanical properties of the economic section steel, because its section is same as the English letter "H" ,so be named as H-Beam. Because the various part of H-beam is arranged at right angles, H-beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, so it has been widely used.

carbon-steel-h-beam-suj3 is a measuring tool with a steel, this steel composition and GCr9SiMn bearing steel, its hardenability, hardness and wear resistance are higher than the carbon tool steel, heat treatment size change is not large. SUJ3 is mainly used to manufacture rolling bearing parts such as balls, rollers and bearing rings, etc. They are subjected to high concentrated alternating loads during operation due to the small contact area between the balls and the bearing rings.
