What the different between SS400 and Q235 ?

Posted:2015-11-30 21:47:25

SS400 substantially identical to our Q235 ( equivalent Q235A use ) . But differ on specific indicators , Q235 content of C, Si, Mn, S, P and other elements have made a request, but only requires SS400 S, P less than 0.050 . Q235 is greater than the yield point of 235 MPa, and a yield point of SS400 245MPa.SS400 ( general steel structure) , which means that the general tensile strength greater than 400MPa structural steel . Q235 yield point is greater than the mean for the ordinary carbon steel of 235MPa . SS400 Standard No. JIS standard number G3101-1995.Q235 of GB / T700-2006.

SS400 is a way of marking the Japanese steel , in fact, is the number of domestic Q235 steel . It is a steel material . Q represents the yield of this material , behind the 235 , the yield refers to the value of this material at about 235 . And will increase the thickness of the material and its yield value decreases . Because the carbon is moderate, better overall performance , strength, ductility and welding performance is better with the most widely used. Often rolled into wire rod or bar, the steel , flat steel, angles, beams, channels, steel and other steel window frames , thick steel plate . Widely used in construction and engineering structures . Or the construction of factories for the production of steel frame house , high-voltage transmission towers, bridges , vehicles, boilers , containers, ships, etc. , are also widely used as the performance of less demanding mechanical parts. C, D grade steel but also for some professional use of steel .
