BBN STEEL supply A588 Grade K railway vehicle steel plate specifications range: thickness 8-650mm, width 1500-4020mm, length 4000mm-17000mm, single weight maximum 30.00 tons. Various special specification sheets can be rolled according to customer requirements. Types of steel products: carbon structural steel pipes, low-alloy high-strength steel sheet, steel angles for bridges, steel section for building structures, steel plates for shipbuilding and offshore platforms, steel for boilers and pressure vessels and alloy structures.

Different form A588 Grade K railway vehicle steel, room temperature and medium temperature boiler steel shall have those advantages:Higher room temperature strength;Good impact toughness and low notch sensitivity;As the drum and other parts require a lot of cold deformation during processing, room temperature and medium temperature boiler steel must have good aging toughness;Good processing technology and welding performance;Good macrostructure, etc.

The yield rate is a comprehensive technical and economic index in the production of medium and heavy plates such as A588 Grade K railway vehicle steel. Increasing the yield rate can not only reduce the loss of metal, but it is also vital to the economic benefits of the steel enterprise. The influencing factors of the yield of medium and heavy plates are various, for example, the variety structure, negative deviation rolling level, plate shape control level, cutting loss, rolling waste and burning loss, etc.

The chemical composition difference between A588 Grade K railway vehicle steel, Q235B and 20# steel is as follows:
The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%.
The difference of mechanical properties between A588 Grade K railway vehicle steel, Q235B and 20# steel is as follows:
The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.
