For S420NL weldable fine grain structural steel plate, it is produced under specification EN 10025-3. The yield strength of S420NL plate shall be above 420Mpa for the thickness below 16 millimeter, 400MPa min. for thickness below 40mm, 390MPa min. for thickness below 63mm. The tensile strength for thickness below 100mm of this steel grade S420NL shall be within 520-680Mpa. For the Mill test certificates of steel S420NL,Steel SA573 Grade 70 Plate, our mill would like to issue format according to EN 10204 3.1.
DIN 17102 TStE355 is mainly used for grain structure steel and normal rolling steel. Tste355 steel plate is a kind of grain structure steel. It is a standard rolled steel plate / sheet specially manufactured for different types of welding structures. It is made of basic materials, with high temperature resistance and low temperature resistance. Product Steel SA573 Grade 70 Plate is suitable for pressure boiler, mobile and vertical storage tank, high pressure pipeline, bridge, mast, cable, etc.
How to distinguish between hot rolled and cold rolled process?The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, Steel SA573 Grade 70 Plate, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.
The steel plate, steel pipe and other steel materials are the important material in the material engineers. Our company will provide the high quality the steel plate, steel pipe and other steel materials for you. We are exported the steel plate, steel pipe and other Steel SA573 Grade 70 Plate steel materials to the customers from USA, South America, Europe, Africa etc. If we can have the good cooperation together, you will be very welcome to be our agent in your local market.
