General strength SPA-H welded weathering steel sheet properties

Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;

What does steel S460N stand for? the letter S is short for Structural steel. The number 460 stand for the minimum yield strength is 460MPa for S460N steel. The character N is for Normalised rolling when produce in mill. For steel plates S460N, our minimum order quantity shall be above 10 tons for each thickness. For SPA-H welded weathering steel sheet, S460N hot rolled steel plate specification available, our plate thickness ranges from 8mm to 200mm.

The weldability of SPA-H welded weathering steel sheet is good. It means that under certain process and construction conditions, SPA-H welded weathering steel sheet can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.
