Welcome to Henan BBN Steel
SM490A steel plate is a low-alloy high-strength steel. It is a structural steel produced in accordance with Japanese standard JIS G3106. Its strength σb is 490MPa. It is mainly used for buildings, bridges, ships, rail vehicles, petroleum storage tanks, containers and other buildings that require advanced weldability. EN 10025 S355ML steel supplier, JIS SM490A steel sheet delivery status: steel plates with a thickness of <80mm, the delivery state is hot-rolled; steel plates with a thickness of ≥80mm, the delivery state is normalized condition.
In recent years, in line with the development trend of iron and EN 10025 S355ML steel supplier steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which EN 10025 S355ML steel supplier are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
Laser cutting EN 10025 S355ML steel supplier has no burr, wrinkle and precision is high. It is superior to plasma cutting. Laser cutting has good cutting quality, narrow cutting width (generally 0.1-0.5m m), high accuracy (generally 0.1-0.4mm hole center distance error, 0.1-0.5mm contour dimension error), good surface roughness (generally Ra is 12.5-25μm), and the EN 10025 S355ML steel supplier cutting seam can be welded without further processing. Fast cutting speed: for example, with 2kW laser power, the cutting speed of 8mm thick carbon steel is 1.6m/min.
The hardness of the steel plate is very high, so special equipment is needed to complete the processing and cutting of these materials, EN 10025 S355ML steel supplier. In order to cut the plate into an ideal size, the steel plate cutting needs to use natural gas flame for preheating, which will generate a large amount of oxygen flow during the operation. These substances will oxidize the steel plate, and then form a cutting edge, then the cutting operation process is basically completed. In the actual processing work, there are many different classifications for steel plate cutting.
