What is SPA-H welded weathering steel sheet equivalent material

The company has a mature technical team whose reponsibility is to design the drawing, choose suitable material and evaluate the whole production processaccording to customers’ requirement. The company is led by talents and technology, and comprehensively promotes its six business segments like steel material supply, precision steel casting, environmental protection equipment, household appliance, SPA-H welded weathering steel sheet steel structures and oil tank projects. Seeking new developments in new technology and business areas, and fostering a large number of industry-leading, international-level projects.

At present, China's wear-resistant steel plate grades are divided into six levels, namely NM300, NM360, NM400, NM450, NM500, NM550 and NM600. The wear-resistant steel SPA-H welded weathering steel sheet grade adopts the combination of Chinese NM of wear resistance meaning and Brinell hardness (HB) value. For example: NM500, NM is the first universal parent of Chinese "wear resistance", "500" is Brinell hardness value. NM series wear-resistant steel has good wear resistance, which greatly reduces the loss and use cost.

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.

Laser cutting, it is a specific way of cutting SPA-H welded weathering steel sheet steel plate cutting processing, is also one of the common way of cutting its on the cutting or machining parameters, if you want to get the right number, is that you can adjust these parameters to achieve a goal, adjust a few times more to get accurate numerical right in addition, we also need to know is, the faster the cutting SPA-H welded weathering steel sheet speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.

The company specializes in hot rolled plates producing, steel plate processing, steel plates cutting, carbon steel plate weldding and exporting of wide and thick steel plates. BBN company has high-quality CNC SPA-H welded weathering steel sheet steel plate cutting processing equipment, professional technical personnel, and supporting marketing and after-sales service system.
