The JIS G3106 A572 grade 65 ms steel coil specification is a hot-rolled carbon steel plate for welded structures. The A572 grade 65 ms steel coil steel grades include: SM400A/B/C, SM490A/B/C, SM490YA/YB, SM520B/C, SM570.
The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing A572 grade 65 ms steel coil high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.
X-rays or γ-rays are projected on the surface of the steel plate, and rubber can be placed on the other side of the steel plate. Since the radiation propagates through the steel plate and is absorbed, the intensity is different due to the presence or absence of defects, so the film can record the shape and position of the defects. This A572 grade 65 ms steel coil method is sensitive to the detection of common steel plate defects such as slag inclusions, porosity and pores. The disadvantage is that it is difficult to find the specific depth of the defect and it is not easy to find cracks.
The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of A572 grade 65 ms steel coil nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of A572 grade 65 ms steel coil steel, can be used as an alloying element of low alloy steel.
Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our A572 grade 65 ms steel coil service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's A572 grade 65 ms steel coil customer service to establish a good, comprehensive, full service system.
