SM490C carbon steel plate sheet vs a36 grade

We are a professional SM490C carbon steel plate sheet steel raw material supplier with a history of 17 years. After years of development, the company's steel plates and coils are widely used in construction, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields around the world. With good product SM490C carbon steel plate sheet quality, we have solid project cooperation with foreign governments or leading enterprises such as Egypt, Bangladesh, Myanmar, Thailand, Philippines, Vietnam, Venezuela, Peru, Mexico, the United States, Portugal, Russia, Iran, Iraq, Pakistan, etc.

The alloy steel plates SM490C carbon steel plate sheet are among our main steel products. There are various alloy steel grades on the market. The most popular alloy steel materials are European material under EN10083-3 and Chinese material under GBT3077 for round bars and GBT11251 for plates. Our typical alloy steel grades are 51CrV4, 25CrMo4, 34CrMo4, 42CrMo4, 12Cr1MoV, 20Cr, 40Cr, 15CrMo, 30CrMo, 35CrMo, 42CrMo, etc.

The weldability of SM490C carbon steel plate sheet is good. It means that under certain process and construction conditions, SM490C carbon steel plate 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.

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 SM490C carbon steel plate sheet 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.

Delivery status: 16MnDR steel plate is normalized or normalized and tempered. 6-60mm16MnDR-40℃ impact, 60-120mm16MnDR-30℃ impact.Ultrasonic testing of 16MnDR steel plates: The SM490C carbon steel plate sheet plates delivered in the normalized or normalized and tempered state with thickness greater than 20mm and the steel plates delivered in the quenched and tempered state with thickness greater than 16mm shall be ultrasonically tested one by one.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, SM490C carbon steel plate sheet sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding.
