Methods of surface quality inspection for GL-DH 32 coal carrier steel plate

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.

GB / T1591 Q345D steel is a commonly used low alloy plate in China. It is equivalent to grade S355J2 in Germany and ASTM A529MGr50 in the United States, with slightly different chemical composition and the same mechanical properties. Under normal delivery conditions, GL-DH 32 coal carrier steel plate, Q345D steel equivalent to S355J2G3 in European standard, and even almost the same performance as the S355J2G4. They can be used interchangeably.

There is an inherent difference between the cold forming properties of low-alloy high-strength steel and carbon structural steel. First of all, a certain amount of permanent deformation of low-alloy high-strength steel requires greater force than GL-DH 32 coal carrier steel plate, carbon structural steel of the same size. Second, when low-alloy high-strength steel is formed, a slightly larger allowable amount for springback should be given. According to experience, unless the low-alloy high-strength steel is processed to control the shape of inclusions, it is necessary to use a larger bending radius than carbon structural steel during cold forming.

GL-DH 32 coal carrier steel plate, SA36 steel plate is one of our main product, it is belong to the carbon and low alloy high strength steel plate. We can supply the different sizes of SA36 steel plate. And the rolling size of SA36 steel plate is following: the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the SA36 steel coil thickness should not exceed 25 mm.

The annual sales volume of steel product is over 300,000 tons, and the sales volume has increased year by year. The business scope covers the Southeast Asia, Eastern Europe, Middle East, Africa, North America, and South America. Client services are mainly in the petrochemical, wind power, shipbuilding, steel structure, machinery manufacturing, and construction industries. Throughout the process, we provide customers with professional personal steel customization services and one-stop solutions, professionally set a variety of futures, fast delivery, and excellent prices.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our GL-DH 32 coal carrier steel plate products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
