We can process the steel materials according to your drawing. Or if you can not make drawing, please send us bending radius S420ML specific data and requirements, our technical department can make design and drawing for you, and then confirm with your technician or engineer. If all is OK, our processing center will process the steel materials according to the drawing. So no matter what size and shapes you need, we can meet demands at the most time.

The types of carbon steel are basically as the following: bending radius S420ML, Carbon structural steel, which is mainly used in various projects. High-quality carbon structural steel, whose main purpose is for important parts. Carbon tool steel, which is mainly used to make various small tools. Cast carbon steel parts for general engineering, which are mainly used for complex parts that are difficult to form by forging and other methods and require high mechanical properties.

Ultrasonic flaw detection emits ultrasonic waves to the bending radius S420ML steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the bending radius S420ML steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.

The requirements for toughness impact energy of bending radius S420ML, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.

Our ogistics department has a professioanl team to support the goods’ transportation and delivery time. Its responsibilities: make customs clearance documents, track products production process, and update shipping information for customers. The company will adhere to the mission of reflecting social values, take the scientific management system as the guarantee of daily operations, and provide continuous technological innovation to support its sustainable development.

Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products bending radius S420ML are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.
