What is SA573 Grade 65 chemistry structural steel?

With high-quality SA573 Grade 65 chemistry steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our SA573 Grade 65 chemistry steel market and improved the control of steel plate production quality.

SA299GrB steel plates with a thickness of less than or equal to 50mm are usually delivered in the rolled state, and can also be delivered in the state of normalizing, stress relief, or normalizing plus stress relief. Steel plates with a thickness greater than 50mm should be normalized heat treatment. It can also add flaw detection standard requirements, flaw detection level requirements, alloy element composition control requirements, etc. according to needs.

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of SA573 Grade 65 chemistry, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.

"The production method of seamless steel pipe can be roughly divided into cross rolling method (menesmann method) and extrusion method. The cross rolling method (menesmann method) is to pierce the tube blank with the cross roll first, and then extend it with the rolling mill. This method is fast in production, but requires high machinability of tube blank. It is mainly suitable for producing carbon steel and low alloy steel tube, SA573 Grade 65 chemistry tube.The extrusion method is to pierce the billet or ingot with a piercer, and then extrude it into a steel tube with an extruder. This method is less efficient than the cross rolling method and is suitable for the production of high-strength alloy steel tubes."

SPA-C steel with the thickness range is 1.2-150mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the SA573 Grade 65 chemistry, SPA-C steel coil thickness should not exceed 25 mm. SPA-C steel’s mechanical properties is yield strength more than 325 MPa, tensile strength more than 450Mpa.

The company has a high-quality management, technology and R&D team, and adopts independent research and development, domestic innovative process optimization combination. Relying on advanced manufacturing technology and sophisticated production testing equipment, it has ensured the high quality of products SA573 Grade 65 chemistry and won a good reputation. We can offer various kinds of steel materials in GB, ASME, ASTM, JIS, DIN, EN, API standards and specifications.

From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
