How to repair corrosion pits on A573 Grade 70 rolled structural steel

The company specializes in the research and development, production and sales of A573 Grade 70 rolled structural steel seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has A573 Grade 70 rolled structural steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,A573 Grade 70 rolled structural steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

The company's main steel plates have twelve types of steel products like boilers and pressure vessels, low-alloy high-strength steel A573 Grade 70 rolled structural steel, wear-resistant steel plates, corrosion-resistant steel plates, high-rise building structural steel plates, marine structural steel plates, alloy structural steel plates, mold steel plates, carbon structural steel plates, shipbuilding and steel plates for oil production platforms, composite steel plates, steel plates for oil and gas pipelines. We offer various steel grades, and more than 300 kinds of thickness specifications.

The metallurgical quality of spring steel should reach the level of high quality steel. Due to the special requirements of production parts, A573 Grade 70 rolled structural steel, spring steel must have some characteristics. First, the fatigue resistance of spring steel is good, and it can be restored to its original state after repeated use without deformation. Second, good flexibility. Third, the tensile strength of spring steel is good, under the limit of being stretched, it can be restored without breaking.

We have a large number of A573 Grade 70 rolled structural steel steel materials in stock, and provide deep processing services such as welding. In addition to simple welding parts, we can also weld H-beam, box column and other profiles. For such welded structure, our advantage is that there are high-quality and low-cost raw material steel plates, which can be cut into the A573 Grade 70 rolled structural steel required size and welded into steel products with required shape and size, without being limited by the specifications of rolling production lines

Our produced Grade A normal strength shipbuilding steel are certified by CCS, BV, LR, ABS, DNV, GL, KR and NK ABA/ ABS Grade A marine steel plates are suitable for use in the construction of container ships and large cargo freighters and commercial shipping lines such as luxury cruise ships and ferries,A573 Grade 70 rolled structural steel., ABS Grade A Steel Plates Size and Specification Thickness: 3~150mmWidth: 1219~3200mmLength: 2500~12000mm

Our company regularly visits customers, consults and follows up the after-sales service, and directly solves problems for customers. In the use of our steel materials, whether quality problems or not, the after-sales will help solve the problem as soon as possible. We promise free life-long replacement for any product quality problems. The sound after-sales service system make you free from worries.
