A573 Grade 70 rolled structural steel delivered to North Korea

According to the guarantee conditions of delivery, China and some countries divide the ordinary carbon steel into three categories: Class A steel, which only guarantees the mechanical properties, not the chemical compositions； Class B steel, which only guarantees the chemical compositions, not the mechanical properties; special steel (Class C steel), which not only guarantees the chemical compositions, but also the mechanical properties. Class C steel A573 Grade 70 rolled structural steel is often used to manufacture important structural parts. Density of ordinary carbon steel: 7.85 g / cm3.

The Philiphine customer is our old customer, and they are engaged in offshore oilfield resources drilling projects. Thus they have regular steel demands. They ordered 1008 tons API 5L grade B ERW pipes and Q345B seamless pipes from us in April 2018. And told us that is a regular demand almost every two month. Since our first success cooperation, we have cooperated with each other regularly. And they also bring us new opportunities and signification in Philippians market.

Boiler steel mainly refers to materials used to make superheaters, main steam pipes and heating surfaces of boiler fire chambers. Boiler steel is a totally different material from A573 Grade 70 rolled structural steel. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength, alkali corrosion resistance, and oxidation resistance. Commonly used boiler steels include open-hearth smelted low-carbon killed steel or electric furnace smelted low-carbon steel, with carbon content Wc in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steel has also been used to build boilers.
