Effect of composition on properties of 09cuptire-a weathering steel

09CUPTIRE-A weathering steel surface cracks refer to the linear cracks on the surface of 09CUPTIRE-A weathering steel, which should generally be the same as the forging or rolling direction. Formation reason: it is mainly due to the hairline, hot crack and cold crack caused by surface over burning, decarburization, looseness, deformation and excessive internal stress during processing (forging, rolling, heat treatment, quenching and tempering), as well as the high content of sulfur and phosphorus impurities on the surface. Inspection method: 09CUPTIRE-A weathering steel surface cracks can be detected by naked eye observation, acid pickling, magnetic particle inspection, coloring inspection and metallographic method.

The company has allocated special environmental protection facilities for all 09CUPTIRE-A weathering steel pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, 09CUPTIRE-A weathering steel steel mill scale, environmental protection dust has reached 100%.

In order to improve the 09CUPTIRE-A weathering steel corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main 09CUPTIRE-A weathering steel coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking 09CUPTIRE-A weathering steel sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.

Modern steel-making steel purification facilities and advanced quality control methods have been perfected. Rolling steel can be produced according to controlled rolling and controlled cooling, normalizing, and quenching and tempering processes to produce σs 390-685Mpa series products. 09CUPTIRE-A weathering steel, Low alloy high strength structural steel plate has stable quality, good wear resistance and low temperature toughness. It can be widely used in the manufacture of mining machinery, engineering machinery, high-rise buildings and heavy vehicles.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
