Chemical and mechanical properties of S690Q chemical composition

After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, S690Q chemical composition tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of S690Q chemical composition steel and 542,000 tons of steel.

BBN employees work hard and work hard in their work. In life, colleagues care about each other, like a family, and accompany each other at important moments in life. BBN Steel organizes employees to carry out tourism activities every year, so that families can be exposed to nature and relax physically and mentally. The good combination of working and rest can achieve the goal of hard work and happy life.

The main characteristics of S690Q chemical composition, 12Cr1MoV alloy steel plate are as follows:Compared with 12CrMoV steel, 12Cr1MoV alloy steel plate has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is close to the stress rupture strength, and it has high plasticity under the condition of long-term tension. The process and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress relief treatment is required after welding.

Our company's logistics breaks through the perspective that the center of transportation service is ability, and emphasizes that the purpose of transportation service is customer first. Customer demand determines the content and mode of transportation service, while production is often small batch, diversified and consumer demand tends to be diversified. In the case of personalization, our logistics service also provides personalized service projects.

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of S690Q chemical composition etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in S690Q chemical composition etc. steel is strictly controlled.

We have our own factory, including the production and manufacturing of steel pipes, with a special S690Q chemical composition steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements. And has the perfect S690Q chemical composition after-sale service guarantee system, lets the customer save the worry and the labor.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
