Material advantage

7% low nickel, 3% low molybdenum content, by adding Cr element, 0.3% N content to match 254SMO corrosion resistance. In particular, three characteristics of N content: 1, significantly increase corrosion resistance; 2, improve the material strength; 3, stable austenite structure, more uniform performance.

Material weaknesses

In duplex steel, the base material generally exists in 50% phase state of ferrite and austenite. The equilibrium relationship between ferrite and austenite in welded joints is affected not only by alloying element content in steel, but also by filling metal, welding thermal cycle and protective gas. After the influence of N, pay attention to the root crack. Multilayer welding should also pay attention to the temperature between layers and stress relief heat treatment after welding.

Our company has two main production plants. Zhangjiagang factory is responsible for the rough forming of workpiece, mainly forging process; Hangzhou plant is mainly responsible for precision machining, welding and inspection of products. We implement this layout mainly to use the industrial advantages of each region to achieve maximum economic benefits.

Traditional processing enterprises often do not have such ability, the lack of blank forming ability is unable to achieve the optimal use of materials, resulting in excessive processing allowance, long cycle, high cost. Zhangjiagang is located in the southern jiangsu province, which has the strongest forging capacity in China. It has a good supporting industry and can realize the diversified production of forging and pressing blanks. Thanks to this, the product cycle of our company is faster, the cost performance is higher, and the forging products have better mechanical properties than the products directly processed by rod or plate.

In addition, our company has strong welding ability, which can weld and assemble parts to achieve system delivery. Our company adopts the mode of automatic robot welding and manual precision welding to achieve flexibility and high quality
