The alloying elements of low alloy steel are less than 5%. The low alloy steel is added one or several alloy elements on the basis of carbon steel to improve the performance. Such as manganese, silicon, aluminum, nickel, copper, boron, phosphorus, rare earth, etc. en 10149 2 hot rolled pickled and oiled steel coil Steel with one or more of these elements will have the advantages of high strength and toughness. Due to the addition of few alloy elements, it is called low alloy high strength steel.

Welded pipe, also known as welded steel pipe, refers to the steel pipe made of steel plate or strip steel after crimping and forming, with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are diversified, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. en 10149 2 hot rolled pickled and oiled steel coil, Welded pipes have many uses and are almost ubiquitous in our lives. However, when choosing welded pipes, we must pay attention to performance and material characteristics.

en 10149 2 hot rolled pickled and oiled steel coil, Nickel-based alloys are widely used in petrochemical, metallurgy, energy, and machinery because of their high room temperature and high temperature strength, good oxidation and thermal corrosion resistance, excellent creep and fatigue resistance, good structural stability and reliability. , Building materials, medicine, environmental protection and other industries. The company has developed N08825, N06625, N06600, N06690, N06601 and other nickel-based alloy tube blanks and steel pipe products, which have been implemented in batches in the petrochemical industry.

The difference between en 10149 2 hot rolled pickled and oiled steel coil, 10# seamless steel pipe and 20# seamless steel pipe:
1. Chemical composition
