The difference between duplex stainless steel and stainless steel?

The difference between duplex stainless steel and ordinary steel: duplex stainless steel has the characteristics of austenitic stainless steel and ferritic stainless steel! In other words, it has the characteristics of stainless steel and carbon steel! Compared with ferrite, it has higher plasticity, toughness, no room temperature brittleness, resistance to intergranular corrosion and high weldability, ferritic stainless steel to maintain 475℃ high brittleness, high thermal conductivity, superplasticity. Compared with austenitic stainless steel, it has high strength, intergranular corrosion resistance and chloride stress corrosion resistance. Duplex stainless steel has excellent corrosion resistance and is also a nickel stainless steel. 2507…

Can galvanized rust？

Galvanized sheet, galvanized iron wire, galvanized pipe and other galvanized products in the normal environment is not easy to rust. However, if it is improperly kept or affected by the external environment, rust may occur. The following is the situation that may lead to the rust of galvanized products: Galvanized layer damage: if the galvanized layer is scratched by sharp objects, or damaged during transportation, installation, etc., it will lead to the destruction of the galvanized layer, so that the internal metal is outside and easy to rust. Environmental factors; High humidity environment, salt spray environment, acidic environment and…

What is the production process of color coated rolls?

The production method of color coated coil is: on a continuous unit, cold-rolled strip steel and galvanized strip steel (electric galvanizing and hot dip galvanizing) are used as the base plate. After surface pretreatment (degreasing, chemical treatment), one or more layers of liquid coating are applied by rolling coating method, and the sheet obtained after baking and cooling is coated steel plate. Because the coating can have a variety of colors, the coated steel plate is usually called a color coated steel plate. Because the coating is carried out before the steel plate is formed and processed, it…

What is carbon steel made of

Related Recommendation carbon steel (carbon steel) is a class of carbon content higher than 0.02% less than 2% (higher than 2% is called cast iron, less than 0.02% is called wrought iron), and few other elements of steel, is also the highest production of metal materials, relatively high other components (excluding impurities) steel called alloy steel. It is usually used on metal parts that require strength, hardness and wear resistance, such as cutting tools, steel cables, piano wires, springs and tools, etc., after the processing is formed, the parts usually need to be treated and tempered.
