UH446 stainless steel pipe ~ price stainless steel rod

<
It contains chromium, nickel, molybdenum, titanium, nitrogen and other elements. It has good comprehensive performance and can withstand corrosion from various media. Commonly used grades of austenitic stainless steel include: r steel, marked in the steel number. This type of steel contains a large amount of R and R, which makes the steel in an austenitic state at room temperature. This type of steel has good plasticity, toughness, weldability and corrosion resistance, and has good corrosion resistance in both oxidizing and reducing media. It is used to make acid-resistant equipment, such as corrosion-resistant containers and equipment lining pipelines, and nitric acid-resistant equipment parts. wait. Austenitic stainless steel generally adopts solution treatment, that is, the steel is heated to ~℃ and then water-cooled to obtain a single-phase austenite structure. < >Austenitic Ferrite
> It has the advantages of both austenitic and ferritic stainless steel and has superplasticity. Stainless steel with approximately half austenite and ferrite structures each. In the case of lower content, the r content is ~ and the r content is ~. Some steels also contain alloying elements such as b and b. This type of steel has the characteristics of both austenitic and ferritic stainless steel. Compared with ferrite, it has higher plastic toughness, no room temperature brittleness, significantly improved intergranular corrosion resistance and welding performance, while maintaining ferrite The solid stainless steel has the characteristics of ℃ brittleness and high thermal conductivity, and super plasticity. Compared with austenitic stainless steel, it has high strength and significantly improved resistance to intergranular corrosion and chloride stress corrosion. Duplex stainless steel has excellent pitting corrosion resistance and is also a nickel-saving stainless steel.
>Martensitic stainless steel has high strength, but poor plasticity and weldability. Commonly used grades of martensitic stainless steel include: Because of its high carbon content, it has high strength, hardness and wear resistance, but slightly poor corrosion resistance. It is used for some parts that require high mechanical properties and average corrosion resistance. On the market, such as spring turbine blade hydraulic press valve, etc. This type of steel is used after quenching and tempering treatment.
