6. Corrosion Resistance

00Cr18Ni18Mo5 stainless steel has good corrosion resistance, especially in oxidizing and reducing conditions. In addition, it also has good stress corrosion resistance at high temperatures.

00Cr18Ni18Mo5 austenitic stainless steel has excellent overall performance, easy processing and good compatibility with other materials. It is a heat-resistant steel and is widely used in the production of storage tanks, equipment for the industries of chemical, oil and food, and welding components.

00Cr18Ni18Mo5 austenitic stainless steel is a kind of ultra-low carbon high alloy stainless steel with excellent process performance and corrosion resistance. Its corrosion resistance and process performance are comparable to or higher than the 0Cr18Ni18Mo5Ti, the grade of material by adding Ti. The steel of the 00Cr18Ni18Mo5 has high plasticity, toughness and weldability, and is suitable for the manufacture of components and parts requiring good process performance and corrosion resistance.

The steel of this grade is mainly composed of Cr, Ni and Mo and other alloying elements. Among them, Cr and Ni are the main alloying elements that ensure the corrosion resistance of this kind of steel, and Mo is an important alloying element to strengthen the steel structure and inhibit sensitization resistance. These three alloying elements determine the superior process performance and corrosion resistance of this kind of steel.

00Cr18Ni18Mo5 austenitic stainless steel has good process performance, which can be cold bent, hot bending and pressing forming and other complicated processing such as welding. The maximum bending radius of cold bending is 4-5 times the diameter of the steel bar. Due to its high flexibility, it has been widely used in the production of corrosion-resistant components and parts in thin-walled structures. In addition, its welding performance is also good, and it is suitable for welding by all welding methods.

The corrosion resistance of 00Cr18Ni18Mo5 austenitic stainless steel is very outstanding. In the atmosphere, water, food and other media, it has higher pitting and crevice corrosion resistance than conventional steel; in the acidic medium of sulfuric acid and hydrochloric acid, it has higher chlorine ion corrosion resistance; in the environment of oxidizing medium, its oxidation resistance is also very good.

The 00Cr18Ni18Mo5 austenitic stainless steel is a kind of very high alloy stainless steel. It has outstanding process performance and excellent corrosion resistance, which is suitable for the production of thin-walled components and parts for corrosion environment, food industry, chemical industry and equipment.
