X2CrNiN18-7 is a stainless steel grade developed to resist corrosion in a wide range of environments. It has excellent corrosion resistance in marine and industrial atmospheres, and its low carbon content means that it is suitable for food handling and has good weldability.
X2CrNiN18-7 is highly resistant to staining and pitting, making it ideal for use in applications such as catering, food processing and chemical production. It also provides excellent protection against iodine and chloride pitting so can stand up to aggressive chemicals and salt water. For this reason it is often used for components in harsh areas, such as heat exchangers, instrumentation, valves and pumps.
Due to its strength, X2CrNiN18-7 is also suitable for use in heavily loaded structures and components. It has good formability and doesn’t suffer from stress-corrosion cracking, making it an excellent choice for structural components in corrosive environments. It is also used for pressure vessels, tanks and chemical processing equipment, as it can be welded and brazed without the risk of corrosion.
X2CrNiN18-7 is a ferritic stainless steel which has excellent weldability. When joining material, adequate preheating and post-weld heat treatment are sensible precautions which will enhance the weld, reduce residual stresses and improve the corrosion resistance of the joints.
X2CrNiN18-7 has a wide range of uses due to its excellent corrosion resistance and strength. It is used across many industries, from food processing and catering to construction and engineering applications. It can be used as a component in a wide range of environments, from corrosive marine environments and acidic chemical plants to harsh oil and gas environments. Its low carbon content also allows it to be used for food handling, making it an ideal stainless steel for food and catering industries.
Overall, X2CrNiN18-7 is an excellent stainless steel for use in corrosive and harsh environments. Its good corrosion resistance, strength and weldability make it an excellent choice for components and structures in a wide range of industries, from catering and food processing to engineering and construction. Due to its low carbon content it can also be used for food handling and has good weldability.
