Stainless Steel 418 Forging is an ideal choice for parts requiring higher strength and corrosion resistance. It offers excellent fatigue strength, good weldability, and formability, as well as significant corrosion resistance properties. This forging grade is suitable for many applications in the oil & gas, petrochemical, and power generation industries.
Due to its high chromium content, Stainless Steel 418 Forgings offer excellent oxidation resistance under high temperatures. Its mechanical properties can be improved by cold working or heat treatment to increase hardness and strength, making it a great option for parts that must withstand extreme conditions.
Stainless Steel 418 circles are a type of forging used in numerous industrial applications such as valves, shafts, fasteners, flanges, and more. These circles are available in a variety of sizes and thicknesses to fit any customer’s specific needs. The high chromium content also makes them an excellent choice for parts that require superior corrosion resistance and durability.
At Lint Steels, we specialize in supplying custom Stainless Steel 418 Forgings tailored to meet your exact specifications. Our experienced team is available to help you select the best material and forging grade for your project so that you can get the optimal performance out of your parts.
