Multinox Inc. is a manufacturer, supplier, and stockist of Stainless Steel 416 Rings.
Stainless Steel 416 Rings are also widely recognised as UNS S41600/ WNR 1.4005, a martensitic chromium alloy containing chromium (about 12-14%), with a controlled addition of sulfur, manganese, and silicon that stabilises the material. This alloy ring shows higher machinability than most other stainless steels due to its sulfur content, achieving a machinability rating of approximately 85% relative to free-machining carbon steel, while also providing good corrosion resistance across mild to moderate environments. 416 alloy rings play a crucial role across fresh water, dry air, and some organic environments.



Stainless Steel 416 Rings are a super machinable grade alloy with excellent strength and outstanding machining benefits. These rings are generally considered ideal choices when applications such as automotive components, pumps, valves, gear components, shafts, and fasteners require extensive and complex machining. The combination of high strength, hardenability, and corrosion resistance makes 416 alloy rings withstand different environmental conditions. 416 rings offer exceptional machinability for quick production with reduced tooling wear. They present high hardenability and wear resistance post heat treatment. Mild to moderate resistance also gives peace of mind for general atmospheres.
These 416 rings are manufactured in various forms, including forged rings, rolled rings, machined rings, plate-cut rings, etc., matching your exact preference. Each ring undergoes careful inspection for quality control and dimensional accuracy before proceeding through destructive and non-destructive testing, including a Material Test Report (MTR), to ensure complete compatibility and reliability for the clients. Standard available sizes for 416 rings include outer diameters ranging from 145 to 3000 mm, face heights of up to 49 inches, and individual weights of up to 60,000 lbs, based on specific industrial operations.
Multinox Inc. offers 416 rings in annealed, hardened, and tempered conditions to match your exact application demands. To achieve higher strength and robust build quality, they can also be heat treated to reach peak quality. They are constructed using open-die, closed-die forging, and seamless rolling methods. General applications for 416 rings include pump shafts, valve trim, gears, lead screws, nuts and bolts, and other components that require complex procedures and high numbers of machining while maintaining good strength.
