Rupal Metals stands out as a top manufacturer and supplier of Stainless Steel 416 Hex Bars in Delhi, India. They specialize in precision-engineered stainless steel products that are celebrated for their excellent machinability and decent corrosion resistance. Stainless Steel 416 is a martensitic stainless steel that has been enhanced with sulfur to boost its machinability while maintaining its strength. Rupal Metals offers SS 416 hex bars in a variety of sizes and finishes, making them perfect for crafting high-precision components that demand strong mechanical properties and easy fabrication. These hex bars find their place in the automotive, machinery, and general engineering sectors, where intricate machining and a good surface finish are key.
Stainless Steel 416 Hex Bars generally consist of Chromium (12–14%), Carbon (up to 0.15%), and sulfur (around 0.15%) to enhance machinability, along with Manganese and Silicon. This alloy boasts a tensile strength ranging from 550–760 MPa, yield strength between 275–450 MPa, and hardness levels of 30–35 HRC when heat-treated. It’s magnetic and offers moderate corrosion resistance, making it suitable for non-aggressive environments. The addition of sulfur aids in chip formation and minimizes tool wear during machining, making SS 416 a great choice for precision components that require tight tolerances and a superb surface finish.

Stainless Steel 416 Hex Bars are widely utilized in applications that demand excellent machinability along with moderate corrosion resistance. You’ll often find them in shafts, gears, valves, fasteners, and fittings across the automotive, pump, and machinery industries. The hexagonal shape makes them easy to handle and allows for effective torque application during assembly. SS 416 is particularly popular for creating complex machined parts like screws, bolts, and detailed components where surface finish and dimensional accuracy are vital. It’s also commonly used in food processing, electrical equipment, and instrumentation sectors where moderate corrosion resistance is essential.
SS 416 contains higher sulfur content for improved machinability, but this reduces its corrosion resistance compared to other stainless steel grades like SS 304 or SS 316. The sulfur content interferes with the formation of a protective oxide layer, making SS 416 more susceptible to corrosion in aggressive environments.
SS 416 hex bars are commonly used in the aerospace, automotive, and manufacturing industries. Their primary applications include shafts, valves, pump components, and fasteners. Due to their excellent machinability, they are ideal for producing precise parts in high-volume machining environments, especially where moderate corrosion resistance is required.
