Hemi Metals, located in Hamilton, New Zealand, is a reliable manufacturer and supplier of high-quality Stainless Steel 416 Hex Bars, perfect for precision machining and demanding industrial applications. SS 416 is a free-machining martensitic stainless steel designed to provide excellent machinability, solid mechanical strength, and moderate resistance to corrosion. With a focus on strict dimensional accuracy, sharp hex profiles, and controlled metallurgical quality, these hex bars guarantee high productivity and consistent performance. Hemi Metals caters to various industries, including automotive, industrial machinery, oil & gas, and precision engineering, where accuracy, machining efficiency, and durability are crucial.
Stainless Steel 416 is composed of about 12–14% chromium, with a carefully controlled carbon content and added sulfur to boost machinability. This sulfur enhances cutting performance but does come with a slight reduction in corrosion resistance compared to SS 410. Typically, SS 416 hex bars achieve tensile strength between 500–700 MPa after heat treatment, showcasing good hardness and moderate ductility. The material is magnetic, responds well to hardening and tempering, and maintains excellent dimensional stability during machining, ensuring reliable mechanical performance under load.

Stainless Steel 416 Hex Bars find extensive use in applications that demand superior machinability, solid strength, and moderate corrosion resistance. They are commonly used for high-temperature fasteners, nuts, bolts, studs, valve components, shafts, fittings, and precision-machined parts. In sectors like automotive, oil & gas, and industrial machinery, SS 416 hex bars are essential for high-speed production components and rotating mechanical assemblies. They are also utilized in tooling, couplings, and general engineering fabrications. With their outstanding machinability, mechanical strength, and cost-effectiveness, they are a go-to choice for many applications.
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.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
