Manufacturer, Supplier & Exporter of Stainless Steel 410 Round Bar

Stainless Steel 410 Round Bar is a widely used martensitic stainless steel grade that offers a combination of moderate corrosion resistance, high strength, and excellent wear resistance. Riddhi Siddhi Impex, a leading manufacturer and supplier in India, provides SS 410 round bars with consistent quality and reliability. With decades of experience in the steel industry, the company has positioned itself as a key supplier of stainless steel products, catering to industries ranging from automotive, aerospace, chemical processing, construction, and engineering applications. Their SS 410 round bars are manufactured to meet strict quality standards and are supplied across India to both metro cities and industrial hubs...

The chemical composition of SS 410 Round Bar defines its unique properties. Typically, it contains 11.5–13.5% chromium, which provides corrosion resistance, along with ≤0.15% carbon for hardness. Other elements include manganese (≤1%), silicon (≤1%), phosphorus (≤0.04%), and sulfur (≤0.03%). This composition makes SS 410 a hardenable stainless steel, meaning it can be heat-treated to achieve higher strength and wear resistance. The balance of chromium and carbon ensures that while the steel maintains reasonable corrosion resistance, it also offers mechanical strength suitable for demanding industrial applications..

The mechanical properties of SS 410 round bars vary depending on their condition (annealed, hardened, or tempered). In the annealed state, the tensile strength is around 480–520 MPa, yield strength approximately 275 MPa, and elongation around 16–25%. The Brinell hardness in the annealed condition is generally up to 217 HB. After heat treatment, the hardness can significantly increase, making it suitable for components subject to wear and impact. With a density of 7.74 g/cm³, this material provides a durable and reliable solution for both structural and mechanical applications..

SS 410 round bar is appreciated for several unique features. It is magnetic, which can be useful in certain applications, and offers good machinability in the annealed condition, allowing ease of fabrication. Its hardenability means it can be heat-treated to increase strength and wear resistance. Additionally, SS 410 is suitable for moderate corrosion environments, making it ideal for industrial components, kitchen utensils, fasteners, and machinery parts. The combination of strength, durability, and moderate corrosion resistance makes it versatile across multiple sectors..

The applications of Stainless Steel 410 Round Bar are broad and diverse. It is extensively used for valve components, pump shafts, gears, and turbine blades due to its strength and wear resistance. In the kitchenware and cutlery industry, it is used to make blades, knives, and utensils that require polishable surfaces and moderate corrosion resistance. It is also found in automotive components, industrial fasteners, and mechanical parts exposed to moderate environmental conditions. Its ability to be hardened and tempered makes it highly adaptable for both functional and structural applications..
