General-purpose stainless steels offer good corrosion and heat resistance for a wide range of operating conditions. This is symptomatic of passivation, a phenomenon where chromium (Cr) within a metal lattice reacts with oxygen (O2) in the atmosphere or moisture. A microscopic thin film forms at the interface between the metal and the environment, preventing further corrosion by inhibiting oxygen diffusion.
Often, stainless grades must be engineered for a compromise between maximum corrosion resistance and high strength mechanical properties. Type 410 stainless steel is the result of such a compromise. In this blog post, Masteel explores the properties and applications of 410 stainless steel in more depth.
Outlining 410 Stainless Steel
Like many stainless grades, the primary alloying element in 410 stainless steel is chromium. It accounts for approximately 12% of the alloy’s chemical composition and imparts mild corrosion-resistant properties. Other alloying elements include carbon (C), manganese (Mn), and nickel (Ni). The carbon content of 410 stainless steel can vary from 0.08 – 0.15%, which is characteristic of a wear-resistant high carbon steel alloy.
Chromium and carbon are crucial to the unique characteristics of 410 stainless steel. It can simultaneously be considered an inoxidizable stainless grade and a high carbon steel alloy, benefiting from good corrosion and wear-resistance. As mentioned, this is intended as a compromise between the two mechanical properties. 410 stainless steel is incapable of competing with the likes of 304 stainless in terms of resistance to concentrated acid solutions, for example.
However, this ideal chemical composition means that 410 stainless steel can be hardened via heat treatment to achieve high strength (450 MPa) with good ductility. This makes it ideal for manufacturing highly-stressed parts.
Applications of 410 Stainless Steel
With a decent combination of mechanical properties and moderate corrosion resistance, 410 stainless steel is ideal for a range of applications with mildly corrosive conditions. It is readily employed for use in the petrochemical sector for petroleum fracturing structures and gas turbines. Automotive valves and pumps are also routinely manufactured using 410 stainless steel.
