Applications
Grade 410 stainless steel is commonly used for applications requiring good strength, toughness and reasonable corrosion. These characteristics make it suitable for applications and components such as gas and steam turbine parts, pumps, fasteners, studs, valve components and kitchen utensils.

Corrosion Resistance
410 stainless steel offers good corrosion resistance to atmospheric corrosion, water and some chemicals. Its optimum corrosion resistance is in the hardened and tempered condition and is best achieved by allowing oxygen to circulate freely on the surface which will form an oxide film which protects the steel. Keeping the surface free of scale and foreign particles improves corrosion resistance which makes 410 stainless suitable to exposure to chlorides in daily activities such as food and sports environments. Finished components should be passivated. For best corrosion resistance properties 410 stainless steel is mostly supplied in the ‘R’ condition as 410S21R
Annealing
Heat slowly to 820-900°C, hold until temperature is uniform through the steel. Soak well and allow to cool in the furnace.
Forging
Pre heat carefully, then raise temperature to 1100-1200°C, hold until temperature is uniform through the steel. Do not forge below 900°C. After forging stainless steel 410 grade, cool slowly in a furnace or warm ashes.
Hardening
Heat slowly to 950-1020°C and hold until the temperature is uniform throughout the steel. After adequate soaking quench in oil or air cool. Temper as soon as tools are hand warm.
Tampering
Heat carefully to a suitable tempering temperature. Soak as required and then allow to cool in air. Tempering between 600-700°C will achieve ‘R’ condition. 410 stainless steel can be tempered at lower temperatures to achieve higher tensile strengths but with lower impact properties. Tempering between 400-580°C is not advised as tempering within this range will seriously reduce impact properties and corrosion resistance.
