410 is a martensitic stainless steel that provides high strength and hardness with moderate corrosion resistance.

410L 1.4003 is a low-chromium structural ferritic stainless steel. Its corrosion resistance is limited in applications with increased corrosiveness.

410S (UNS S41008) is a low carbon, non–hardening modification of Alloy 410 (UNS S41000) the general purpose 12% chromium martensitic stainless steel.

Typical applications

Railroad and road vehicles

Shipping containers

Industrial applications

Heat Treatments of grade 410 stainless steels

Annealing: Heat slowly to 1500-1650°F (816-899°C), cool to 1100°F (593°C) in furnace, air cool.

Process Annealing: Heat to 1350-1450°F (732-788°C), air cool.

Hardening: Heat to 1700-1850°F (927 – 1010°C), air cool or oil quench.

Follow by stress-relief or temper.

High Temperature Tempering: Heat to 1100 – 1400°F (593 – 760°C) for 1 to 4 hours, air cool.

Low Temperature Tempering: Heat to 300 – 500°F (150 – 260°C) for 0.5 to 1 hours, air cool.

Corrosion Resistance of grade 410 stainless steels

AISI Type 410 provides good corrosion resistance to air, water and some chemicals. It shows satisfactory resistance to ammonia, nitric acid, concentrated sulfuric acid, dilute acetic acid and naptha. Resistance to food acids is good. Maximum corrosion resistance is achieved in the fully hardened condition.>AK Steel Type 410 provides good corrosion resistance to air, water and some chemicals. It shows satisfactory resistance to nitric acid, concentrated sulfuric acid, dilute acetic acid and naptha. Resistance to food acids is good.

Heat Resistance of grade 410 stainless steels

Grade 410 steels have good scaling resistance at temperatures of up to 650 °C. However, the mechanical properties of the material will tend to reduce at temperatures ranging from 400 to 580 °C.

Forming

The formability of Moda 410L/4003 is comparable to many high-quality carbon steels. It is well suited for standard cold forming operations like bending, flanging, and drawing, but has limited stretch formability. When performing demanding forming operations, it might be necessary to perform drawing in several steps with intermediate annealing.

Machining

Moda 410L/4003 is relatively easy to machine. Compared to austenitic grades, it has lower tendency to form edges, which gives a larger machining window. Since the machinability is comparable to that of structural carbon steels, the same recommendations regarding choice of tool, cutting speed, and cutting feed can be used.

Welding

Moda 410L/4003 has good weldability and can be welded using the common fusion and resistance welding methods. Conventional welding methods like MMA, MIG, MAG, TIG, SAW, LBW, or RSW – except gas welding – are applicable. Austenitic 19 9 L (308L) or 13 Cr filler metals can be used.
