Type 410 is a martensitic stainless steel which is magnetic, resists corrosion in mild environents and has fairly good ductility.  410 pipe is used where abrasion and wear resistance is needed, combined with fair resistance to general corrosion and oxidation.

General Properties

Alloy 410 (UNS S41000) is a 12% chromium martensitic stainless steel plate that can be heat treated to obtain a wide range of mechanical properties. The alloy has good corrosion resistance along with high strength and hardness. In the annealed condition, 410 stainless steel plate is ductile and may be formed. It remains magnetic in both the annealed and heat treated conditions.

Corrosion Resistance

Alloy 410 stainless steel plate is resistant to atmospheric conditions, water and some chemicals. It can be used in environments containing weak or diluted acetic acid, naptha, nitric acid and sulfuric acid. The alloy is also resistant to acids contained in foods.

410 stainless steel plate can also be used in slightly chlorinated and desaereted water. It performs well in oil and gas applications where desaereted and low hydrogen sulfide exist. However, the alloy is prone to chloride attack, particularly in oxidizing conditions.

410 stainless steel plate stainless steel plate operates well in environments requiring moderate corrosion resistance and high mechanical properties.

Fabrication Data

Heat Treatment

Annealing – Heat slowly to 1500 – 1650°F (816 – 899°C), cool to 1100oF (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
Stress Relieving – Heat to 300 – 800°F (149 – 427°C) for 1 to 2 hours, air cool
Tempering – Heat to 1100 – 1400°F (593 – 760°C) for 1 to 4 hours, air cool

Cold Forming

The alloy can be cold worked with moderate forming in the annealed condition.

Hot Forming

It is typically done in the 1382 – 2102°F (750 – 1150°C) range followed by air cooling. For smaller plate deformation such as bending, preheating should be done in the 212 – 572°F (100 – 300°C) temperature range. If a plate undergoes substantial deformation it should undergo a re-anneal or stress-relieving treatment at about 1202°F (650°C).

Machining

Alloy 410 stainless steel plate is best machined in the annealed condition at surface speeds of 60 – 80 feet (18.3 – 24.4m) per minute. Post machining decontamination and passivation are recommended.

Welding

Alloy 410 stainless steel plate is best machined in the annealed condition at surface speeds of 60 – 80 feet (18.3 – 24.4m) perDue to its martensitic structure, Alloy 410 stainless steel plate has limited weldability because of its hardenability. A post-weld heat treatment should be considered to assure the attainment of the required properties. When weld filler is needed, AWS E/ER 410, 410 NiMo and 309L are the most widely specified.minute. Post machining decontamination and passivation are recommended.
