410 Stainless Steel
Type 410 Stainless Steel sheet and strip is covered by the following specifications:AMS 5504, ASTM A240.
|Carbon||0.08 – 0.15|
|Chromium||11.5 – 13.5|
|Type||Yield Strength 0.2% offset (KSI)||Tensile Strength (KSI)||% Elongation (2" Gauge length)||Hardness Rockwell|
|410 Ann||30 min.||65 min.||20 min.||HRB 96|
Type 410 has reasonably good cold working properties and can be moderately drawn and formed in the annealed condition.
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.
Stress Relieving: Heat at 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.
The martensitic class of stainless steels has limited weldability due to its hardenability. Preheating to 550 °F (260 °C) is generally not required for thin sheet sections of this lower chromium martensitic stainless steel. Post-weld heat treatment should be considered to achieve required properties. This particular alloy is generally considered to have the best weldability of this stainless class. A major difference is the lower carbon content for this alloy which eliminates the need for post-weld heat treating. When a weld filler is needed, AWS E/ER 410, 410 NiMo, and 309L are most often specified. Type 410 is well known in reference literature and more information can be obtained in this way.
