INTRODUCTION
Alloy 410 is the basic, general purpose martensitic stainless steel that is
used for highly stressed parts and provides good corrosion
resistance plus high strength and hardness. Alloy 410 contains a
minimum of 11.5% chromium which is just sufficient enough to
demonstrate corrosion resistance properties in mild atmospheres,
steam, and many mild chemical environments. It is a general purpose
grade that is often supplied in the hardened but still machineable
condition for applications where high strength and moderate heat
and corrosion resistance are required. Alloy 410 displays maximum
corrosion resistance when it’s been hardened, tempered, and then
polished.
Alloy 410 HT is the basic, general purpose, heat treated version of Type 410.
It used for general purpose, where corrosion is not severe.
Alloy 410S is a low carbon, non–hardening modification of Alloy 410 and
contains 12% chromium martensitic stainless steel. The low carbon
and a small alloy addition minimize austenite formation at high
temperatures which restricts the alloys ability to harden. 410S
remains soft and ductile even when rapidly cooled from above the
critical temperature. This non-hardening characteristic helps
prevent cracking when the alloy is exposed to high temperatures or
welded. 410S is completely ferritic in the annealed condition. It
exhibits adequate corrosion resistance similar to 410 and good
oxidation resistance.
APPLICATIONS
Applications requiring moderate corrosion resistance and high
mechanical properties are ideal for Alloy 410/ 410HT. Examples of applications that frequently used Alloy 410/ 410HT
include:
- Cutlery
- Steam and gas turbine blades
- Kitchen utensils
- Bolts, nuts, screws
- Pump and valve parts and shafts
- Mine ladder rugs
- Dental and surgical instruments
- Nozzles
- Hardened steel balls and seats for oil well pumps
Examples of applications that frequently used Alloy 410S include:
- Petroleum Refining and Petrochemical Processing
- Columns
- Distillation trays
- Heat exchangers
- Towers
- Ore Processing
- Thermal Processing
- Annealing boxes
- Partitions
- Quenching racks
- Gate valves
- Press plates

Processing of 410S
Heat Treatment
The alloy can not be hardened by heat treatment. It is annealed
between 1600 – 1650°F (871 – 899°C), and then air cooled to relieve
cold working stresses. 410S should not be exposed to temperatures
above 2000°F (1093°C), due to embrittlement. If large grains are
found after annealing mildly cold-worked material, the annealing
temperature should be decreased to 1200 – 1350°F (649 – 732°C).
Welding
410S is generally considered to be weldable by the common fusion
and resistance techniques. Special attention should be given to
avoid brittle weld fractures during fabrication; this includes
minimizing discontinuities, maintaining low weld heat input, and
occasionally warming the part somewhat before forming. 410S is
generally considered to have slightly poorer weldability than the
most common ferritic stainless steel grade 409. A major difference
can be attributed to the addition of alloy, to control hardening
which results in the need for higher heat input during welding.
