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:

RESISTANCE
COMMON PROCESSING
Welding Characteristics
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).
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.
