410 (S41000) | BYBOLT

What is 410 stainless steel and its applications?

410 stainless steel (UNS S41000) is a hardenable martensitic chromium steel. It is used for mechanical components that need a combination of strength, hardness and corrosion resistance in environments less aggressive than those requiring highly alloyed stainless grades.

Industrial machinery: Loaded components with a specified quenched-and-tempered condition.
Valve equipment: Mechanical parts selected for the actual process environment.
General engineering: Components requiring a controlled balance of hardness and ductility.

Engineering Application & Selection Guide

Quenching develops a martensitic structure and tempering adjusts its mechanical properties. The heat-treatment condition is therefore essential: annealed 410 and quenched-and-tempered 410 are not interchangeable strength descriptions.

410 hex bolts — For loaded joints, state the required hardness, tensile properties and any toughness requirement.
410 stud bolts — For valve connections, confirm corrosion compatibility before selecting a condition for strength.
410 custom fasteners — For a locating or wear feature, separate its hardness requirement from the strength and ductility required at the thread.

Compare 431 when toughness and corrosion resistance justify another martensitic grade, or 17-4 PH for a different strengthening route. Require traceable heat-treatment results; a nominal grade or polished surface does not establish finished-part performance.

Procurement and application guide

Specify the material and final condition

Specify hardness, heat treatment and section size.

Material forms in the technical reference: Plate · Sheet · Strip · Bar.

Define the finished-part acceptance

Include the material or bolting specification, required final condition, dimensions and quantity. State the service medium, temperature and loading where known. Agree the required tests, inspection coverage and acceptance criteria for the finished part.
