410 stainless steel is a hardenable martensitic stainless steel alloy.
Unlike austenitic grades it can be heat treated ("quench and temper") to
generate high strength with good ductility. 410 alloy is required when
strength, hardness and wear resistance is required with some corrosion
resistance. Due to the hardening capabilities of this steel,
other properties and the resulting performance of this material are
somewhat compromised. The alloy can only effectively be used in mildly
corrosive environments. The operating temperature range is limited a) a
loss of strength by over tempering at elevated temperatures and b) a
loss of ductility at sub-zero temperatures.Type 410 is officially a
stainless steel but characteristically the material is actually a
compromise of high carbon steel alloy (which promotes wear resistance)
with chromium stainless steel (which promotes corrosion resistance).
This steel is ideal for use in the manufacture of highly stressed parts
found in a variety of industries including petrochemical, automotive
and power generation.

Background of 410 Stainless Steel Pipes and Tubes
Grade 410 is the basic martensitic stainless steel; like most
non-stainless steels it can be hardened by a "quench-and-temper" heat
treatment. It contains a minimum of 11.5 per cent chromium, just
sufficient to give corrosion resistance properties. It achieves maximum
corrosion resistance when it has been hardened and tempered and then
polished. Grade 410 is a general purpose grade often supplied in the
hardened, but still machinable condition, for applications where high
strength and moderate heat and corrosion resistance are required.
Martensitic stainless steels are optimised for high hardness, and other
properties are to some degree compromised. Fabrication must be by
methods that allow for poor weldability and usually the need for a final
heat treatment. Corrosion resistance of the martensitic grades is lower
than that of the common austenitic grades, and their useful operating
temperature range is limited by their loss of ductility at sub-zero
temperatures and loss of strength by over-tempering at elevated
temperatures. Composition of 410 Stainless Steel Pipes and Tubes Typical compositional ranges for grade 410 stainless steels are given in table 1. Table 1. Composition ranges for 410 grade stainless steel
