410S is the low carbon variant and it is ferritic.

Because if you review ASME/ASTM SA/A 240 material specification, the 410S maximum carbon content is 0.08% by mass, the 410 range is 0.08% to 0.15% by mass. However, ASME B&PV Code, identifies the 410S as ferritic, based on a P-No 7 grouping designation, whereas, 410 is a martensitic grade and is under P-No 6 grouping.

Even though the carbon in 410S is too low to Q&T like a martenstitic you still need to treat is as one when you well to minimize the risk of cracking.
This is called being careful.

This is one definition given for martensitic grades in ASTM A959-11.
"3.1.4 martensitic grade, n—metallurgical term meaning that
the material is capable of being produced in a distorted
body-centered cubic structure by conventional heat treating
and quenching, and that the quenched structure is capable of
conventional tempering. Martensitic grades are delivered in the
annealed (ferritic) condition or the hardened and tempered
(martensitic) condition."
So it may be ferritic or martensitic depnding on the heat treatment it undergoes, as per our demand??

With 410S if you quench it you may form a little bit of lean martensite, but it isn't very hardenable, not enough C.

In time you will come to loathe both these alloys.
