Yes. As a martensitic stainless steel it is magnetic in all conditions.

SS410 can be hardened and is stronger and more wear-resistant; SS304 resists corrosion much better and cannot be hardened. Choose by whether strength or corrosion matters more.

It resists mild corrosion, but less than 304 or 316, and can rust in wet or salty conditions, especially if poorly finished.

SS410 stainless steel

Also called: AISI 410, 1.4006, X12Cr13, SUS410, martensitic stainless, 410 stainless

SS410 is a martensitic stainless steel with about 12% chromium. Unlike 304, it can be hardened by heat treatment and is magnetic, but its corrosion resistance is lower. It is used for valve and pump parts, shafts, fasteners and cutting tools.

Quick facts

Type: Martensitic stainless steel
Chromium: About 11.5–13.5%
Hardenable?: Yes, by heat treatment
Magnetic?: Yes
Corrosion resistance: Moderate: lower than 304
Typical hardened hardness: Roughly 35–45 HRC depending on tempering

Equivalent grades

Standard	Grade
AISI / ASTM	410 (UNS S41000)
EN / DIN	1.4006 (X12Cr13)
JIS	SUS410

Typical chemical composition

Element	%
Carbon (C)	0.08–0.15
Chromium (Cr)	11.5–13.5
Manganese (Mn)	1.0 max
Silicon (Si)	1.0 max

Heat treatment

Hardening: about 950–1010 °C, quench in oil or air
Tempering sets the final hardness and toughness; avoid the range around 400–550 °C, where toughness and corrosion resistance suffer
Annealed for machining, then hardened

Typical uses

Valve trims, stems and seats
Pump shafts and impellers
Fasteners and springs
Steam and gas turbine parts
Cutlery and surgical tools (420 has more carbon for sharper edges)

Questions

Is SS410 magnetic?: Yes. As a martensitic stainless steel it is magnetic in all conditions.
SS410 or SS304?: SS410 can be hardened and is stronger and more wear-resistant; SS304 resists corrosion much better and cannot be hardened. Choose by whether strength or corrosion matters more.
Does SS410 rust?: It resists mild corrosion, but less than 304 or 316, and can rust in wet or salty conditions, especially if poorly finished.
