Martensitic stainless steels are iron-chromium alloys that contain
from 10% to 18% chromium
and can be hardened by heat treatment to high strength levels.
Type 410 stainless steel is the basic alloy in this grouping.
The martensitic types are the lowest in their ability to withstand
corrosion.
Adding more carbon to the basic martensitic alloy increases
hardness.
But, as carbon is increased, chromium content is also increased to as high as 18% to maintain
no less than 10% free chromium for corrosion resistance.
Other modified martensitic alloys contain additional elements, such
as sulfur or selenium.
typical Free machinging grades ( EN 1.4005, 416 and EN 1.4029, 420F
).
Martensitic varieties find major applications in products that must
resist atmospheric oxidation,
mildly corrosive chemicals, and wet or dry corrosion environments
found in steam and gas turbine parts,
bearings, and cutlery. The martensitic types are magnetic in all
conditions.
Martensitic Summary:
- Hardenable by heat treatment
- Magnetic
- High strength
- Moderate resistance to corrosion
- Contains no nickel

| Grade | Description |
| 416, S41600, 1.4005, X12CrS13 | 416 stainless grade combines the following characteristics: - Basic corrosion resistance lower than grade 410 due to sulphur
- Moderate strength and toughness
- Excellent machinability index approximately 90 compared to 100 for
free cutting mild steel
416 is the preferred free machining grade where higher strength
than 303 is required. It is essentially grade 410 (1.4006) with sulphur for free
machining. It is ideal for high throughput, intricate components.
Applications include: Shafts, axles, gears, valves, fasteners, golf club heads, sensors,
precision machined components, gun barrels, washing machine parts,
dowel pins, clamps, collars. |
