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:
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. |
