1.4310 / X10CrNi18-8

Properties
1.4310 is an austenitic Cr-Ni steel with good corrosion resistance (PREN ≈ 18). The formation of chromium-depleted areas as a result of additional heat treatment beyond the as-supplied condition creates a risk of intergranular corrosion. Polishing the surface achieves the best possible corrosion resistance.
During cold forming, the material work-hardens through the transformation of metastable austenite into martensite; this reduces its resistance to corrosion.

Delivery Condition
- solution annealed (+AT)

Application Area
Used in the cold-formed state in spring components with operating temperatures of up to 300 °C.

Typical Applications
- Spring components
- Clamping springs (electrical industry)
- Food industry
- Stamped and deep-drawn parts

Grade no.: 1.4310
Grade name: AISI 301, X10CrNi18-8
