| Common Name | UNS # | Forms Available | C | Cr | Ni | Mo | Ti | Other | Typical Applications |
|---|---|---|---|---|---|---|---|---|---|
| 409……………….. | S40900 | Sheet & Coil ……………………….. | 0.02 | 11.5 | – | – | 0.25 | – | Heat resistant steel, easily formed and welded. Mainly used for automotive exhausts or welded applications where superior performance to galvanised steel is required. |
| 446 | S44600 | Tube & Pipe | 0.08 | 26 | – | – | – | – | Used for severe heat resistant applications up to 1200°C. In recuperators, highly resistant to sulphidation and oil ash corrosion. |
| 430 | S43000 | Sheet, Coil, Plate & Bars | 0.06 | 17 | – | – | – | – | Interior architectural component, stove and automotive trim. Welds tend to be brittle. |
| 444 | S44400 | Sheet & Coil | 0.02 | 18.5 | – | 2 | 0.4 | – | Heat exchanger and hot water tanks and in chloride containing waters. Not prone to chloride stress corrosion – superior resistance to pitting, crevice and intergranular corrosion. Possesses excellent deep drawing properties. |
| 3CR12 (1.4003) | S41050 | Sheet/Plate & Pipe | 0.02 | 11.5 | 0.4 | – | – | – | Good corrosion resistance and readily weldable it provides a cost effective choice for many structural applications where mild or low alloyed steels require regular repair or replacement. |
