Stainless Steel Wire, Rod, Round Bars EN 10095 1.4742 AISI 442
Stainless heat resistant ferritic chromium steel with aluminium
addition, material EN 10095, 1.4742, DIN X10CrAlSi18
AISI 442, UNS S44200, SEW 470, 1.4742, X10CrAl18, resistant to
scaling in air up to 1000°C
1.4742 is a heat resistant, ferritic stainless steel which is
characterised by its resistance sulphur bearing gasses.
Due to its higher chromium content, material 1.4742 is more
resistant to high temperature oxidation than
1.4724, but is less resistant than 1.4762, which contains even more
chromium.

Typical applications of material 1.4742
bolts, fasteners, high temperature nozzles and jets, furnace
engineers, mechanical parts etc.
Heat treatment
Optimal material properties are realised after annealing by holding
in the temperature range
800 - 860°C, followed by rapid cooling in air or water. In this
condition the following mechanical
properties can be expected when testing in the longitudinal
direction at room temperature:
| Property | Specification | Typical |
| Tensile strength | Rm 500 - 700 | 580 |
| Yield strength | Rp0.2 ≥270 | 370 |
| Elongation | A5 ≥15 | 18 |
| Hardness | HB ≤212 | |
