First heat treating tests on the Ovmat 9


Mat. No. DIN EN AISI Type
1.0570 S355J2+C ST52-3K
Structural grade carbon steel

Tests 180511

This low carbon steel is not the best material to test the hardening capabilities of the furnace. Therefore I tried to make some heat treatment tests.

The first part (in the oven on the featured image) was an Tripan toolholder which was messed up. This item was heated up to something about 900°C and quenched in tap water. The result is not that uniform as on the second test.

The second part is the first of a row (the raw pieces can be seen on the left). This one was heated to about 600° C and quenched in oil. It went to a nice dark colour…
