Properties Of Hot Rolled Strip Obtained By Calculation

The layout of the hot strip mill of voestalpine Stahl GmbH is shown in Fig. 1. Slabs are heated to rolling temperature in the reheating furnace, subsequently descaled and rolled in the roughing stand to the transfer bar thickness and - after a second descaling step - rolled to the final thickness, cooled on the run out table and coiled.

Metals Alloys for HighTemperature Services

Metals Alloys For Hightemperature Services

Therefore, its vital that you check the technical data describing the properties of the metal in question before deciding if its the alloy for you. Quite often the temperature is the first, and in some cases, only data point that most people look at when basing their choice of alloy. This is the wrong thing to do.
