A36 HRS vs 1018 CRS - Practical Machinist

Apr 28, 2011 · ASTM A36 is the minimum strength designation - 36 KSI This is the cheapest structural grade and what most rebar, chanels, angles, etc are made from. The 70 KSI for AISI 1018 is an average strength rating and most of the added strength does come from being cold worked.A36 Steel Properties at High Temperatures HunkerAccording to a Federal Emergency Management Agency (FEMA) study, A36, while an excellent structural material, loses much of its strength, rigidity and tensile strength at high temperatures. According to graphs in the FEMA study, A36 has a maximum strain measurement of more than 70 kilograms per square inch at 200 degrees Celsius.

The steel is first heated up to a specific temperature, then cooled by air. Depending on the type of steel, normalizing temperatures usually range from 810 degrees Celsius to 930 degrees Celsius.Metallography of SteelsThe thermal grooves reveal the austenite grain boundary structure. The photographs are taken using ordinary reflected light microscopy. Here the sample is transformed to allotriomorphic ferrite to avoid surface relief effects.
