| 500 ## - GENERAL NOTE | |
| General note | Heat treatment plays a major role in improving the material properties. With the<br/>addition of cryogenic treatment these properties can be further improved. In this paper heat<br/>treatment is carried out on low carbon low alloy structural steel in two different types of<br/>furnaces conventional box type air furnace and vacuum furnace along with shallow cryogenic<br/>treatment with the purpose to investigate the outcome of shallow cryogenic treatment on the<br/>material properties and to find out which type of furnace is more suitable with shallow<br/>cryogenic treatment. For this purpose, structural steel 30CrMnSiA was selected, and heat<br/>treatment was carried out in conventional box type air furnace (900°C × 40mins) and vacuum<br/>furnaces (900°C × 70mins), shallow cryogenic treatment (-75°C × 125mins) was carried out<br/>after the quenching and before tempering. For the physical properties of the material,<br/>hardness (HRC) was investigated using Brinell hardness tester HBD-62-5AP. Tensile<br/>samples were prepared as per ASTM E8/E8M and investigated using 100kN WAW-100B<br/>Electro-Hydraulic Servo Computer Control Universal Testing Machine. Impact toughness<br/>was measured by using electronic pendulum impact testing machine CBD-300 and specimens<br/>were prepared using ASTM standard E23-12c. Microstructural analysis for grain structure<br/>was carried out using Olympus DSX1000 optical microscope. |
