Witryna22 maj 2024 · Abstract: DMR-249A is a low carbon microalloyed high-strength low-alloy (HSLA) steel. While DMR-249A plates of thickness less than 18 mm meet the specified room temperature yield strength (390 MPa) and Charpy impact toughness (78J at −60 °C) in the as-rolled condition, thicker plates require water quenching and tempering. WitrynaDuring the casting cooling process or the forging process, austenitic stainless steel will remain at around 800 °C for some time. During this period, precipitate particle …
