| Abstract: | This paper describes a study on welding hot crack characteristic of recently-developed complex microalloy highstrength steel P460NL1 through longitudinal adjustable restrainttest. The theoretioal analysis and test result prove that this kind of steel has small tendency to form hot crack |
