摘要
Abstract
The paper introduces application of Q550D low-alloy high-strength steel in large-scale tower crane,focusing on the chemical composition and mechanical performance of Q550D steel,analyzes the manufacturing and welding technolo-gies of Q550D forging pieces,and puts forward corresponding solutions for problem existing in forging and welding,provi-ding important reference value for application of such low-alloy high-strength steel in large-scale tower crane.关键词
