1992年9月3日至5日由船舶总公司物资局、冶金部军工办、海装舰艇部联合主持通过了“新一代潜艇用VHD402钢试验工艺模型”科研鉴定,这标志着VHD402钢研制工作进入新的阶段。 在VHD402钢的研制过程中,完成了从试验室到工程性模拟小试样和大型试样及模拟结构建造等全面系统、深入细致的研究工作。洛阳船舶材料研究所是联合课题组组长单位之一,完成了上万个试样的试验,获得了几万个科研数据,解决了强度
From September 3 to September 5, 1992, the research and identification of “VHD402 Steel Test Process Model for a New Generation of Submarines” jointly presided over by the Materials Administration of the Shipping Corporation, the Military Administration of the Ministry of Metallurgy and the Marine Department of the Shipbuilding Department marked the development of the VHD402 steel Into a new stage. In VHD402 steel research and development process, completed from the laboratory to engineering simulation of small samples and large-scale construction of samples and simulation structures, comprehensive and systematic, in-depth and meticulous research. Luoyang Ship Materials Research Institute is a joint task force leader unit, completed the test of tens of thousands of samples, obtained tens of thousands of scientific research data to solve the intensity
