SMM News: according to Jiuquan Iron and Steel Co., Ltd., high carbon martensitic steel as an important steel grade for structural adjustment of stainless steel products of Jiuquan Iron and Steel Co., Ltd., because of its poor welding performance, it is difficult to produce, so other steel mills basically do not have the ability to produce. The stainless steel branch of Jiuquan Iron and Steel Co., Ltd. continuously optimized the production process by using the existing equipment. On August 5, 2019, the chromium steel pickling line of the stainless steel branch of Jiuquan Iron and Steel Company realized the batch and stable production of high carbon martensite (50Cr15MoV) steel.
According to reports, due to the composition characteristics of high carbon martensitic steel, such as unstable welding quality and difficult surface treatment. The production efficiency is low and the fault incidence is high in the continuous line. Through continuous testing and improvement, the technicians of Jiugang stainless Steel Branch and the technical staff of Jiuquan Iron and Steel Research Institute have realized the mass production of the steel, with a total of 42 volumes and 636.2 tons. The qualified rate was 100%. The whole production process "zero" failure.
Jiugang said that the chromium steel pickling line smooth mass production of high carbon martensite (50Cr15MoV) steel, breaking through the Jiugang stainless steel branch product structure adjustment constraints, for Jiugang stainless steel "improve quality and efficiency" work contribution.
