Taking advantage of the situation, Hunan s stainless steel industry is discussing "innovation" and seeking "new opportunities" together
On February 26th, the New Year symposium of the Stainless Steel Special Committee of the Hunan Metal Materials Chamber of Commerce was held in Changsha, with the theme of "working together to achieve peak strength". Leaders from processing and trading enterprises in the stainless steel industry in Hunan, as well as representatives from steel mills, gathered together to conduct in-depth discussions on the innovative development of the stainless steel industry.
The stainless steel industry is a strategic and fundamental industry in China. Leveraging the supporting role of stainless steel as a key functional material is of great significance for promoting the development of advanced equipment manufacturing, green and low-carbon energy transformation, and more. Zhang Shunxin, Chairman of the Stainless Steel Special Committee of the Hunan Metal Materials Chamber of Commerce and Chairman of Hunan Shunxin Metal Products Technology Co., Ltd., stated that the stainless steel industry in Hunan must follow the trend, continue to promote digital transformation, closely focus on the implementation of the "three highs and four innovations" strategy in Hunan, focus on the advanced

Consensus reached at the 2024 stainless steel industry chain symposium - stainless steel demand will continue to grow in 2024
On the afternoon of January 23, the Stainless Steel Branch of the China Iron and Steel Industry Association held a symposium and exchange meeting on the 2024 stainless steel industry chain in Beijing. The attending representatives unanimously agreed that the demand for stainless steel will continue to grow in 2024.
At the meeting, Zhang Zhifang, Executive Chairman of the Stainless Steel Branch of the China Iron and Steel Industry Association, introduced the relevant development situation of the stainless steel industry in 2023 and the development direction in 2024. Representatives of stainless steel and upstream and downstream industry associations in the industry chain respectively introduced the operation situation of their respective industries in 2023, as well as the demand and application of stainless steel.
Su Changyong, Deputy Secretary General of China Iron and Steel Industry Association and Party Secretary and President of Metallurgical Industry Press, stated in his speech that there is still room for growth in stainless steel consumption. He believes that the current high export volume of stainless steel can still be maintained for a period of time. At the same time, he proposed that the high-quality development of the stainless steel industry should pay attention to issues such as overcapacity, raw material supply, stainless steel innovation, and changing the image of stainless steel.

Xiangshui Defeng Metal Materials Co., Ltd. has successfully applied for a patent titled "A slitting longitudinal cutting mechanism for hot-rolled stainless steel coils"
On January 23, 2024, Xiangshui Defeng Metal Materials Co., Ltd. successfully applied for a patent titled "A slitting longitudinal cutting mechanism for hot-rolled stainless steel coils", with application publication number CN117428498A and application date of November 10, 2023.
The invention relates to the field of plate cutting technology, in particular providing a slitting longitudinal cutting mechanism for hot-rolled stainless steel coil plates, including a workbench, a cutting blade, a discharge plate set below the discharge side of the workbench, the discharge plate gradually tilts downwards towards the left-hand side of the workbench, and a vertical support frame is fixed on the top surface of the discharge plate, with a receiving mechanism installed at the top of the support frame, The discharge end of the workbench is equipped with a discharge plate located below the receiving mechanism, which utilizes the self weight generated by the steel plate falling on the receiving plate to deflect the inner end of the receiving plate downwards, thereby polishing the burrs on the two shear ends of the steel plate. When the steel plate cuts and discharges, it can self check whether there are burrs on its two shear ends, and achieve the goal of synchronous discharge and burr cleaning. When burrs appear on the steel plate, there is no need to stop the machine to inspect the cutting blade, and mass production will not affect normal production.

Baowu Teye Aviation Research Technology Co., Ltd. has successfully applied for a patent titled "Preparation method of martensitic sulfur-containing free cutting stainless steel for aviation"
On January 23, 2024, Baowu Teye Aviation Research Technology Co., Ltd. successfully applied for a patent titled "Preparation method of martensitic sulfur-containing free cutting stainless steel for aviation", with application publication number CN117431454A and application date of October 26, 2023.
The invention discloses a preparation method for aviation grade martensitic sulfur-containing free cutting stainless steel, which includes adding industrial pure iron, nickel plate, low-carbon chromium iron, and the steel grade return material to an electric furnace for melting, adjusting the steel composition to control the composition, according to weight percentage: C: 0.22~0.25%, Si: 0.10~0.25%, Mn: 1.10~1.20%, P: 0.10~0.13%, Cr: 12.50~13.50%, Ni: 1.65~1.90%; Insert sulfur powder sealed with a thin tube into the steel liquid, stir evenly, then add BaAlSi alloy for final deoxidation, and then pour it out of the furnace into an electric slag billet; Perform electroslag remelting on the electroslag billet, using an electroslag remelting slag system that includes 30-40 wt% CaF2 powder, 25-35 wt% Al2O3 powder, 20-30 wt% SiO2 powder, 3-7 wt% MgO powder, and 3-7 wt% metallic manganese particles; After the electroslag remelting of the ingot, it is sent to the forging hot working furnace for heating, and then forged. After forging, it is sent to the annealing furnace for annealing heat treatment to obtain martensitic sulfur-containing free cutting stainless steel for aviation. This preparation method can effectively control the content of sulfur and manganese elements, and improve the comprehensive yield of Y25Cr13Ni2.
