上海钢铁研究所为核工业部二院研制的Gr20Mn10Ni4Si13N抗咬死耐酸不锈钢新钢种,经过几年的努力,终于在七月份通过技术鉴定。该钢种先后提供14吨料给多家用户使用,满足了用户对数量的要求,并由原来的150公斤真空感应炉冶炼的生产方式,改为电弧炉冶炼方式。该钢种解决了1Cr18Ni9Ti在无油润滑条件下的咬死问题,是目前国内最好的抗咬死耐酸不锈钢种,并且焊接及机械加工性能良好。新钢种延长了设备的使用
Shanghai Institute of Iron and Steel Co., Ltd. Gr20Mn10Ni4Si13N anti-seizure acid-resistant stainless steel new steel grades developed for the second hospital of the Ministry of Nuclear Industry, after several years of hard work, finally passed the technical appraisal in July. The steel has to provide 14 tons of material to a number of users to use to meet the user requirements on the number of the original 150 kg vacuum induction furnace smelting production methods to electric arc furnace smelting. The steel to solve the 1Cr18Ni9Ti biting in the oil-free conditions, is the best anti-seizure acid-resistant stainless steel species, and welding and machining performance is good. The new type of steel extends the use of equipment
