优质不锈钢紧固件是高附加值产品,欧美市场售价高达每吨一万美元,国内外都有广阔市场.开发不锈钢紧固件,不仅能产生巨大的经济效益,还可以将紧固件生产的工艺技术提高到一个新的水平,这对改变国内紧固件行业的面貌,提高中国紧固件行业在国际同行业中的声誉和地位都有重大作用.开发不锈钢紧固件难度较大.与普通碳钢相比,不锈钢冷加工硬化明显、导热性差(导热系数约为碳钢1/4)、线膨胀系数大,导致冷镦变形抗力大、发热量高、散热差,并带来一系列同题.总之,若要开发不锈钢紧固件成功,必须抓住材料、软化处理、润滑、工模具、产品光亮热处理和表面抛光等关键,缺一不可.
High-quality stainless steel fasteners are high value-added products, the European and American markets price as high as 10,000 US dollars per ton, both at home and abroad have a vast market.Development of stainless steel fasteners, not only can produce huge economic benefits, but also the fastener production Of the technology to a new level, which changes the face of the domestic fastener industry, China’s fastener industry to improve the reputation and status in the international industry have a significant role in the development of stainless steel fasteners more difficult. Compared with ordinary carbon steel, stainless steel hardened significantly cold, poor thermal conductivity (thermal conductivity of about 1/4 of carbon steel), linear expansion coefficient, resulting in cold heading deformation resistance, high heat, heat dissipation and bring a series In short, to develop the success of stainless steel fasteners, we must seize the material, softening treatment, lubrication, tooling, bright heat treatment and surface polishing and other key, are indispensable.
