High strength bolt quality matters needing attention

Hardware fasteners have always been dominated by steel materials. Due to fierce market competition, quality and cost have become the main means of competition for fastener companies. Luo Baihui believes that there are two main ways to reduce costs: 1. Reduce the content of alloy elements or use other low-cost alloy elements as strengthening materials; 2. Reduce the manufacturing cost of fasteners, such as non-modulating steel used to reduce the heat treatment process in the production process of bolts, and free-cutting steel used to improve the machining capacity of nuts. The introduction of technology in China's automobile industry has played a role in promoting the application of new materials for cold heading steel. Some major high-strength fasteners have adopted corresponding foreign material standards. Luo Baihui believes that in order to achieve the goal of saving resources, the research and development of special steel for special bolts will be paid attention to in the next 3-5 years. This is also the trend of tight enterprises in the situation of soaring raw material prices.

Always pay attention to, grasp the procurement opportunity

For fastener manufacturers, all finished products are inseparable from the large-scale purchase of raw materials such as iron ore and wire rod. The price of raw materials is too fast and too fierce, which has made it difficult to follow up downstream demand. It may be difficult to avoid a sharp correction in the later period. The price fluctuation of raw materials plays a decisive role in the procurement cost of fastening enterprises in China. Actively purchase raw materials at relatively low prices to prepare for future mass production to reduce costs. Therefore, being able to pay attention to raw material price fluctuations and buy at low cost is also one of the conditions for the success of a business decision maker.
