High temperature resistant ASTM A325 high-strength bolts

Advanced bolts are the foundation of high-end mechanical manufacturing, and their function can be referred to as "pulling a thousand pounds in four or two directions". On the surface, the output value of bolts only accounts for a few percent of the mechanical industry. In essence, it brings much higher added value to key components and equipment. For many years, after continuous double-digit growth, the Bolt industry in China experienced negative growth in 2012, with a year-on-year decrease of about 1.5%. The main reason was insufficient market demand, especially the decline in export sales of bolts after being subjected to international anti-dumping measures.
