It is understood that China's domestic and foreign about 40,000 varieties , specifications of millions of fasteners in various forms , and their use of occasions and the environment is ever-changing . Such as: industrial profile parts as the host , a connector member , together with the host body bears the basic performance of the basic functional components of the requirements that must adapt to high temperatures . Hypertension. Hypothermia . Vibration. Corrosion, overloading, alternating stress , torsional shear and other occasions . However , the probability of accidents caused by failure of the fastener is very high, and therefore the material for manufacturing the fastener must first have strict selection .
Many domestic enterprises due to product quality issues fasteners after another encounter customers high claims . Indeed , many of the quality problems are caused due to material failure . How to choose the right material for fasteners fastener enterprises become increasingly concerned about one of the topics .
Steel fasteners for our current situation and existing problems , China General Machine Components Industry Association Professional Association of Fastener Materials Engineering Consultant Shen said: Although it is a fastener China is currently the largest producer , is also the world's first steel-producing countries , but the development and production of steel fasteners development started late . Cold heading steel of different specifications than less , can not meet the current domestic demand and exports fasteners production needs . Cold heading steel production and market liquidity also borrowed heavily from the JIS Standard G3506, G3507, G4105 , and many of the American ASTM steel grades.
