01 Advantages of cold headingHigh utilization rate of steel: cold heading (extrusion) is a kind of less, no cutting processing method, such as processing rods hex head bolts, cylindrical head hex screws, using the cutting method, steel utilization rate is only 25% ~ 35%, and with cold heading (extru

Now the use of stainless steel for manufacturing fasteners has been very popular, but for stainless steel fasteners, there are four major performance points, which are described as follows:1. High temperature resistance of stainless steel fasteners. Because of the hardness of stainless steel itself

Adaptability in high temperature environment: According to the GB/T3098.6-2014 standard, stainless steel 304 and 316 products do not affect the tensile strength within 100 °C, but after the temperature exceeds 100 °C, the tensile strength decreases by 5% for every 100 °C increase in temperature. Not

At present, there are some methods to quickly detect the authenticity of stainless steel fasteners on the market, such as the use of stainless steel potions and magnets, but after years of verification, these two methods are not scientific. Relevant qualitative standards, different experimental meth
