In the process of using fasteners, many people think that a small fastener replacement will not make a big difference. As everyone knows, this idea is not correct. Fasteners, as important parts of machinery, must be installed strictly in accordance with the requirements of different types in the pro

As for fastener products, the following standard conditions must be met during production to ensure the customer's utilization of fastener product quality. What are the standard conditions for fastener products? There are five main types.1, fastener product size standards: specify the basic size of

Without surface treatment: At present, among stainless steel fasteners, according to our experience, taking 304 products as an example, without any surface treatment, the general salt spray test time for stainless steel screws is 48 hours, and the nut is 96 hours. However, affected by the rough surf

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

As we all know, the strength of austenitic stainless steel 304 and 316 fasteners is divided into 70 or 80 grades (such as A2-70, A4-70 or A2-80, A4-80), many people will ask the equivalent of carbon steel tightness What is the firmware level?According to the requirements of the Circumvention 098.1-2

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
