Why will the analysis of the causes of oxidation of Thread Insert

Thread Insert is short for acid-proofThread Insert, resistant to weak corrosive medium such as air, steam, water, or with a Thread Insert grade is called Thread Insert;And resistance to chemical corrosion medium (acid, alkali, salt and other chemical etching) corrosion of steel called acid-resistant steel.Due to the differences in chemical composition and make them both the corrosion resistance of different, ordinary stainless steel is generally not resistant to chemical corrosion medium, and acid is commonly have Thread Insert.


Stainless steel often according to the state of organization can be divided into: martensite steel, ferritic steel, austenitic steel, austenitic (two-phase) - ferrite stainless steel and precipitation hardening stainless steel, etc.In addition, according to ingredients can be divided into: chromium stainless steel, chromium nickel Thread Insert and chromium manganese nitrogen Thread Insert, etc.Fasteners use Thread Insert as the material, it can be said that no matter in the manufacture, use or processing of each link have very big advantage, so although fasteners with Thread Insert as the material itself cost higher, cycle life is relatively short, but in the fastener solution but still belongs to a kind of more savings.
Fasteners, if use Thread Insert as the main material is also to know about the problem of magnetic Thread Insert itself.Stainless steel is generally considered not magnetic, but actually austenite system column material after a certain processing technology, is likely a certain magnetic, but if regard magnetic is judging the quality of stainless steel fasteners, standard is not accurate.
Fasteners, when selected, Thread Insert material have magnetic doesn't mean the quality of high and low, some chromium manganese Thread Insert is not actually a magnetic Thread Insert.In Thread Insert fasteners, stainless steel and chromium manganese can't replace the use of 300 series Thread Insert, especially in high corrosive medium business environment.
