Why would Thread Insert oxidation of root cause analysis

Fasteners, if use stainless steel as the main material is also to know about the problem of magnetic stainless steel 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.
have spentFasteners, when selected, stainless steel material have magnetic doesn't mean the quality of high and low, some chromium manganese stainless steel is not actually a magnetic stainless steel.In stainless steel fasteners, stainless steel and chromium manganese can't replace the use of 300 series stainless steel, especially in high corrosive medium business environmenthave spentFasteners of nickel element USES have spentFasteners in the process of using stainless steel as material, ever more dependent on the use of nickel element, but in the case of nickel element global prices, price of fasteners is affected by the larger.Fasteners production enterprises in order to ease the cost pressure, improve the competition ability of fasteners, especially looking for alternative materials, production of low nickel stainless steel fasteners.
