Stainless steel mesh punching processing of stainless steel material can use magnet for inspection

Some customers to identify the stainless steel mesh stamping products, is to use magnets! Not absorption is good, it is stainless steel, absorb is poor, is' stainless iron! The current practice of this statement, seem to be very popular, even with science and technology periodicals, TV shows are pushing through this method. Stainless steel in the market roughly divided into two kinds: one kind is austenite size ( Mostly in the 300 series, 200 series) Often nonmagnetic, but after processing may exist weak magnetism, the other is a martensite ( Iron grain size) The ferritic stainless steel ( Mostly in the 400 series brand) , duplex stainless steel, martensite stainless steel, precipitation hardening stainless steel with magnetic. Two kinds of stainless steel is magnetic, so use magnets to verify the advantages and disadvantages of stainless steel mesh material is not correct, industry experts also pointed out that the practice is not scientific. Stainless steel tiny tiny mesh can be used in the structure of the ceiling, wall panel sound-absorbing materials; Can be used for building staircases, balcony, environmental protection furniture elegant decorative orifice plate; Can be used to shield of mechanical equipment, speaker net, food, feed, mines with grinding ore sieve, sieve, sieve, h kitchen equipment with stainless steel fruit blue cover, food, fruit tray, such as kitchen utensils and appliances, and shopping malls shelf, decoration exhibition platform, grain ventilation breathable mesh, football field lawn ooze water filter water filter.
