In the process of production of stainless steel round bar, stainless steel flat steel can appear some leftover material, these leftover material have also been many enterprises make full use of rise, but everyone will wonder the leftover material is the same with ordinary steel scrap stainless steel scrap, if not the same as what is the difference between them?
1, from the toughness and hardness difference: ordinary scrap steel soft and resilient, easy bending is not easy to break; Hard chromium stainless steel scrap sex, ZaJi bend cannot be broken; Nickel chromium stainless steel scrap tenacity, ZaJi can bend can't break.
2, from the oxidation resistance difference: ordinary scrap steel is easy to oxidize, yellow; Chromium stainless steel scrap is not easy to rust; Nickel chromium stainless steel scrap is not easy to rust.
3, from the color difference: ordinary scrap dark brown; Acid treatment of chromium stainless steel scrap is white; Not pickling brown and black; Acid treatment of nickel and chromium stainless steel scrap is silvery white; Ammonia manganese steel pickling brown and white (road in black, hard); Cold rolling without annealing is silvery white, reflective, hard.
4, from the magnetic difference: huaxiang think ordinary steel scrap in any case can be attracted by a magnet; Chromium stainless steel scrap of magnetic, can be a magnet to attract; Nickel chromium stainless steel scrap in annealing state, non-magnetic. After cold working, and there will be a little magnetic, but high manganese content in manganese steel and high manganese steel road no magnetism.
5, from the luster difference: ordinary scrap without oxidation luster; Chromium stainless steel scrap without luster; Nickel chromium stainless steel scrap.
6, wipe with copper sulfate difference: ordinary scrap is purple; Chromium stainless steel scrap does not change color; Nickel chromium stainless steel scrap scrape the oxide layer, drop a little water, copper sulfate, wipe the discoloration.
