There are many types of stainless steel. Bebon International these stainless cash resources. 201 stainless steel and 304 stainless steel except that the chemical elements nickel content is low .200 series stainless, rust, then the time of purchase stainless how to identify it? Bebon International steel exporter for you to answer.
Color difference:
After pickling of stainless steel, surface color silver Bai Guangjie: chrome-nickel stainless steel color silver Bai Chengyu color; chrome stainless steel color white slightly gray sheen weak; CrMnN color and chrome-nickel stainless steel similar paler. Without the pickling of stainless steel surface color: chrome-nickel steel brownish white; chrome steel brownish-black; CrMnN was black, (three color refers to the color of oxidized heavier). Cold-rolled annealed without chrome-nickel stainless steel, silver reflective surface. In addition to stainless steel element, in general, are pickled white.
With copper sulphate identification:
Method is to remove the oxide layer on steel, put a drop of water, wipe with copper sulfate, if not change color after wiping, generally of stainless steel as to purple: a non-magnetic high manganese steel, the magnetic steel is generally normal or low alloy steel.
With magnet identification:
Magnet can basically distinguish two types of stainless steel. Because chromium stainless steel in any state can be a magnet to attract; chrome-nickel stainless steel in the annealed condition is generally nonmagnetic, after cold working, and some will be magnetic. However, high manganese high manganese steel is non-magnetic; chrome-nickel stainless steel magnetic nitrogen situation is more complicated: Some non-magnetic, some are magnetic, and some non-magnetic and transverse vertical plane surface is magnetic. So, to say, although the magnet can basically distinguish chromium stainless steel and chrome-nickel stainless steel, but can not correctly distinguish some special properties of steel, but can not distinguish between specific steel.
Bebon International provided method of identifying, by the above method we can identify the type of steel can not identify a specific Arranging.More information about stainless steel,please contact us, you can also send your detailed requirements to our email, we will reply within the shortest possible time.
