How to detect if it is really stainless steel?

As a company that has been in business for more than 30 years, we know what our customers need and what they care about.

After more than 30 years of development, we continue to learn, innovate, and meet customers with a better look. Every cargo and service we provide is strictly in accordance with company regulations.

We always believe that the business philosophy of no fraud is the principle of doing things that we have been pursuing and the reason why customers believe us.

Today I am here to tell you how to identify whether it is real stainless steel wire mesh.

Identification of color: After pickling stainless steel, the surface color is silvery and white: chrome-nickel stainless steel is silvery white; chrome stainless steel is slightly grayish and gray; chrome-manganese-nitrogen stainless steel is similar in color to chrome-nickel stainless steel. The surface color of stainless steel without pickling: chrome-nickel steel is brownish white, chrome steel is brownish black, and chrome-manganese nitrogen is black (the three colors refer to the heavier oxidation color). Cold-rolled, unannealed chrome-nickel stainless steel with reflective white surface.

Identification with magnets: Magnets can basically distinguish between two types of stainless steel. Because chrome stainless steel can be attracted by magnets under any condition; chrome-nickel stainless steel is generally non-magnetic in the annealed state, and some may be magnetic after cold working. However, high-manganese steel with higher manganese content is non-magnetic; the magnetic condition of chrome-nickel-nitrogen stainless steel is more complicated: some are non-magnetic, some are magnetic, some are non-magnetic in the longitudinal plane and magnetic in the transverse plane. Therefore, although the magnet can basically distinguish between chromium stainless steel and chrome-nickel stainless steel, it cannot correctly distinguish some special-purpose steel grades, and it is impossible to distinguish the specific steel grades.

Identification with copper sulfate: remove the oxide layer on the steel, put a drop of water, rub it with copper sulfate, if it does not change color after rubbing, it is generally stainless steel; if it turns purple, non-magnetic is high manganese steel, it is magnetic It is ordinary steel or low alloy steel.

These are just basic identification methods. If you want to carry out the identification in depth, please look for a special testing agency for testing.
