202 Stainless Steel Sheet

202 stainless steel sheet belongs to the low nickel high manganese steel.The nickel content is generally below 4%, manganese content is about 8%, it is  nickel-saving stainless steel.202 stainless steel is superior than 201 stainless steel in performance. In chemical composition, we can see that the 200 series stainless steel is added nitrogen. Nitrogen can improve the strength of steel, low temperature toughness and weldability, increasing sensitivity, so the strength of 200 series is tough and the welding performance is relatively good.

We are engaged in offering an extensive range of Stainless Steel . Fabricated using quality assured raw material, which are procured from well-known vendors, our range is highly durable and rugged in construction. Delivered after a stringent quality check, our range meets all the specific requirements of clients and set industry standards.


Application 

202 stainless steel sheet is widely used in building decoration, hotel facilities, shopping malls, glass handrails, public facilities and other places. By the High-precision automatic pipe-making equipment, through its own etching welding, roll forming, in the absence of any metal filler, filled with gas protection (inside and outside the pipe) welding, welding mode for TIG process, and on-line solid-Solution eddy current testing.

202 stainless steel plate belongs to metastable austenitic stainless steel, its GB grade is 1Cr18Mn8Ni5N, has high strength, toughness, high abrasion resistance and has a larger processing hardening.


What's the difference of 304 Stainless steel sheet and 202 stainless steel sheet  

304 stainless steel sheet is a common kind of stainless steel material, the density is 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature 800 degrees, with good processing performance, high toughness characteristics, widely used in industrial and furniture decoration industry and food medical industry. The common methods of marking on the field include 0cr18ni9 and SUS304.

202 stainless steel is one of 200 series stainless steel, the GB model is 1cr18mn8ni5n. 200 Series stainless steel belongs to low NI high manganese stainless steel, nickel content, manganese content is about 8%, is the nickel-type stainless steel.


Differentiating Methods

1. Color difference

After pickling of stainless steel, the surface color white and smooth: chrome-nickel stainless steel color silver jade, chrome stainless steel slightly gray luster weak; chromium-manganese-nitrogen stainless steel is similar in color to chrome-nickel stainless steel slightly. The surface color of stainless steel without pickling: nickel is brownish-white, chrome is brownish-black, and chromium-manganese nitrogen is black, which is the color of the three colors. Cold-rolled annealed chrome-nickel stainless steel with a shiny silver surface. Stainless steel In addition to the yuan steel, generally by pickling white.

2. Copper Sulfate

The method is to remove the oxide layer on the steel, put on a drop of water, rub with copper sulfate, after wiping if not discoloration, generally stainless steel; such as purple red: non-magnetic for high manganese steel, magnetic generally ordinary or low alloy steels.

3. Magnet 

A magnet can basically distinguish between two types of stainless steel. Because chromium stainless steel in any state can be magnet attraction; chromium-nickel stainless steel in the annealing state is generally non-magnetic, after cold processing, some will have magnetic. However, high manganese steel with higher MN content is non-magnetic, and the magnetic condition of chromium-nickel-nitrogen stainless steels is more complex: some non-magnetic, some magnetic, some longitudinal surface non-magnetic and the transverse surface has magnetism. Therefore, although the magnet can basically distinguish between chrome stainless steel and chromium-nickel stainless steel, but can not correctly distinguish some of the special properties of steel, but also can not distinguish the concrete number.


Corrosion Resistance

Stainless steel will rust under certain conditions. Stainless steel has the ability to resist atmospheric oxidation--that is, it is not rust, but also has the acid, alkali, salt in the medium is corrosion of the ability--that is, corrosion resistance.

However, the corrosion resistance is changed with the chemical composition of the steel itself, the mutual state, the use condition and the environmental medium type. such as 304 steel pipe, in the dry and clean atmosphere, there is an absolute excellent corrosion resistance, but move it to the seaside area, in a large amount of salt in the sea fog, will soon rust, and 316 steel pipe performance is good.

So, not any kind of stainless steel, in any environment will be capable of corrosion, not rust.

 

Therefore, if you want to buy 202 stainless steel, please first understand your specific use and use of the environment, so as not to give you an unnecessary trouble. If you need specific price, please contact us in time
