Products Specification

202 Stainless Steel

Type 202 is an Austenitic Standard grade stainless steel and considered a chromium-manganese-nickel stainless steel. Type 202 is similar in properties and quality as it possesses good corrosion resistance, toughness, high harness, and strength and is extremely tough at low temperatures.

What is the difference between ss 304 and ss 202?

Both grades 304, as well as grade 202 stainless steel, belong to the austenitic class. This means that the microstructure of both stainless steel alloys is face-centered cubic. Since grade 304 is an alloy that falls under the 300 series stainless steel, this alloy inherits its austenitic structure primarily the inclusion of a higher content of nickel added to its alloy. On the other hand, grade 202 falls under the 200 series stainless steel. Grades that belong to the 200 series stainless steel, tend to substitute elements such as manganese and nitrogen in their chemistry, as an effective alternative for the element nickel. This being said, it is interesting to note that there still is a small inclusion of nickel content in their alloys.

How to Identify ss 304 and ss 202?

The most efficient way of identifying two different steel grades is by requesting the manufacturer for an MTR or what is referred to as a certified Material test report. So in addition to obtaining a more straightforward interpretation of the chemical makeup of each stainless steel alloy, it is also possible to procure a detailed report on both their mechanical properties, as well as their physical properties. However, in the market, it is possible to do a small test to gauge the difference. A spark test although inconclusive could separate the two grades. On running a grinder over the alloy, sparks for grade 304 do not fly, they have a reddish-orange tinge appearance and are thin. The grinder test for grade 202 yields thicker, yellow sparks that fly a lot.

SS 304 and ss 202 uses and application

Applications for grade 304 stainless steel include Kitchen benches, sinks, troughs, equipment, and appliances in addition to Food processing equipment, particularly in beer brewing, milk processing & winemaking. Furthermore, because this alloy grade is stronger, and is very ductile, its use also includes Woven or welded screens for springs, mining, Heat Exchangers, quarrying & water filtration, Architectural paneling, railings & trim, Chemical containers, including for transport along with its use as Threaded fasteners. On the other hand, grade 202 proves useful as various Kitchen Sinks, Cookery appliances, Hose clamps, Restaurant Equipment, Automobile trim, Railway bogeys, Trailers, as well as architectural treatments, for instance - windows or doors.

SS 304 and ss 202 Weldability

As with several austenitic alloys, it is possible to weld grade 202 by use of conventional fusion techniques. The alloy also permits the use of resistance methods for welding. However, this particular grade is not suited to be joined by the use of the oxyacetylene welding method. Yet, the higher content of carbon makes it prone to intergranular corrosion. Grade 304, which has a higher content of carbon faces a similar issue. But this is easily changed by altering the content of carbon in grade 304 to make it lower. Although the grade would become grade 304L, it is possible to get a dual certification. Hence, the revised grade becomes 304/304L, which could be welded using any traditional welding process.
