What is 202 grade stainless steel?
Grade 202 is chromium-manganese-nickel stainless steel with high toughness at low temperature. In comparison, grade 202 has less nickel content unlike 304. Hence it offers low corrosion resistance and lower toughness. But it is a less expensive substitution for grade 304 in many applications.

Grade 202 stainless steel is a type of Cr-Ni-Mn stainless with similar properties to A240/SUS 302 stainless steel. The toughness of grade 202 at low temperatures is excellent.

It is one of the most widely used precipitation hardening grades, and possesses good corrosion resistance, toughness, high harness, and strength.

The following datasheet provides an overview of grade 202 B stainless steel.

Difference between grade 304 and grade 202 stainless steel

Grade 304 and 202 are austenitic non-magnetic stainless steel. Both are containing nickel, but the concentration of nickel is not the same. Grade 304 contains 8% nickel, whereas 202 SS has around 4-6% nickel. This makes a huge differentiating parameter between the two.

Grade 304 is vastly used commercial stainless steel. It is also known as 18/8 stainless steel. Grade 304 offers excellent streamline characteristics of corrosion resistance with excellent forming and welding characteristics.

Grade 202 is chromium-manganese-nickel stainless steel with high toughness at low temperature.

In comparison, grade 202 has less nickel content unlike 304. Hence it offers low corrosion resistance and lower toughness. But it is a less expensive substitution for grade 304 in many applications.

Chemical Composition

Grade	Carbon	Mn	Si	P	S	Cr	Ni	N
304	0.08	2.0	0.75	0.045	0.030	18-20	8-10.5	0.10
202	0.15(max)	7.50-10	1.0	0.060	0.030	17-19	4-6	0.25

 

The more content of nickel in 304 attributed towards its cost. Grade 304 is more expensive than grade 202.

Applications

The grade 202 steel can be made into plates, sheets, and coils to be used in the following:

• Restaurant equipment
• Cooking utensils
• Sinks
• Automotive trim
• Architectural applications such as windows and doors
• Railway cars
• Trailers
• Hose clamps.

     4. Packaging 

    In the steel export activities, we also need to pack the steel to prevent the steel from being scattered in the transportation process. In the hoisting process, it is necessary to lift the steel. So steel is very necessary in the export process. Below is the picture of packaging：

According to the requirements of the state of steel materials, the use of binding, bare, frame, pallet.

Packing standard: according to the following national standard requirements (the parts beyond the requirements will be specified separately)

GB／T191 packaging-pictorial marking for handling of goods

GB／T4857 (all parts) basic test for transport packages

GB／T4879 rustproof packaging
