202 stainless steel is one type of the 200 series stainless steel. Its national standard model is 1Cr18Mn8Ni5N. 202 stainless steel is widely used in architectural decoration, municipal engineering, highway guardrails, hotel facilities, shopping malls, glass handrails, public facilities and other places.

Does 202 stainless steel have magnetism?
Stainless Steel 202 Sheet usually has a weak magnetic property.
SS202 material selection suggestions?
In scenarios where strict magnetic-free conditions are required, such as for electronic equipment shielding covers, it is recommended to use 304 austenitic stainless steel. For ordinary decorations or structural components, 202 stainless steel can be chosen, as it offers more cost advantages.
Conversion relationship between thickness and weight for SS202?
0.5mm thin sheet: 0.5 × 7.93 ≈ 3.97 kg/m²
3mm medium-thick plate: 3 × 7.93 = 23.79 kg/m²
6mm thick plate: 6 × 7.93 = 47.58 kg/m
The “waterproofing secret” of 202 stainless steel?
This SS 202 Sheets contains 17% chromium, 4% nickel, and a small amount of manganese. Its surface naturally forms a protective layer of chromium oxide. It can prevent water molecules from penetrating, so it can handle daily rainfalls and humid environments without any problem.
SS 202 Sheet Load-bearing capacity?
The load-bearing capacity of Stainless Steel Grade 202 (UNS S20200) mainly depends on two factors: thickness and processing technology.
For instance, a 2mm thick 202 stainless steel plate can support approximately 1.5 tons of weight per square meter (equivalent to a small car pressing on it).

AISI 202 (S20200) Stainless Steel is an economical type of stainless steel with a high manganese content. It forms an oxide chromium protective film by adding chromium elements to prevent rusting.
Three scenarios prone to rusting.
Practical suggestions for extending the service life
• Regularly wipe the surface
• Avoid using in combination with carbon steel
• Store in a dry and ventilated environment
• Deal with rust spots promptly if found
