The chemical composition is the biggest difference between these two stainless steel grades. Grade 201 is composed of 16-18% chromium, 3-5% nickel and up to 0.15% carbon. Grade 202 has 17-19% chromium, 4-6% nickel and 0.15-0.25% carbon. The presence of both chromium and nickel in grade 202 helps it form a protective layer on its surface which prevents oxidation from occurring; this allows grade 202 to remain more durable over time than grade 201, which tends to be more susceptible to rusting due to its lower levels of chromium content. The main difference between 201 and 202 stainless steel is the composition. 201 stainless steel contains a lower percentage of manganese and chromium, while 202 stainless steel contains higher levels of manganese and chromium.
