Product Description

201 stainless steel material has certain acid and alkali resistance, high density, no bubbles or pinholes during polishing, and other characteristics.

201 stainless steel is not a food grade material, as it has a high manganese content and poor corrosion resistance. If stored as a liquid in a thermos cup for a long time, it may lead to the precipitation of manganese elements. The current steel grades include J1, J3, 201, 202, etc., which have lower chromium content than 304 stainless steel and faster corrosion rate in acidic environments.

Chemical composition

(C) Carbon: ≤ 0.15

(Si) Silicon: ≤ 0.75

(Mn) Manganese: 5.5-7.50

(Cr) Chromium: 16.0-18.0

(N) Nitrogen: ≤ 0.25

(P) Phosphorus: ≤ 0.060

(S) Sulfur: ≤ 0.030

(Ni) Nickel: 3.5-5.5

China mainly has the following 200 series steel grades: J1, J2, J3, J4201202. Later on, steel grades such as 200 with lower nickel content control emerged. As for 201C, it is an extended steel grade developed by some Chinese steel mills in the later stage. The national standard grade of 201 is the old grade 1Cr17Mn6Ni5N and the new grade 12Cr17Mn6Ni5N. 201C continues to reduce the nickel content and increase the manganese content on the basis of 201.
