Q: What kind of stainless steel banding for watch?
A: Swiss watch is generally used with steel 316L, except Rolex(904L)
316L is 300 series from U.S. and Japan, which is a common austenitic stainless steel.
By GB, should be 00Cr17Ni14Mo2.
Chemical composition: content (%)
Carbon (C) <= 0.03
Manganese (Mn) <= 2.0
Silicon (Si) <= 1.0
Nickel (Ni) 12 - 16
Chromium (Cr) 16 - 18
Molybdenum (Mo) 1.8-2.5
Sulfur (S) <= 0.030
Phosphorus (P) <= 0.035
904L is a high chromium, nickel, molybdenum content, low carbon austenitic stainless steel, which has a very good corrosion resistance.
Correspondence should be 00Cr20Ni25Mo4.5Cu GB
904L components:
C ≤ 0.02, Fe42.0-53.0, Cr19.0-21.0, Ni24.0-26.0, Cu1.0-2.0
S ≤ 0.035, Mo4.0-5.0, Mg ≤ 0.01, P ≤ 0.045, Si ≤ 1.0 |
