304 Stainless Steel Test

1. TOOLS

1.1 Carbon Sulphur Tester

1.2 ICP

2. STANDARD

GB/T 223 

3. TESTING PROCEDURE

3.1 Grind sample into powder

3.2 Melt powder with acid

3.3 Place the melted powder into the Carbon Sulphur Tester (for C and S) and into the ICP

(for P, Mn, Si, Cr and Ni)

4. ASSESSING TEST RESULTS

Test Items

304 SS Standard (%)

Chemical
Element

C

≤ 0.080

S

≤ 0.030

P

≤ 0.045

Mn

≤ 2.000

Si

≤ 0.750

Cr

18.00 - 20.00

Ni

8.00 - 10.50

If the percentual values of all elements meet the standard, the stainless steel material is deemed compliant with GB/T 223 and thus qualifies as 304 stainless steel.
