Stainless Steel Plates for Metal Products, Machinery and Equipment Repair Industry: 316L/2205 Selection and 3 Item Lists
For the Metal Products, Machinery and Equipment Repair Industry, we have organized three stainless steel parts: commonly used 316L / 2205 / 304, with thickness ranging from 0.8–10 mm.
Three Parts and Material Lists
| Part / Component | Recommended Grade | Specifications / Thickness | Surface | Main Failure Modes | Reference Standards |
|---|---|---|---|---|---|

Consider usage conditions rather than specifying grades
- Most common grades in this industry are 316L (3), 2205 (2), and 304 (1) — parentheses indicate the number of parts involved, useful for quoting and material ordering.
- Thickness range: 0.8–10 mm. Thin plates are often formed pieces (considering bend back and deep drawing cracking), thick plates are typically welded structures (considering heat input and sensitization).
Frequently Asked Questions
What stainless steel is used most in metalworking, machinery, and equipment repair?
By total pages, the top three are 316L (3), 2205 (2), and 304 (1). For specific parts, look at the medium and temperature, for example, stainless steel countertops require 316L when exposed to saltwater.
Which part is the easiest to have problems with?
What type of corrosion? Typical example: Acid pickling and passivation service contacts; Corrosion by HNO₃/HF+Cl⁻. Recommended grade 316L/acid-resistant plastic liner, size 2–10mm. For this condition, specify medium concentration, temperature, and cleaning method in the design phase.
How thick should it be?
Thickness range in the list is 0.8–10 mm. Thin plates consider forming and surface quality, thick plates consider weld strength and structural integrity; different manufacturers may have varying values for the same location, review your drawings or conditions to confirm.
