Heavy-gauge material for demanding equipment. Metalex can discuss grade, form, finish, dimensional tolerances, documentation and packing with your procurement team. Confirm stock and delivery against your purchase specification.
304/304L · 316/316L · 310S · 321 · 409 · 410 · Duplex 2205. Other grades: specifications on request.
Combined sheet/plate/coil catalogue range: width 1,250–2,500 mm, length up to 6,000 mm and thickness 0.1–50 mm. Plate-specific feasible thickness and cut sizes depend on grade and mill supply. Chequered plates, cut blanks and flange rings are among its forms.
Listed stainless flat grades include 304/304L, 316/316L, 904L, 310/310S, 321, 409, 410, 202 and 17-4 PH; duplex S31803/S32205 and super duplex S32750/S32760. 430 is not in this catalogue; ask if needed rather than treating it as a listed grade.
Metalex catalogue (2022) describes a product range, not real-time stock or a test certificate. Confirm grade, dimensions and documentation for your enquiry.
| Detail | Options to specify |
|---|---|
| Heavy flat plate | Flat-rolled stainless plate under a chosen standard such as ASTM A240/ASME SA240. Confirm grade, thickness and test requirements. |
| Grade range | 304/304L · 316/316L · 310S · 321 · 409 · 410 · Duplex 2205 |
| Plate dimensions | State thickness × width × length, flatness, cut method and edge condition. |
| Plate finish | Mill or processed finish as specified; polished finishes depend on grade and thickness. |
| Documentation | Ask which certificate and heat or batch traceability documents are available for the specific material offered. |
For plates, give the grade/UNS, material standard, thickness, width, length, flatness, quantity and destination. Ask for lot-specific certification and any required inspection.
Heavy plate differs from thin sheet and coiled strip. Confirm cut size and tolerances before ordering.
| Grade | Typical selection reason | Check before ordering |
|---|---|---|
| 304 / 304L | General fabrication and mild process environments | Welded assemblies: verify L-grade certification |
| 316 / 316L | Added molybdenum for improved pitting resistance in many chloride environments | Assess chloride concentration, temperature and crevices |
| Duplex 2205 | Higher yield strength and better chloride SCC resistance than common austenitic grades | Confirm UNS S32205 or S31803 and welding procedure |
