Stainless Steel Sheet
Stainless steel plate is an alloy steel with smooth surface, high weldability, corrosion resistance, polishability, heat resistance, corrosion resistance and other characteristics. It is widely used in various industries and is an important material in modern industry. Stainless steel is divided into austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, and duplex stainless steel according to the structure state.

Classification of Stainless Steel
| iron + carbon = steel |
| + chromium = stainless steel （at least 10.5% chromium） |
| | martensitic alloys | austenitic alloys | duplex alloys | precipitation hardening alloys |
| ferritic alloys | carbon（0.10-1.2%） +chromium （12-18%） | ++chromium（16%） +nickel（8%） | +chromium （19%） +molybdenum +small amount of nickel | +chromium +nickel +copper/or other elements |
Performance Characteristics
| alloy group | | work hardening rate | corrosion resistance | hardenable | ductility | high temperature resistance | low temperature resistance | weldability |

FAQ
What grades and finishes of stainless steel does MESCO supply?
MESCO supplies 304/304L, 316/316L, 321, 310S and 2205 duplex stainless steel in coil, sheet and tube form. Surface finishes include 2B, BA, 8K mirror, brushed, embossed and color decorative finishes.
What is the difference between 304 and 316 stainless steel?
316 adds 2-3% molybdenum, which greatly improves pitting and crevice corrosion resistance. Choose 316 for marine, chemical and coastal environments; 304 is more economical for general indoor and decorative applications.
What sizes are available for stainless steel coil and sheet?
Thickness typically ranges from 0.3 mm to 100 mm with widths from 1000 mm to 2000 mm for coils, and custom sheet lengths are available. Send your specification and we will confirm the closest stocked or mill size.
What is the MOQ and delivery time?
MESCO keeps regular stock of popular 304/316 specifications with delivery in as fast as 3 days. Trial orders and mixed specifications are welcome - contact us for exact MOQ and lead time.
