Product  Description

Stainless steel is a steel alloy with increased corrosion resistance compared to carbon/alloy steel.

Common alloying ingredients include chromium (usually at least 11%), nickel, or molybdenum. Alloy content often is on the order of 15-30%.

Common applications for stainless steel include food handling/processing, medical instruments, hardware, appliances, and structural/architectural uses.


With every batch, we guarantee the following advantages:


Low Carbon Content

Our 304 and 316 dull polished stainless sheet offerings have low carbon content. Therefore, they’re hugely useful in the construction and welding industries. While welding it, you’ll have zero carbide precipitation.


Rust Resistance

Our polished stainless steel sheet is hugely resistant to rust. For the food and manufacturing industries, rust resistance is a great advance. Our 304 stainless steel sheet won’t need to undergo annealing after welding it.

While they may not boast the same resistance to rust, we also stock copper sheets and brass sheets for varied needs.


Machinable

Thanks to the superior formability of our stainless steel sheet, users can stamp and deep draw it for varied applications.
