304L Stainless Steel Flat Bar

Designed for use in tanks, enclosures, cabinets, housings, dairy, transportation, architectural, chemical and food processing industries.

Product Description

The 304L stainless steel flat bar is an austenitic metal that is made up of 18 percent chromium and 8 percent nickel. The carbon maximum for this grade of metal is 0.030 percent. This alloy is widely used because of its versatility. It is the most used stainless steel alloy in its family. 304L stainless steel is highly resistant to corrosion, even intergranular corrosion, which is caused by stress relieving or welding. Its low level of carbon makes it ideal for the majority of welded construction operations that use service temperatures that are limited to 800 degrees F. To make this metal harder and stronger, heat treatment can’t be used. Cold working should be done instead, which will cause slight magnetism.

Applications that 304L alloys are commonly used in include food processing equipment, kitchen benches, kitchen troughs, automotive and aerospace equipment, chemical containers, dying industry, heat exchangers, architectural molding, and welded screens for water filtration.

The 304L stainless steel flat bar shows resistance to corrosion when placed in environments that are oxidizing, due to the chromium content. The nickel it is alloyed with helps it to resist organic acids that are moderately aggressive. Compared to 304 alloys, 304L alloys sometimes show a lower rate of corrosion. In other cases, it performs uniformly in these environments with 304 and 304H alloys. This metal is a preferred choice when it has to be placed in environments that are sufficiently corrosive and could possibly lead to intergranular corrosion and within heat-affected zones that most alloys are vulnerable in.
