40mm Width x 3mm Thick Flat Bar Stainless Steel Metal Strip

304 Grade Metal Strip

Top quality flat bar stainless steel metal strip supplied straight from Warrington, UK. As the name suggests, stainless steel flat bar is essentially pre-fabricated stainless steel strips.

We stock a significant amount of stainless steel flat bar that is slit and edge-rolled. Stainless steel plate is slit into bars, and the edges are treated (rolled) to remove sharp burrs. There is the possibility that the slitting process can result in the finished bar having two non-straight faces (on the thickness dimension). When the bar is machined to size, the squareness of the section may not be as important, but if it is not, the hot rolled bar may be a better option. We will slit and edge roll all strips that are 3mm, 5mm, 6mm, and 8mm thick.

Its smooth surface makes it ideal for polishing, which is one of its major advantages.

We source stainless steel metal strip from accredited mills.

What Is 304 Grade Flat Bar?

The stainless steel grades 304 and 304L are alternatively referred to as 1.4301 and 1.4307.

There is no doubt that type 304 is the most versatile and widely used stainless steel. In technical literature, it is still sometimes called 18/8, which is derived from its nominal composition, 18% chrome, and 8% nickel, and is often confused with the modern term stainless steel.

As austenitic steel, type 304 stainless steel can be greatly deep drawn. It is due to these properties that 304 is the most frequently used steel grade in applications in the kitchen.

• Bendability – Good
• Tensile Strength -Excellent
• Cold Working – Good
• Corrosion Resistance – Excellent 
• Heat Resistance – Good
• Heat Treatment – Poor
• Hot Working – Fair
• Machinability – Good
• Weldability – Very Good

How Long Will The Stainless Steel Metal Strip Last?

It is important to note that the longevity of 304-grade stainless steel strip is largely determined by the environment in which it is used. In spite of this, stainless steel of 304 grade can last many decades under normal conditions and with proper care as long as it is properly maintained.

There is a type of stainless steel that is known for its high corrosion resistance, which makes it particularly durable with regard to various forms of wear, such as rusting. The robust properties of this material make it a popular choice for a wide range of applications in various industries, such as construction, automotive, and kitchenware, to name a few.

Nevertheless, the actual lifespan will also depend on factors like exposure to corrosive chemicals, mechanical stress, and extreme temperatures. Regular maintenance and proper installation can also help to extend the lifespan of the stainless steel strip.

Can I Use This Metal Strip Outdoors?

Yes, stainless steel is resistant to weathering and corrosion, making it suitable for outdoor applications.

For example, 304-grade stainless steel is generally a better choice for outdoor applications compared to mild steel. This is primarily due to its superior resistance to corrosion.

Although mild steel is strong and durable, it does not have the same level of resistance to the elements that stainless steel does. Mild steel can oxidize and form rust over time when subjected to moisture and oxygen – conditions usually encountered outside, where mild steel is exposed to moisture and oxygen – which, in turn, can degrade its structural integrity over time.

304-grade stainless steel, on the other hand, has a high chromium content, which produces a passive layer of chromium oxide on the surface of the steel. In order to protect the underlying metal from corrosion and other forms of wear, this layer is extremely resistant to corrosion. In contrast to mild steel, stainless steel tends to have a longer lifespan and requires less maintenance when used outdoors compared to mild steel due to its corrosion-resistant properties.
