Stainless steel flat bar products are created with a piece of steel, passing it through rollers to form it into coiled shapes, and reheating the material to shape it into a bar. Flat bar refers to any stainless steel material with square edges, most commonly in a rectangular shape.

Stainless steel is a popular material for a few different reasons. Stainless steel has a high resistance to corrosion because of the presence of chromium. Stainless steel can be in automotive parts, household appliances, cutlery, architectural components, brewing and distilling equipment, tankers, and surgical equipment, among other things.
Different steel alloys have different strengths and weaknesses. Some brands of stainless steel are resistant to high temperatures, while other alloys are best suited for cryogenic applications. When picking which alloy to use, be sure that it is the most suitable for the job.
Stainless steel is the material of choice when customers need high-strength materials that are resistant to corrosion. Stainless steel is easy to maintain and is known for its long lifespan, and the surface of stainless steel materials can be highly polished. Because of its low maintenance and long lifespan, it is the material of choice for long-term use.
303 stainless steel is similar to our 304 alloy, but can be free-machined, meaning that it can be cut with minimal effort. This maintains a polished finish and does not damage the tools. Because 303 is best suited for materials that need to be machined repeatedly, it is commonly used to create nuts, screws, gear, shafts, and aircraft fittings. To prevent the material from being damaged, it should only be used in mildly corrosive environments.
304 stainless steel is the most commonly used alloy on the market today. It is a non-magnetic steel which cannot be heat-treated but must instead be cold worked. One of the most common uses of 304 is in food processing, as the alloy is resistant to corrosive materials found in meat, fruit, and vegetables. 304 bars are commonly used as shafts and rods in engines, food processing equipment, and structural supports in corrosive environments.
304L stainless steel is similar to 304 but contains lower amounts of carbon, which reduces carbide precipitation during welding. This allows it to be welded in any state, even when the conditions would corrode the material. It is a general use alloy that is commonly used in engines and motors, food processing equipment, and pharmaceutical equipment. The mechanical properties are slightly lower than 304.
316 stainless steel is the second most commonly-used alloy after 304. It is among the corrosive-resistant alloys available today, and it is suited for marine applications. It has good durability and tensile strength. It is commonly used in food processing, chemical storage, oil refining equipment and medical applications.
