A square bar is a stainless steel bar with four equilateral sides. Steel square bar products are produced by heating a square section of steel, passing it through rollers, and then reheating the material to shape it into a square.
Because of the high strength and durability of stainless steel, stainless steel square bar is a popular and effective choice for many industrial tasks. Stainless steel bar products are used in industries including food processing, chemical processing, brewing, heat treatment, construction and architecture, and pharmaceutical equipment. They are also used in creating furniture.
Different alloys of steel are suited to specific tasks. While most stainless steel alloys are resistant to corrosion, some alloys are better suited to marine tasks. Certain alloys resist high temperatures, while others are better suited to cold temperatures. Choose the most appropriate alloy for a given task.
Stainless steel is the material of choice when customers need high-strength materials that are resistant to corrosion. Stainless steel has one of the greatest tensile strengths on the market and is easy to maintain. All stainless steel alloys are highly durable and resistant to damage, meaning that they can be used in high-intensity settings.
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. The different chemical composition from 304 does reduce the corrosion-resistance of the material. 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. Its corrosion resistance is lower than other steel alloys.
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. It has good tensile strength, corrosion resistance and durability. 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. It should not be welded.
316 stainless steel is the second most commonly-used alloy after 304. It is among the corrosive-resistant alloys available today, and it is best-suited for marine applications. It is commonly used in food processing, chemical storage, oil refining equipment and medical applications. It is not indicated for welding in normal circumstances.
316L stainless steel has lower-than-normal amounts of carbon, which prevents carbide precipitation. 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 316.
