SS316L Stainless Steel Metal Pipe AISI 40MM Astm A554 Square Tube
Cutting
Once the steel is worked and ready, the batch is cut to fit order requirements.
The most common methods are mechanical methods, such as cutting with guillotine knives, circular knives, high-speed blades or punching with dies.
However, for complex shapes, flame cutting or plasma jet cutting may be used as well.
The best option will depend on both the grade of steel requested and the desired shape of the delivered product.
Finishing
Stainless steel is available in a variety of finishes from matte to mirror. Finishing is one of the last steps involved in the manufacturing process. Common techniques include acid or sand etching, sand blasting, belt grinding, belt buffing and belt polishing.
At this point, the steel is gathered in its final form and readied for shipping to the customer. Rolls and coils are common ways to both store and ship large quantities of stainless for use in other manufacturing processes. However, the final form will depend on the type of steel required and other factors specific to the order.
Understanding the proper stainless steel grades and types for specific uses and environments is an essential part of ensuring long-lasting results and optimizing costs. Whether you’re looking for something strong and corrosion-resistant for marine environments or something stunning and easy to clean for restaurant use, there’s a stainless steel alloy available to suit your needs.
