Stainless steel is a versatile  of piping and tubing. Stmaterial consisting of an alloy of steel and a small percentage of chromium — the addition of chromium adds to the corrosion resistance of the material, a feature that earned its name from stainless steel. Since stainless steel is also low-maintenance, oxidation-resistant and does not affect other metals it comes into contact with, it is often used in a wide range of applications, particularly in the manufactureainless steel piping is divided into several categories based on the end-use of the pipe.

Stainless Steel Pressure Tube: This type of stainless steel tubes is made from either solid chromium or a chromium and nickel combination. Types of pressure tubes include Stainless Steel Seamless Tubes and welded tubes, electric fusion welded tubes for high-pressure applications, large-diameter welded tubes for corrosive or high-temperature applications, and seamless and welded ferritic and austenitic stainless steel tube.

Stainless Steel Sanitary Tube: Sanitation is at high priority for applications where stainless steel tubing or piping has to come into contact with food and other sensitive materials. Stainless steel sanitary tubing is used in such applications as it is highly resistant to rust, does not tarnish, and is easy to maintain. Various tolerances can be achieved for specific applications. The grade typically used for these applications is ASTM A270.

Stainless Steel Mechanical Tube: In applications such as cylinders, bearings, and other hollow formed parts, stainless steel mechanical tubing is typically used. Tubing can be manipulated to have a variety of cross-sectional shapes, such as square and rectangular, in addition to the more traditional, round tubing cross-section. ASTM grades A511 and A554 are usually used for mechanical tubing.
