316 Stainless Steel Square Tubing

316 stainless steel square tubing is made of high-quality 316 stainless steel material, which has excellent corrosion resistance and durability. The square tubing is widely used in various industries, including construction, machinery, and transportation.

 

The specification of 316 stainless steel square tubing is usually measured by its outer diameter, thickness, and length. The standard size ranges from 1/2 inch to 12 inches in diameter, with a wall thickness varying between 0.065 inches and 0.50 inches. The length can be customized according to the customer's requirements, with the maximum length being 24 feet.

 

To produce 316 stainless steel square tubing, the first step is to make a round tube of the desired diameter and thickness through the welding process. The round tube is then straightened, annealed, and cut into the required length to form a square tube. The final step involves polishing and/or grinding the tube to achieve a smooth and clean surface finish.

 

The seamless square tubing process typically involves rolling hot-rolled steel and then cold-drawing it to the final size. The welded square tubing method uses an electric resistance welding process, which is more cost-effective.

 

316 stainless steel square tubing is commonly used in the construction of structures such as railings, fencing, and balconies. Other applications include use in the chemical and petrochemical industries, medical equipment, and marine environments.

 

The technical parameters of 316 stainless steel square tubing include its yield strength, ultimate tensile strength, elongation, and hardness. It is recommended that users follow safety regulations when handling or using the tubing.

 

 

 

 

 

Product description
International stainless steel marking method
The American Iron and Steel Institute uses three digits to mark various standard grades of malleable stainless steel. Including:
① Austenitic stainless steels are marked with 200 and 300 series of numbers. For example, some common austenitic stainless steels are marked with 201, 304, 316 and 310.
② Ferritic and martensitic stainless steels are represented by 400 series numbers.
③ Ferritic stainless steel is marked with 430 and 446, and martensitic stainless steel is marked with 410, 420 and 440C.
④ Duplex (austenite ferrite), stainless steel, precipitation hardening stainless steel and high alloy with iron content less than 50% are usually named by patent or trademark.
