TP316L Seamless Stainless Steel Pipe

Stainless Steel 316 Pipe is an austenitic stainless steel grade pipe that has good resistance to chloride ion corrosion stress cracking. For this reason, the pipe is used in marine and sea water applications with ease. Zhejiang Xintongda Special Steel Manufacturing Co.,Ltd is a leading supplier and manufacturer of the Stainless Steel 316 Pipe products in various scales and dimensions.

316L stainless steel, also known as UNS S31603, is a low-carbon variant of 316 stainless steel. Let’s explore its properties, applications, and uses in various industries:

1. Medical Equipment and Surgical Instruments:
• 316L is widely used in medical devices and surgical instruments due to its excellent corrosion resistance and biocompatibility. It won’t corrode from exposure to bodily fluids or sterilization processes.
2. Kitchenware and Food Processing:
• Pots, pans, and other kitchen utensils are often made from 316L stainless steel. Its resistance to corrosion from food and liquids makes it ideal for food preparation and storage.
• In the food processing industry, 316L is used for equipment like tanks, conveyors, and mixing vessels.
3. Marine Applications:
• 316L is highly resistant to saltwater and harsh marine environments. It’s commonly used for boat fittings, marine hardware, and underwater structures.
• Its corrosion resistance ensures longevity even in aggressive saltwater conditions.
4. Pharmaceutical Industry:
• 316L is employed in pharmaceutical manufacturing equipment, including reactors, storage tanks, and piping systems.
• Its smooth surface finish and resistance to corrosion make it suitable for maintaining hygiene and sterility.
5. Chemical Processing:
• In chemical plants, 316L is used for valves, pumps, and process equipment. Its resistance to acids, alkalis, and corrosive chemicals is crucial.
• It performs well in aggressive environments where corrosion resistance is paramount.
6. Jewelry and Fashion Accessories:
• Due to its aesthetic appeal, 316L stainless steel is used in jewelry, watches, and fashion accessories.
• Its durability and resistance to tarnishing make it a popular choice.
7. Heat Exchangers and Evaporators:
• 316L is employed in heat exchangers, evaporators, and condensers due to its thermal conductivity and corrosion resistance.
• It withstands high temperatures and aggressive media.
8. Textile and Paper Processing:
• In textile dyeing and paper mills, 316L is used for dye vats, rollers, and other equipment.
• Its resistance to chemicals and high temperatures ensures reliable performance.

Remember that 316L stainless steel offers a balance of mechanical properties, corrosion resistance, and ease of fabrication. It’s a versatile material used across diverse industries!

Good oxidation resistance in intermittent service to 870°C and in continuous service to 925°C. Continuous use of 316 in the 425-860°C range is not recommended if subsequent aqueous corrosion resistance is important.

Grade 316L is more resistant to carbide precipitation and can be used in the above temperature range.

Grade 316H has higher strength at elevated temperatures and is sometimes used for structural and pressure-containing applications at temperatures above about 500°C.

316L stainless steel can be hot worked using most common hot working techniques. Optimal hot working temperatures should be in the range 1150-1260°C, and certainly should not be less than 930°C. Post work annealing should be carried out to induce maximum corrosion resistance.

Most common cold working operations such as shearing, drawing and stamping can be performed on 316L stainless steel. Post work annealing should be carried out to remove internal stresses.
