UNS S32615 Tube is a super austenitic stainless steel grade with a very high content of silicon for particularly corrosive conditions in an aggressive atmosphere. S32615 SX stainless steel tubing provides very high corrosion resistance to attack of the acid,oxidation and other severe crevice and pit corrosion. Our ASTM A213 UNS S32615 and ASTM A959 UNS S32615 stainless steel standard tubes are employed in sulfuric acid manufacture, heat exchangers, instrumentation, chemical process equipment, acid cooler tubing, and etc.

Trusted UNS S32615 Tube Manufacturer and Supplier

We are a leading UNS S32615 tube manufacturer and a global distributor of high-quality tubing for demanding industrial applications. We offer a variety of products such as seamless tubes, welded tubes, heat exchanger tubes, condenser tubes, instrumentation tubing and custom fabricated tubing products, all produced in accordance with international quality standards.

High Silicon Austenitic Stainless Steel Tube has unique chemical composition which gives it exceptional resistance against concentrated sulfuric acid which makes it the preferred choice across chemical processing industries. In highly corrosive applications, S32615 SX stainless steel tubing provides improved durability, longer service life and lower maintenance costs compared to conventional stainless steels.

We control our manufacturing processes to assure that each tube meets the demanding dimensional tolerances, mechanical requirements and corrosion resistance standards of today’s industries.

What is UNS S32615 Tube?

UNS S32615 Tube is an upgraded high-silicon austenitic stainless steel tube which resists concentrated sulphuric acid better. Being extremely high in silicon and chromium than normal stainless steels makes them better in facing attacks of acid and thus offering greater safety.

Some applications of this specialty are:

• Sulfuric acid coolers
• Heat exchangers
• Chemical processing plants
• Pickling systems
• Acid storage facilities
• Fertilizer manufacturing plants
• Instrumentation and control systems

With superior resistance to concentrated sulphur acid across the entire range of temperature, sulfuric acid cooler tubes UNS S32615 find their major role where normal stainless steels might have premature failure.

Properties of High Silicon Austenitic Stainless Steel Tube

Sulfuric Acid Resistant: A high content silicon austenitic steel may form passivity and resist strong acid sulfuric acid.

Comprehensive corrosion: Provides outstanding protection against:

• Uniform corrosion
• Pitting corrosion
• Crevice corrosion
• Intergranular corrosion
• Oxidation

High Temperature Performance: It has high strength and strong corrosion resistance at high temperature.

Long Service Life: Reduce the overall operating costs, reduce the need for routine maintenance and delay the renewal period of equipment.

Good Fabricability: Can be fabricated into seamless and welded tubing configurations suitable for various industrial applications.

Superior Process Reliability: Ideal for critical chemical processing systems where downtime is costly.
