Our 309s stainless steel coil is a commonly used and widely applied stainless steel material, offering numerous advantages.

  1. High Temperature Resistance: One of the primary advantages of 309S stainless steel is its exceptional resistance to high temperatures. It can withstand temperatures up to 980°C (1800°F) without significant deformation or loss of mechanical properties. This makes it suitable for applications in heat treatment, furnace components, and other high-temperature environments.

  2. Oxidation Resistance: 309S stainless steel exhibits excellent oxidation resistance, making it resistant to scaling and the formation of oxide layers at high temperatures. This property allows it to maintain its structural integrity and performance in oxidizing environments.

  3. Corrosion Resistance: 309S stainless steel offers good resistance to corrosion, particularly in mildly corrosive environments. It can withstand exposure to atmospheric conditions, certain acids, and alkalis, making it suitable for various industrial and chemical applications.

  4. High Strength: 309S stainless steel has high tensile strength and good toughness, providing excellent structural integrity and resistance to deformation. It can withstand heavy loads and is less prone to breakage or failure.

Automotive Industry

309S stainless steel is used in automotive exhaust systems due to its high-temperature resistance and corrosion resistance. It can withstand the extreme heat and corrosive gases produced by the engine, ensuring durability and longevity.

Aerospace Applications

The high strength and heat resistance of 309s stainless steel make it suitable for aerospace applications. It is used in aircraft components, such as engine parts, landing gear, and structural elements.

Industrial Equipment

This stainless steel grade is also used in various industrial equipment, such as storage tanks, chemical processing equipment, and machinery components. Its corrosion resistance and strength make it suitable for demanding industrial environments.

Medical Equipment

309s stainless steel is utilized in medical equipment due to its corrosion resistance and biocompatibility. It is suitable for use in surgical instruments, orthopedic implants, and other medical devices.


Q: How can I pay my order?

A: We accept T/T, Western Union,Alibaba Online Payment to pay.

Q: Do you have any certificate?

A: We have passed ISO9001:2008,ISO14001OHSAS18001 and obtained CE certificate and BSCI certificate from UL.

Q: Why the model name of your machine same as the machine form other company?

A: Since these machines have long history and are very popular in the market, it may be indeed possible that some machine models are similar as others. What we may think is that the machine model does not make big difference. And the criteria for machines may depend on the technical support and quality of the machines.

Q: How about your warranty?

A: Our warranty is 12 months. Normally,the general after-sale service may be as below.

1) The technical support is permanent.

2) The paid spares parts could be provided at any time,

3) We have dealers in some countries to offer compensable service.
