Product Description

309S is a low-carbon variant of 309 stainless steel designed for applications requiring welding. The lower carbon content minimizes carbide precipitation in the heat-affected zone near the weld—precipitation that could otherwise lead to intergranular corrosion (weld decay) in certain environments. It withstands repeated heating at temperatures up to 980°C and exhibits high-temperature strength, as well as resistance to oxidation and carburization. It is widely used in critical sectors such as boilers, energy (nuclear, thermal, and fuel cells), industrial furnaces, incinerators, heating furnaces, and the chemical and petrochemical industries.

 

 

Stainless steel electroplated steel wire


Stainless steel electroplated wire can be used to manufacture various jewelry and decorative items, such as necklaces, bracelets, anklets, etc., as well as industrial tools and nets.

 

Bright-finish wire, electropolished wire, and hydrogen-annealed wire

 

Bright-finish wire, electropolished wire, and hydrogen-annealed wire are all textile materials, each with its own unique applications.

 

 

Titanium-plated stainless steel wire

Titanium-plated stainless steel wire is suitable for crafting high-end decorative items such as jewelry, watch bracelets, and ornamental chains, thanks to its corrosion resistance, high luster, and durability.

Stainless Steel Decorative Wire

Stainless steel decorative wire is primarily used to create various decorative items—such as ribbon-style ornaments and sequin-like accents—adding an artistic touch to residential and commercial spaces.

 

 

 

Stainless Steel Microwire

Stainless steel microwire is a small, flexible metal wire characterized by high strength and corrosion resistance.

These applications rely on 309S stainless steel wire.

1. In the field of chemical equipment: In reaction vessel pipelines and valve components exposed to strong acids and strong alkalis, welded parts made of Stainless Steel 309S Wire can effectively resist corrosion and extend the service life of the equipment.

2. For boilers and heat treatment equipment: The supports inside boilers and the connection wires of high-temperature furnaces, with the advantage of high-temperature resistance, avoid oxidation problems under high temperatures.

3. In the food and pharmaceutical industry: For conveyor chains in food processing plants and metal nets inside ovens, Precision-drawn 309 309S Hard Stainless Steel Wire Drawing Wire High-resilience, after coming into contact with high-temperature media, does not release harmful substances and complies with hygiene standards.
