We pride ourselves on delivering top-notch stainless steel products that excel in tough, corrosive, and high-stress environments. Our bars are crafted using cutting-edge techniques and strict quality standards, ensuring they offer outstanding durability, strength, and precision. With their remarkable resistance to chemical attacks and oxidation, these Stainless Steel 317 Rectangular Bars are perfect for various industries, including chemical processing, pulp and paper, marine, and petrochemical sectors. At Isis Metals, we’re committed to providing high-grade stainless steel materials tailored to meet your industrial and structural needs.
Stainless Steel 317 Rectangular Bars are made from high-alloy austenitic steels, featuring chromium (18–20%), nickel (11–15%), and molybdenum (3–4%) to boost their corrosion and pitting resistance. They showcase impressive tensile strength of about 515 MPa and yield strength around 205 MPa, along with good ductility and toughness. This alloy is particularly resistant to sulfuric acid, chlorides, and other harsh chemicals. Its mechanical stability at high temperatures and excellent weldability make it a go-to choice for demanding industrial applications that require both corrosion and heat resistance.

Stainless Steel 317 Rectangular Bars generally offer excellent corrosion resistance due to their alloy composition, but additional protective coatings may be beneficial in highly aggressive environments. For most applications, coatings are not necessary unless exposed to extreme conditions.
Choose Stainless Steel 317 Rectangular Bars based on factors like required corrosion resistance, strength, and the specific environmental conditions. Ensure the dimensions and grades meet the mechanical and chemical requirements of your application.
Yes, Stainless Steel 317 Rectangular Bars can be welded using standard welding techniques like TIG and MIG. However, proper heat control is essential to prevent carbide precipitation and maintain corrosion resistance.
You’ll find Stainless Steel 317 Rectangular Bars in a variety of settings where high corrosion resistance and strength are essential. They’re commonly used in chemical and petrochemical processing equipment, heat exchangers, machinery in the paper and pulp industry, and components in marine engineering. These bars are also ideal for pollution control systems, condensers, and evaporators, where they often face harsh chemicals and high temperatures. Their outstanding mechanical performance and resistance to pitting make them perfect for structural and fabrication applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
