Semih Metals is a leading manufacturer and supplier based in Istanbul Turkey, known for its premium-quality Stainless Steel 321 Square Bars and Rods. The Stainless Steel 321 Square Bars and Rods are used in various industries such as chemical processing, aerospace, and power generation, among others, for their excellent strength, durability, and resistance to high temperatures and corrosion. Backed by our state-of-the-art facilities and a commitment to excellence, we deliver precision-engineered solutions tailored to meet your specific needs. With our focus on reliability, quick delivery, and superior customer service, we at Semih Metals have become the preferred choice for Stainless Steel 321 products in the Turkey and beyond.
Stainless Steel 321 Square Bars and Rods consist of an austenitic stainless steel alloy content of 17-19% chromium, 9-12% nickel, and 0.8-1.2% titanium to ensure excellent corrosion resistance and high-temperature strength. Bars can be expected to have tensile strength that is around 515 MPa, yield strength about 205 MPa, and elongation of 40%, thereby ensuring sufficient toughness even at cryogenic temperatures. SS 321 is highly resistant to oxidation and intergranular corrosion, thereby suitable for applications at high temperature. It has good formability and weldability and excellent creep and stress rupture properties, ideal for aerospace, chemical, and food industries.

Stainless Steel 321 Square Bars are available in a range of sizes, typically from ¼" to 12" in width. Common finishes include mill finish, polished, and cold drawn.
Yes, Stainless Steel 321 Square Rods can be welded using most standard welding techniques. However, post-weld heat treatment may be required to maintain its properties and prevent sensitization.
Stainless Steel 321 Square Bars are generally non-magnetic in their annealed condition. However, they may exhibit slight magnetic properties if cold-worked.
Stainless Steel 321 Square Bars and Rods are widely used in industries requiring excellent resistance to intergranular corrosion and high-temperature strength. They are suitable for applications in chemical processing, oil and gas, and heat exchangers due to their stability in harsh environments. In aerospace, they are used in exhaust systems and turbine engine parts. The material can find applications for such furnace parts as thermal oxidisers and expansion couplings where endurance to oxidation has to be accompanied by great heat resistance. All these bars and rods have sanitary equipment in food processing industries along with their architectonic uses being based on looks and sturdiness.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
