Suppliers, Traders, Exporters and Stockists of Stainless Steel Grade 321 Round Bars & SS Rods
ARK Stainless is a leading supplier, trader, stockist and exporter of SS 321 round bars and rods. Grade 321 stainless steel belongs to the austenitic class 300 series. Like most of the 300 series stainless steel alloys, the JIS SUS 321 black bar has multiple mechanical and corrosion resistance properties.
The chemistry of this alloy is similar to grade 304, with the only difference that alloy 321 stainless steel round bar has been stabilized with the addition of titanium in its alloy. Adding titanium in any alloy is beneficial, particularly if the alloy has to undergo welding operations.
During welding, the titanium forms titanium carbides on the weld seam, which is comparatively stable as opposed to carbide precipitation. Hence, alloy 321 stainless steel rods have superior resistance to intergranular corrosion and their grain boundary does not undergo sensitization. The inclusion of titanium also improves the mechanical properties of the astm a276 type 321 flat bar, when subjected to extremely high temperatures. The yield strength and impact resistance of the alloy remains the same. Another common ground between grade 304 and the ASTM A479 UNS S32100 hex bar is that they deliver excellent performance even in cryogenic environments.
Alloys that are a part of cryogenic applications need to have a good impact strength and good mechanical properties, with the alloying of metals like chromium and nickel, the smaller amounts of manganese and titanium ensure that the DIN 1.4541 square bar used is up to the mark. Yet, the main reasons buyers choose to use AISI 321 threaded bar for their applications is that the material has superior creep strength at high temperatures. When alloys like 304 are susceptible to failing at such temperatures, grade ss 321 bright bar is able to thrive and have a lasting performance.
SS 321/321H Round Bars/Rods can be called as an austenitic steel bar. This is available in different sizes, shapes, and grades. It has a low carbon content that makes steel as an ideal raw material. Mostly steel contains a large amount of nickel and chromium. The mixture of nickel and chromium makes it susceptible to warmth treatment.
SS 321 is an austenitic grade of stainless steel. The Stainless Steel 321 Round Bar is designed with a chemical composition consisting of chromium and nickel with titanium acting as the stabilizing agent. The versatile 321 Stainless Steel Hollow Bar is produced by passing hot steel billets through them or welding them in place. These bars showcase excellent tolerance to corrosive reducers in volatile conditions. 1.4541 Forged Round Bar is manufactured via the forging process and showcases good impact strength, and is dimensionally accurate. The high-strength AMS 5510 Bar can function in temperatures ranging between 538 to 870 degrees C. Designed with a uniform cross-sectional area, the items can be easily welded in place following standard welding procedures. SS 321 Bar showcases a minimum tensile strength of 515mpa with a minimum yield strength of 205mpa. These bars can be easily elongated by 35% and still possess excellent workability. AISI 321 Stainless Steel Cold Rolled Bar is processed further after the initial stage to give it enhanced strength and superior surface finish. The non-pressurized ASTM A276 UNS S32100 Bar has a melting point of 1454 degrees C. These bars can be customized in an array of shapes and sizes to meet different project requirements.
The ASTM A276 SS 321h Rod is a higher carbon version grade that is designed with superior strength. This allows it to provide good support and stability than normal SS321 grade rods; however, their welding performance is very low. 321H Stainless Steel Rectangle Bar is designed with a rectangular cross sectional area. The flat bars are lightweight and are used in different structural applications. The SS 321H Black Bar is a type of finish that adds an aesthetical appeal to the grade. These bars are generally utilized in applications where the shape and tolerance requirements are not precise. For more information on the products, contact us for more information.
