321 Stainless Steel Round Bar

Sanjivini Steel Center is a leading manufacturer, supplier, and exporter of stainless steel 321 round bar in India. Grade 321 stainless steel is a member of the austenitic class 300 series of stainless steel. Like most stainless steel alloys in the 300 series, the JIS SUS 321 black bar has certain mechanical and corrosion-resistant properties. The primary difference between grade 304 and alloy 321 stainless steel round bar is that titanium has been added to stabilize the alloy. Titanium is a useful additive to any alloy, particularly when welding is necessary.

As opposed to carbide precipitation, titanium carbides are formed on the weld seam during the welding process and are rather stable. Because of this, alloy 321 stainless steel rods are more resistant to intergranular corrosion and do not experience sensitization at the grain boundary. When exposed to exceptionally high temperatures, the ASTM A276 type 321 flat bar’s mechanical qualities are further enhanced by the titanium addition. The alloy maintains its same yield strength and impact resistance. The fact that grade 304 and the ASTM A479 UNS S32100 hex bar both function exceptionally well even in cryogenic settings is another similarity between them.

Good mechanical qualities and impact strength are essential for alloys used in cryogenic applications. By alloying metals like chromium and nickel with lower amounts of manganese and titanium, DIN 1.4541 square bar is produced that meets all requirements. However, the material’s better creep strength at high temperatures is the primary factor that influences customers’ decisions to utilize AISI 321 threaded bars for their applications. Grade SS 321 bright bar can survive and function well at temperatures like this, while alloys like 304 are prone to failing.
