ASTM A276 AISI STAINLESS STEEL 321 ROUND BAR is a titanium balanced out austenitic chromium-nickel hardened steel which was created to furnish a 18-8 type compound with improved intergranular-erosion obstruction. This material is settled against chromium carbide arrangement by the expansion of titanium.
Grade 321 stainless steel (1.4541) is a heat resistant grade supplied into numerous industry sectors. The key property of this grade is the added titanium content stabilizing the materials and making its strength to carbide precipitation when exposed to high temperatures and resistance to oxidation its main characteristics. For good strength and toughness when exposed to high temperatures, this grade of stainless steel like much austenitic grades will also maintain its strength and toughness at sub-zero temperatures, making this an excellent choice for different different applications ranges from crude oil refinery equipment to automotive exhaust systems.
