This addition in Stainless Steel 321 Square Bars is made to reduce or eliminate chromium carbide precipitation – resulting from welding or exposure to high temperatures. Stainless Steel 321H Square Bars are used because they are not sensitive to inter-granular corrosion after heating within the carbide precipitation range of 425°C – 850°C. SS 321 Square Bars is also advantageous for high temperature service because of its good mechanical properties. SS 321H Square Bars is similar to SS 304 Square Bars but with a titanium addition of at least five times the carbon content. Since titanium in Alloy 321 Square Bars has a stronger affinity for carbon than chromium, titanium carbide precipitates within the grains instead of forming at the grain boundaries.

Alloy 321H Square Bars also improves the elevated temperature properties of the alloy. Our 321 Stainless SS Square Bars is a heat resistant grade supplied into numerous industry sectors. Characterized by high corrosion resistance in general atmospheric corrosive environments, these 321H Stainless SS Square Bars exhibits excellent resistance to most oxidizing agents, sterilizing solutions, general foodstuffs, dyestuffs, most organic chemicals plus a wide variety of inorganic chemicals, also steam combustion gases, hot petroleum gases, nitric acid, and to a lesser extent sulfuric acid.

Stainless Steel 321 is a typical type of authentic metal which is identical to SS 304, but with additions of titanium and five times the carbon content. Due to the content of carbon in this high steel alloy it reduces the risk of carbide precipitation during welding. This high steel alloy furnishes excellent resistance to corrosion and oxidation. SS 321 can be utilized for high temperature services because of its good mechanical properties. It also posses good creep and stress rupture properties than SS 304. The high steel alloy offers identical resistance to overall corrosion due to high nickel and chromium content. 

What is Stainless steel 321 Square Bar?
