SS 321h Square Bars & ASTM A276 Type 321 Rod Manufacturer in India


In addition to being used for applications such as Chemical Processing, Food Processing, Waste Treatment & in Aerospace, austenitic stainless steel may able be used in Petroleum Refining industries. In petroleum refineries, the equipment used to refine petroleum may become susceptible to PASCC. Essentially, PASCC, or as known as Polythionic Acid Stress Corrosion Cracking is a kind of intergranular stress corrosion.

PASCC is a condition that affects sensitized stainless steel alloys, particularly those alloys used in petroleum refineries, where the application is to process feedstocks that contain sulfur. This damage mechanism of PASCC primarily affects the conventionally used and high carbon stainless steel. Although low carbon and chemically stabilized alloys such as the ASME SA276 Grade 321 ss Bar may be vulnerable to getting corroded, under some situations, compared to high carbon alloys, the chances of this happening are relatively lower. The UNS S32100 Forged Bar exhibits good general corrosion resistance rivaling that of stainless steel alloy 304. The alloy is able to withstand elevated temperatures because the 321 stainless steel square bar developed with the intention of being used between 1800 – 1500°F. This high temperature range is referred to as the in the chromium carbide precipitation range. The Stainless Steel 321 Round Bar is well suited for applications in most diluted organic acids at moderate temperatures as well as in 10% diluted solvents at raised temperatures. The 321 Stainless Steel Round Bar could be employed in pure phosphoric acid solutions at lower temperatures. Corrosive chemicals such as chloride or fluoride free caustic solutions have no effect on the SS 321 Rod at moderate temperatures. Though the alloy has decent corrosion resistance properties, the ASTM A276 type 321 SS Bar does not operate adequately in chloride solutions, even if the alloy has been exposed to small concentrations, or in sulfuric acid applications. Perfect Impex is one of the supplier who provide cut to length bar in all grade which saves extra cost. We are 321 Round Bar Supplier who stocks in all surface finish.
