Piyush steel is a prominent manufacturer, supplier and exporter of high quality AISI 321 Stainless Steel Round Bars. These round bars are alloyed for typical high strength. These bars offer assured maximum yield strength with the addition of specific elements. These bars offer great impact strength, high strength, and more toughness. These bars are used for slightly stress relieving conditions. The stainless steel bars are offered in quenched and tempered conditions. These are designed to provide higher welding and bending properties. Other attributes of round bars are high strength, durability, sturdy finish, and structural stability. We produce these bars from tested and qualified materials that offer durable structure, flawless design, and superior strength. We provide these bars in various standards, designations, specifications, and custom dimensions. These bars are ideal for use in high pressurized applications and critical applications. We also develop these bars in non-standard and altered dimensions for industrial critical applications. Moreover, the bars offer excellent resistance to general and local corrosion. SS bars also offer service in the environments that contain a high level of chlorides and halides. It also offers good service in the pitting and crevices corrosive environments. Because of higher thermal stability, these bars offer good service at high temperatures without any deflection. It also offers great service in the atmospheric corrosive environments.

General properties of AISI 321 Stainless Steel Round Bars-
Stainless steel 321 is titanium stabilized with good corrosion resistance properties. These bars have excellent resistance to intergranular corrosion attacks even in the exposure to temperatures in the chromium carbide precipitation range of 427 deg C to 816 deg C. This alloy has excellent oxidation resistance up to 816 deg C. moreover, it has higher creep and stress rupture properties compare to standard grades. These bars also posses good low temperatures properties even in down toughness. These are bars are made with lower and higher carbon variants. These are developed for the improved creep resistance for higher temperatures above 1000 deg F. In most cases the carbon content of bars allows dual certification. AISI 321 Stainless Steel Round Bars are used in most of the dilute organic acids containing environments at moderate temperatures. Also, it performs well in pure phosphoric acids at down temperatures. It serves good performance in dilute solutions even at higher temperatures. These bars can also be used in fluoride and chloride free solutions at nominal temperatures. The bars do not perform well even in small concentrations of sulfuric acids.
Quality control measures-
Here at Piyush steel, we have applied strict quality control measures in every step of the fabrication process which ensures the product quality compliance of national and international standards. We have done a lot of hard work with full dedications, result from us in getting ISO certifications. We offer products with uncompromising quality under the set industrial norms.
