SS 321 Hex & SS 321 Square Bars
Royal Metals is a leading stockists of Stainless Steel 321 Hex & SS 321 Square Bars in Coimbatore. SS 321 is a kind of Ni-Cr-Ti austenitic stainless steel, with good wear resistance. AISI 321 is also a refractory steel with better high temperature resistance than 316L. Its performance is very similar to that of 321, but since Ti is added as the stabilizing element, 321 stainless steel features better high temperature strength and inter granular corrosion resistance, and it can effectively control the formation of chromium carbide as a result. We deal in Stainless Steel 321 Bright Bars, Stainless Steel Black Bars, Stainless Steel 321h Hex & SS 321 Square Bars, Stainless Steel Hex Bars, Stainless Steel Square Bars, Stainless Steel Forged Bars, Stainless Steel Angles, Stainless Steel Channel. Royal Metals supplies a wide range of stainless steel Hex & SS 321 Square bars & rods at both home and abroad. The supply of our SS Hex & SS 321 Square bars & rods comes with multiple sizes and various grades which are both customizable.
