Alpha Overseas(AOS) manufactures and trades SS 321 Pipes and Tubes, where thoroughgoing steadying is proficient by hardening in the range of 1750 Deg F and 1850 Deg F. The carbon content in 321 Stainless Steel Tubes is further involved to Titanium content and as a result it leaves content of chromium unaided. Alloy 321 Seamless Tubes is as well beneficial for soaring heat service for the reason that of its excellent properties of mechanical. SS 321 Tubes is same as Stainless Steel 304 but by means of titanium accumulation of no less than 5 times the content of carbon. Stainless Steel 321 Welded Tubes is not allied to fuse deterioration (inter - granular deterioration) when bare to slightly harsh atmospheres. Yet more operative method in contradiction of carbide precipitation is the accumulation of Titanium content to 321 Stainless Steel Round Pipes is to steady it. Type 321 Welded Pipes shows excellent corrosion resistance at high heats has exceptional confrontation to inter - granular erosion and has outstanding weldability.
