ASTM 321 TP321 321 H Stainless Steel Tube

Packing

Huien Metal will use the best quality of Packing , because its play important role especially in a case of international shipments in which consignment pass through various channels to reach the ultimate destination, so Huien Metal put extraordinary concern regarding packaging.

Huien Metal pack the 321 Stainless Steel Tube in numerous ways based on the products.

Testing Quality

321 stainless steel is tested by spectrometers or chemical instruments.

321 belongs to American standard titanium austenitic stainless steel, according to ASTM A240/A240M-19

The performance of 321 stainless steel is very similar to that of 304, but because of the addition of titanium metal, it has better resistance to grain boundary corrosion and high temperature strength. Due to the addition of titanium metal, it effectively controls the formation of chromium carbide.

321 Stainless steel industry applications:

Applied to grain boundary corrosion resistance of high chemical, coal, petroleum industry field machine, building materials heat resistant parts and heat treatment of difficult parts

✅Oil exhaust gas combustion pipeline

✅Engine exhaust pipe

✅Boiler shell, heat exchanger, heating furnace components

✅Muffler parts for diesel engines

✅Boiler pressure vessel

✅Chemical trucks

✅Expansion joints

✅Spiral welded pipe for furnace pipe and dryer
