ASTM A312 TP 304 erw Tube and SS 304 Pipe Suppliers in India


One of the most common alloy grades, stainless steel 304 is an austenitic alloy. This means the alloy of stainless steel 304 seamless pipe possesses austenite as their principle crystalline structure. Austenite is also referred to as a gamma-phase iron, the presence of which makes the 304 Stainless Steel Pipe non-magnetic properties.

Grade 304, is also referred to as 18/8 or A2 or SUS304 or UNS S30400 by SS 304 Pipe Suppliers in Mumbai and stainless steel 304 pipe manufacturers in India. In comparison to most carbon steels, the thermal conductivity and electrical conductivity of this alloy are low. Yet the corrosion resistance properties of grade 304 stainless steel exhaust pipe tends to be significantly higher in comparison to carbon steels, particularly due to the addition of elements in its alloy. The constitution of grade 304 consists of both chromium and nickel. By adding nickel to austenitic stainless steel 304 pipe, the austenite in the microstructure of the alloy gets stabilized. Nickel also imparts the alloy with several interesting characteristics. For instance, the yield strength, resistance to oxidation, and impact strength or hardness properties of astm a312 tp 304 welded pipe see a significant increase, in comparison to carbon steels at both low temperatures as well as elevated temperatures. The resistance to oxidation is further improved by the high content of chromium in the alloy of ss 304 seamless pipe, due to the formation of a passivated oxide layer.
