SA312 Tp304L Welded Pipe & SS UNS S30403 Tubing Manufacturer in India


Lowering the carbon content of any austenitic stainless steel effectively enhances the weldability of the material. Low carbon variety Stainless Steel 304L Seamless Pipe mentions the letter L, as an indicator of its modified chemistry. In steels that contain a higher degree of the element carbon, the chances of sensitization at the grain boundary is substantially higher.

Thus, leaving the material vulnerable to intergranular corrosion. The reduction of carbon content in the alloy of Stainless Steel 304L Pipe would mean that there is no free carbon present on its surface and the rate of corrosion automatically decreases. Any modification in the chemistry of its alloy would either weaken or strengthen the material. In the case of 304, lowering its carbon content would typically yield a low mechanical strength 304l schedule 10 stainless steel pipe. However, manufacturers of these pipes often add trace amounts of nitrogen in their chemistry. This is another modification that distinguishes grade 304 and SS UNS S30403 ERW Pipe. By adding nitrogen to its alloy, the manufacturer is able to improve the mechanical strength of the ASTM A312 TP 304L Stainless Steel Pipe bringing it at par with grade 304. Therefore the mechanical strength, corrosion resistance as well as weldability properties of the 304l ss welded pipe are higher in comparison to carbon steels.  However, the cost of improved characteristics also leads to an increase in price, which is why the price of alloy 304l seamless stainless steel pipe is higher than carbon steels.
