ASTM A312 Tp316L Welded Pipe & SS S31603 Tubes Manufacturer in India
Modifying the chemistry of alloys is often a common practice to bring about desired changes in the material. One such practice is lowering the carbon content in austenitic alloys such as Stainless Steel 316L Seamless Pipe. Being a molybdenum bearing alloy brings about several changes in the material. Firstly properties such as resistance to crevice corrosion and resistance to pitting are amplified in the UNS S31603 Stainless Steel Welded Pipe.

ASTM A312 Tp316L ERW Pipe
Second, the yield strength and tensile strength properties of alloy grade ss 316l pipe increases. The increase in yield strength is also due to the inclusion of nitrogen in the alloy of ASTM A312 TP 316L Seamless Pipes. Nitrogen also enhances the impact strength or toughness of the alloy. Adding nitrogen in low carbon alloys not only stabilizes them but also brings the mechanical strength of the Din 1.4436 Stainless Steel Pipe to grade 316, by compensating for the reduced content of carbon in the alloy. By reducing the content of carbon, manufacturers are able to produce a SS 316L Erw Pipe, which is easily weldable, without the alloy becoming susceptible to grain boundary precipitation. Hence, the problem of intergranular corrosion is simply eliminated. However, the issue with lowering the content of carbon in a 316l stainless steel schedule 80 pipe is that cannot be used at elevated temperatures.
