Despite the market having a variety of stainless steel grades, the price of those alloys is higher. The viability of employing these alloys enters the picture for some applications. Welded pipes made of grade 201 stainless steel are required for these applications. This particular grade has some of the lowest prices on the market. Due to the SS 201 Welded Pipe's much reduced nickel concentration, the alloy is less expensive.

Several stainless steel alloys get improved corrosion resistant qualities when nickel is added. The chemistry of the Stainless Steel 201 Welded Pipe was altered by the inclusion of higher amounts of manganese and nitrogen due to the absence of a higher content of nickel. Manganese and nitrogen both boost the hardenability and yield strength of Astm A358 Tp 201 Efw Pipe that contains little to no nickel.

Astm A312 Uns S20100 Erw Pipe is preferred for applications that call for high levels of toughness with little to no corrosion resistance qualities. This material is typically used a lot in settings when it is cold outside. The Din 1.4436 Rectangular Pipe retains its hardness in cold environments, unlike certain standard alloys that become brittle and shatter. Another functional area that makes use of the Asme Sa312 Tp 201 Square Pipe is structural piping systems. The austenitic stainless steel grade 301 and sus 201 schedule 40 pipe both have good formability, corrosion resistance, and fabricability.
