Description

Manufacturers & Suppliers of Stainless Steel 321/321H Seamless Pipes , UNS S32100/S32109,1.4541/1.4878 Seamless Pipes

Metline is a leading manufacturer and supplier of SS 321/321H seamless pipes. Our seamless 321/321H pipes are manufactured in a variety of size and schedule or thicknesses. However, there is a restriction on the manufacturing of large diameter pipe. Generally, seamless 321/321H pipes are available in stock in sizes upto 16″. Seamless pipe, as the name suggests, is a pipe without a seam or a weld-joint. Seamless 321/321H stainless steel pipe is made from a solid round steel ‘billet’ which is heated and pushed or pulled over a form until the steel is shaped into a hollow pipe.

About 321/321H Stainless Steel

Stainless Steel 321 is a basic austenitic 18/8 steel (Grade 304) stabilised by Titanium (321) addition. SS 321 is used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C. Stainless Steel 321 is the grade of choice for applications in the temperature range of up to about 900°C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion. SS 321H is a modification of SS 321 with a higher carbon content, to provide improved high temperature strength.

  • 321H also shows resistance against acid corrosion in a variety of environments.
  • Lower temperatures provide better resistance, but the metal is able to withstand up to a 10% acid solution
  • 321 stainless steels show very little resistance against chlorine or sulfuric solutions at any given temperature.
