Description

Manufacturers & Suppliers of Stainless Steel 321 Tubes, UNS S32100/1.44541 Seamless & Welded Tubes

Metline is a specialist manufacturer and supplier of 321 stainless steel tubes with Bright Annealing (BA Tube) or Polishing (Surface Roughness Ra 0.18). We produce 321 stainless steel tubes outside diameter 6mm upto 5″, in wall thickness upto 10mm. Metline is a professional producer of both thin wall and thick wall stainless steel tubes, with exports to over 70 countries across the globe. In addition to 321 stainless steel tubes, we can also produce and supply related tube fittings such as ferrule fittings, compression fittings, and couplings and valves.

Pipes are used to transport something, and tubes to construct something; hence, tubes are defined by the outside diameter and wall thickness (for construction stability), and pipes are measured by inside diameter to allow a calculation for transportation viz., speed, volumes, etc.

About 321 Stainless Steel Tubes

321 is the stabilized version of Stainless Steel 304. The 18/8 blend of chromium and nickel is tempered with titanium to give type 321 protection from intergranular corrosion that can occur after heat treatment. It is protected from temperatures ranging from 800 to 1500° F. The metal displays high strength and resistance to various forms of corrosions, including that from aqueous environments. Type 321 finds application in heavy welding components, along with dynamic environments that are subject to changes.

However, the addition of titanium limits the application of 321 in terms of working. The metal is not recommended for certain welding techniques as it is not consumable. Beyond this, stainless steel 321 has excellent forming characteristics, does not require annealing after being welded, and displays toughness in a range of temperatures. The metal shows strength even when exposed to cryogenic temperatures. Additionally, it is often chosen over Type 304 for its increased resistance to creep and rupture. Both metals may be susceptible to stress corrosion cracking.
