Stainless Steel 310H pipes contain a high concentration of chemical components such as Chromium (24-26%) and Nickel (19-22%). Other constituent elements in this standard are manganese, silicon, sulfur, phosphorous that gives the pipe its distinctive characteristics. Chromium being an essential element in the mix increases the products’ longevity as it prevents the steel from oxidizing at high temperatures thus, minimizing the risks of corrosion. The addition of nickel increases it’s hardenability while also preserving the ductility of the steel allowing the structures to bend and deform to some extent without rupturing it. Therefore, SS 310 EFW pipes can be an ideal choice for high-temperature applications.

Carbon is the most important alloying element in steel, and it increases hardness, tensile strength, and heat treatment reaction when more of it is added (hardenability). However, weldability is also threatened if carbon levels continue to rise. Stainless Steel 310H pipes contain up to 0.10 percent carbon. (Can be present up to 2%, although most welded steels have less than 0.5%), which is indicated by the letter “H” in the name, and such pipes are known for their impressively enhanced formability.

EFW in SS 310H pipes stand for ‘Electric Fusion Welding’. It refers to the method used to manufacture the pipes. Welded pipes are formed in the EFW manufacturing process by hot or cold rolling plate and welding the seam. Such EFW pipes are developed in accordance with international quality standards in order to achieve the highest quality level.
Stainless Steel 310H EFW Pipes are appropriate for flanging, bending, and parallel forming processes, and also for fusion welding. The Pipes manufactured from Grade 310H have excellent toughness, even down to cryogenic temperatures, although other grades are normally used in this environment. All of these features add to the value of SS 310H EFW pipes.
