Chemical components such as Chromium (24-26 percent) and Nickel are abundant in Stainless Steel 316 EFW Pipes (19-22 percent). Manganese, silicon, sulfur, and phosphorous are other key elements in this standard that give the pipe its specific features. The use of chromium in the mix extends the product's longevity by preventing the steel from oxidizing at high temperatures, reducing the chance of corrosion. The inclusion of nickel boosts the steel's hardenability while keeping its ductility, allowing it to bend and deform to some extent without rupturing. As a result, SS 310 EFW pipes are a good option for high-temperature applications.
Carbon is the most common alloying element in steel, and adding more of it increases hardness, tensile strength, and heat treatment reaction (hardenability). However, if carbon levels continue to rise, weldability will be jeopardized. Up to 0.10 percent carbon can be found in stainless steel 316 pipes. (Can be present up to 2%, however most welded steels have less than 0.5%), which is represented in the name by the letter "H," and such pipes are known for their substantially enhanced formability.
EFW stands for 'Electric Fusion Welding' in SS 316 pipes. It refers to how the pipes are made. In the EFW manufacturing process, welded pipes are created by hot or cold rolling plates and seam welding. To reach the highest degree of quality, such EFW pipes are developed in compliance with international quality standards.
Flanging, bending, and parallel forming techniques, as well as fusion welding, are all possible with stainless steel 316 EFW pipes. Although other grades are commonly utilized in this environment, pipes made from Grade 316 exhibit remarkable durability, even at cryogenic temperatures. All of these aspects contribute to the SS 316 EFW pipes' worth.
