Metinox Overseas is a prominent manufacturer of high performance marine grade piping in Stainless steel 316/316L EFW Pipe that is used in extreme environment. Our Stainless Steel 316 EFW Pipe has molybdenum as well and it goes a long way towards resisting pitting and crevice corrosion in a higher chloride milieu. In case of high-welding applications, we offer the 316L EFW Pipe, which is low-carbon and therefore offers the ability to hold its structure after welding. The pipes are produced according to the ASTM A358 standard which is suitable in cases of high-diameter applications in offshore oil rigs, coastal infrastructure and chemical plant. The 316/316L chemical composition provides better resistance over the 304 EFW series particularly in the face of sulfuric and acetic acids. These pipes are very high tensile strength (515 MPa to 316, 485 MPa to 316L) even at high temperatures in a mechanical manner. Metinox Overseas provides them in different classes and personalized lengths with a specific edge preparation of field welding. As the Middle East grows in its steel use on desalination and the USA on marine engineering, we still hold a huge inventory to serve the projects around the globe.

Stainless steel Grade 316 specifications
It is a medium content of molybdenum austenitic nickel and chromium stainless steel. The availability of molybdenum enhances the pitting chloride resistance. In same it has increased strength under high temperatures. It is a little bit stronger in the presence of high temperatures. It is more resistant to chemical containing environments like tartaric acids, hydrochloric, formic acid sulfuric, acetic etc.
Stainless Steel Grade 316L specifications
The austenitic nickel and chromium steel has the down carbon (high corrosion resistance) 316 grade which is called 316L. Therefore, it is more resistant to intergranular attacks.
All our products are processed in the testing section which guarantees quality of products. In this case various tests are carried out like impact tests and material tests. Report and certificates are also offered by us as well as pipes to confirm the quality of our products. To ensure the quality of SS 316/316L EFW Pipes at the time of delivery we deliver it as big bundles.
