316 PIPES TUBES

Brief guide on stainless steel 316 pipes

Stainless steel has become very important and one of the most popular and used metals around the world. It does not corrode, rust or stain as easily as ordinary steel. This is the reason why so many of our tools and equipment nowadays are made up of stainless steel 316 pipes. Its resistance to corrosion and staining makes it ideal for many applications. Many of its beneficial properties are particularly suitable for strength and energy industry, from traditional coal-fired power plants to the latest forms of renewable energy.  Among these properties, the incredible corrosion resistance of stainless steel is a must, several extreme conditions for power plants must be established, such as coastal or underwater areas.

Stainless Steel 316 Pipes

  • Type 316 (UNS 31600) is an austenitic chromium-nickel stainless steel alloy containing molybdenum. This additive increases corrosion resistance, improves the resistance to pitting of chloride ion solutions, and provides better resistance to elevated temperatures.
  • The properties of this austenitic stainless steel are similar to those of Type 304, except that Type 316 is slightly more temperature resistant. When it comes to formability, 304 stainless steel is often the best choice for forming operations due to its higher molybdenum content for alloy 316; this means that it has higher strength and a faster solidification rate, which can adversely affect the shape.
  • While 316 can typically be drawn and formed similarly to 304, temperature variations can make those processes challenging. For instance, the 316 alloys may become magnetic when cold worked. Increased resistance to corrosion, especially to sulfuric, hydrochloric, acetic, formic, and tartaric acids, as well as to corrosion caused by sulfate acids and alkali metal chlorides.
  • The low carbon version of 316 stainless steel pipes has a higher resistance to intergranular corrosion.
