SEAMLESS STAINLESS STEEL PIPE NIPPLE 304/316 1/2" BSPT/DIN/NPT ASTM A312
STAINLESS STEEL PIPE NIPPLE
Selecting your material grade for your pipe nipples
Seamless tube is made from solid round billets of stainless steel. Billets are semi-finished products used to produce stainless steel tubes, bars and rods. The billet is pulled or pushed over a mandrel that extrudes the billet into a hollow tube shape
304 stainless steel has a high resistance to rust. It withstands corrosion from most oxidizing acids and is often used for kitchen and food applications. However, it is susceptible to corrosion from chloride solutions (notably saline environments with high amounts of sodium chloride). Chloride ions can create localized areas of corrosion, or what is also known as "pitting," which can spread beneath protective chromium barriers to compromise internal structures. Solutions with as little as 25 ppm of sodium chloride can begin to have a corrosive effect.
316 grade is the second-most common form of stainless steel. It has almost the same physical and mechanical properties as 304 stainless steel and contains a similar material make-up. The difference is that 316 stainless steel incorporates about 2 to 3 percent molybdenum, which increases corrosion resistance - particularly against chlorides and other industrial solvents. 316 stainless steel is commonly used in many industrial applications involving processing chemicals, as well as high-saline environments such as marine, coastal regions and outdoor areas where de-icing salts are common. Due to its non-reactive qualities, 316 stainless steel is also used in the manufacture of medical industry, surgical instruments, food industry, & pharmaceutical equipment.
