Stainless Steel 316 Nipple

It is common to fabricate SS 316L Hexagon Nipple into many different shapes. Stainless Steel 316 One End Threaded Nipple has excellent malleability means they perform well in deep drawing, spinning, stretching, and bending. Stainless Steel 316L Both End Threaded Nipple has a lower grade of wear-resistant steel plate, which is an as-rolled product made to chemistry to achieve a desired Brinell range.

Stainless Steel 316 Concentric Swaged Nipple is used in applications of slight abrasion where abrasion resistance combined with economy is the primary concern. SS 316L Eccentric Swaged Nipple is a versatile general-purpose stainless steel product with good resistance to atmospheric corrosion, many organic and inorganic chemicals, and food and beverages. Stainless Steel 316 Nipple is used when end product requires a lot of welding, which is further widely used in chemical processing plants. The combination of chromium, nickel, molybdenum, and copper make Stainless Steel 316L Nipple resistant in a range of sulphuric acid environments. Process environments that do not corrode Alloy 316 Nipple will not attack this grade.
