Description

Metline is a specialized manufacturer and supplier of stainless steel 316 hex nuts, along with SS 316 bolts or studs and washers. SS 316 hex nuts are generally manufactured in accordance with DIN Standard 934 or ISO Standard 4032. We can offer fastest delivery for SS 316 hex nuts and SS 316 heavy hex nuts manufactured as per DIN 934, DIN 6923, DIN 1587, DIN 928, DIN 929.

Stainless steel 316 (SS316) is an austenitic chromium-nickel stainless steel containing deliberate amount of molybdenum which increases general corrosion resistance and especially improves its pitting resistance to chloride ion solutions. The molybdenum addition also provides increased strength at elevated temperatures. Thus, SS316 is also known as “Mo-Added” version of SS304. Stainless steel 316L (SS316L) is the extra-low carbon version of SS316 that minimizes harmful carbide precipitation during welding. Both SS316 and SS316L have exceptional resistance to corrosion against sulfuric, hydrochloric, acetic, formic, and tartaric acids; as well as against acid sulfates and alkaline chlorides. They are widely used in exhaust manifolds, heat exchangers, pharmaceutical equipment, cryogenic piping, valve and pump trims, chemical & petrochemical process, pulp and paper industry, and food industry, etc.

Meaning

A nut is a type of fastener with a threaded hole. Nuts are almost always used opposite a mating bolt to fasten a stack of parts together. The two partners are kept together by a combination of their threads' friction, a slight stretch of the bolt, and compression of the parts.
