Description

Metline is a specialized manufacturer and supplier of stainless steel 304 hex nuts, along with SS 304 bolts or studs and washers. SS 304 hex nuts are generally manufactured in accordance with DIN Standard 934 or ISO Standard 4032. We can offer fastest delivery for SS 304 hex nuts and SS 304 heavy hex nuts manufactured as per DIN 934, DIN 6923, DIN 1587, DIN 928, DIN 929.

Stainless steel 304(SS304) is the most basic stainless steel known as 18-8 grade with higher chromium and low carbon content. The low carbon content restricts carbide precipitation during welding as well as minimizes its susceptibility to intergranular corrosion. Stainless steel 304L(SS304L) is an extra low-carbon variation of SS304 with a 0.03% maximum carbon content that eliminates carbide precipitation due to welding. Both SS304 and SS304L have excellent resistance to a wide range of atmospheric, chemical and petrochemical, and food industry corrosions. Usually, they can be used in applications with the maximum temperature of 1650°F[900°C] exhibiting good oxidation resistance.

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.
