Stainless Steel 316 fasteners are known as Marine grade alloy. Ranked second to SS 304 Fasteners, in terms of popularity, these SS 316 Fasteners have much better properties with regards to their corrosion resistance as well as mechanical properties. The marine industry is particularly partial towards using 316 Stainless Steel Bolts across engineering applications because they have excellent resistance to seawater and brine solutions. Galvanizing it or coating fasteners with ceramic improves their resistance to seawater. Protecting the stud bolts both below and above water is possible by the application of a ceramic coating to Bolts. A ceramic coat over SS316 Bolt discourages the growth of sea organisms and algae on the Bottom while preventing oxidation of treated surfaces. SS 316 hex bolts are also used on boats or for shipbuilding because the alloy is resistant to chorine induced stress-related corrosion cracking. The chromium on the surface of these bolts reacts with the air to form a passivated oxide layer - which does not promote corrosion.
The resistance to pitting, crevice corrosion, and general corrosion of this molybdenum-bearing SS 316 Bolts and Nuts are much higher than in grade 304. In particular, this is a property that is ideal for chloride environments. These A4 Fasteners also exhibit high mechanical properties like a higher creep, stress to rupture, along with high tensile strength at elevated temperatures. Hence, frequently 316 Stainless Steel Fasteners find use in process streams containing chlorides or halogen compounds. Another characteristically cardinal feature of the alloy is its austenitic microstructure. The austenitic microstructure of the nuts exhibits excellent toughness. The toughness is a property even down to applications with cryogenic temperature settings. A specification that covers high-temperature stainless steel components, including fasteners - is ASTM A193. During the manufacture of these AISI 316 Bolts, Stud Bolts, Hex Bolt, Threaded Rod, Screws, Washers, Nut Bolts, etc. under specification ASTM A193, the exact composition is to be used, without the inclusion or exclusion of elements. It signifies that the chemistry needs to be as the specified grade.
UNS S31600 Bolt is also what many buyers refer to as a sanitary stainless steel alloy. Industrial fasteners such as SS 316 Threaded Rods are a part of industries like pharma as well as the food and beverage industry. These sectors require equipment that is not only non-toxic but also can get cleaned easily without the deposition of the raw material of the product or the cleaning reagents used on them. Since this alloy is resistant to several acids, neutral solution or alkaline compounds, the ASTM A193 316 Bolt is used to construct equipment, the chances of these compounds getting attached to smooth finished nuts and bolts are less. Therefore, any occurrence of corrosion is eliminated effectively, particularly in the food and beverage industry. Usually, 316 Stainless Steel Nut Bolt used across several industries, including pulp & paper, textiles, sugar, rubber, etc. prefer using coated ones. The coating used on the surface of these grade 316 threaded rods improves wear resistance while reducing corrosion resistance to some extent. Commonly materials like zinc, phosphate plating, galvanization, Teflon could be used to coat nuts, bolts, washers, etc. The application of a coating could serve as a pre-treatment for painting screws, threaded rods, or hex bolts.
