ASTM A193 Machine Bolts & SS 304 Fasteners manufacturer in India

Across the world, Stainless Steel 304 Fasteners is referred by its trade names that include grade 18-8, or UNS S30400. A versatile alloy, these 304 Stainless Steel Fasteners are very popular in many industries. The expression 18-8 is a footnote to the chemistry of SS 304 bolt. The content of chromium in the 18-8 alloy is about - 18% with around nickel is 8%. Higher content of chromium in these UNS S30400 bolt implies that this stainless steel grade has high resistance properties, particularly to oxidation. Chromium aids the formation of a self-healing passivate oxide layer on the surface of the Stainless Steel 304 Bolts and Nuts, which is why the alloy is not susceptible to getting wear. SS 304 Fasteners has a high resistance to oxidation when used intermittently in applications where the temperatures reach 870 °C. On the other hand, the appliance of the threaded Rod leads up to a temperature of 925 °C in continuous service.

Nickel, when added in a considerable aggregate or this instance close to 8% of its total weight, improves the corrosion resistance properties. In austenitic stainless steel alloys such as SS 304 bolts and nuts, nickel tends to form austenite. The formation of austenite in the metal of A2 Fasteners is what not only imparts superior toughness or impact strength but also improves the tensile strength of these ss 304 nut bolt at both high as well as low temperatures. Cold working the alloy also conveys good tensile strength and hardness to these fasteners, although it becomes slightly magnetic.

The 304 ss bolts are thoroughly pliable & the execution of any forming steps are reasonable. Production of ss 304 fasteners such as UNS S30400 Nuts, Washer, Stud Bolts, Bolts, screws, Hex Bolt, Threaded Rod, and Nut Bolts could use standards or specifications set by regulatory bodies like the ASTM. One such specification that covers 304 stainless steel bolt for high-temperature use is the ASTM A193. Under this specification, the ASTM A193 304 stud bolts are to conform to the chemistry. Hence, the inclusion of an unspecified content to their metal is restricted.

304 Stainless Steel Fasteners not only exhibits high resistance to atmospheric corrosion but also to the different chemical and alkali compounds seen in the foods and beverage industry. SS 304 Bolts and Nuts are also resilient to many organic and inorganic chemicals present in both moderately oxidizing and reducing environments. The high content of chromium in the alloy is what provides resistance to the SS 304 Nut Bolt from oxidizing solutions such as nitric acid up to 55% weight even to a temperature of about 176°F. However, in applications that contain highly reducing environments such as those chlorides and sulfuric acid, these fasteners exhibit poor performance. Although SS 304 Nuts and bolts do not have exceptional corrosion resistance properties, their preference is for several reasons. Firstly, grade 304 screws are inexpensive as compared to other stainless steels. Second, they are an improvement over carbon steels. S30400 bolts are available easily in comparison to many alloy grades. In instances of modification in its carbon content, alloy 304 could be dual certified as 304L or 304H, depending on its lowered or increased carbon content.
