Detailed Information

Prashaant Steel & Alloys is a major producer and supplier of stainless steel 304L Fasteners. The SS UNS S30403 Fasteners that we produce at Prashaant Steel & Alloys are commonly used in the industry due to their superior consistency and dimensional accuracy. Prashaant Steel & Alloys manufactures and sells ASTM A193 SS 304L Fasteners in different sizes and dimensions per our customers’ requirements. We believe in total customer loyalty, which is why we produce the SS UNS S30403 Fasteners, which are incredibly tough even at cryogenic temperatures. The ASTM A193 SS 304L Fasteners have non-reactive properties, allowing them to be used in a wide variety of applications, including the manufacturing of medical and surgical instruments. For the development of SS UNS S30403 Fasteners at Prashaant Steel & Alloys, we use some of the best raw materials available, resulting in superior SS 304L Fasteners.

Stainless steel of grade 304 fasteners contains nickel of 8% and chromium of 18% and is the most commonly used grade for the production of fasteners. It possesses an excellent combination of strength, corrosion resistance and fabric ability. Fasteners of this grade are being extensively used today in almost every industry.

Stainless Steel 304H Hex Cap Screws has greater short term and long term creep strength than SS 304L at temperatures above 500 Degree C. The higher carbon content of Stainless Steel 304H Hex Screws may lead to sensitization with a concomitant loss of corrosion resistance in a corrosive environment. Stainless Steel UNS S30409 Allen Cap Screws is often used in industrial boilers, pressure vessels, heat exchangers, pipelines and condensers.

Alloy 304L Bolts (Din 1.4307 Bolts) Stainless Steel 304L Socket Cap Screws is a lower carbon variant of SS 304 which can be welded without the resulting issue of carbon precipitation. Stainless Steel 304L Countersunk Slotted Screws often eliminates the necessity of annealing weldments except for applications specifying stress relief. Stainless Steel UNS S30403 Machine Screws is often used in food processing equipment, particularly in beer brewing, milk processing, and wine making.

Applications of SS 304L Fasteners

304L Fasteners in stainless steel are mainly used in applications of heavy stress loads. Food processing equipment, such as milk processing and beer brewing, is made with SS UNS S30403 Fasteners. Heat exchangers are also made for the ASTM A193 SS 304L Fasteners. They’re also used in the manufacture of chemical tanks. Other uses for the SS 304L Fasteners include the design of architectural frameworks and panelling work. The ASTM A193 SS 304 Fasteners are also used to render decorative trims and railings.
