What is Stainless Steel 304/304H/304L Fasteners ?

304 /304L/304H Stainless Steel Fasteners are known for their excellent resistance against corrosion and their properties that make them extra withstand different temperatures and last for a long time. These fasteners are one of the most widely used ones compared to the other stainless steel fasteners.

304 /304L/304H Stainless Steel Fasteners have a lower carbon content and can therefore reduce the carbide precipitation that can occur. Hence, these are used in a wide range of utilities where the temperature could be elevated. These fasteners can be available in different shapes, sizes, thicknesses, and dimensions depending on the specifications. And thus are used in a wide range of industries such as chemical industries, gas industries, oil industries, etc.

Sumit Impex is known for producing high-quality 304 /304L/304H Stainless Steel Fasteners. These fasteners have chromium in a higher amount and carbon in a lower amount. The chemical composition of these fasteners comprises 18 percent of chromium and 8 percent of nickel. There is about 0.07 percent of carbon content in the chemical composition of these fasteners.

Sumit Impex provides highly durable fasteners, these possess incredible tensile strength, and is excellently resistant to corrosion. It is basically a non-magnetic alloy that could be made into a magnetic one once undergone cold working. These fasteners are widely used in applications where the temperature and pressure are both high and in a not-so-favorable condition.
