Stainless steel is a low carbon steel and chromium content but offers high corrosion resistance. Stainless steel, because of its stability, strength and anti-corrosive and high heat properties, is one of the most popular materials used for fasteners. A flexible, economical alloy benefits from the combination of steel strength with its superior anti-corrosion and heat-resistance properties.
You will find the following types while looking for robust and effective grades of stainless steel fasteners in the market.
The Stainless Steel 18-8 grade is also referred to as 304 SS for their chemical composition is same in both 18-8 & 304 Stainless Steel. As the name suggests, the grade 18-8 consists of 18% chromium, and 8% nickel which makes it an excellent resistance to corrosion. When it comes to 304 grade, it is splitted into two grades, which are 304L and 304H depending upon their carbon content. Again as the name denotes, 304H is high carbon grade and 304L is a low carbon grade. The Stainless Steel 304 or 18-8 stainless steel has high corrosion resistance, is stronger than mild steels and has less heat sensitivity than 302 grade.
The composition of the alloy is one of the reasons that the Type 316 Stainless Steel Fasteners have stronger mechanical and physical properties. Stainless Steel Fasteners Grade 316 are intended for applications under harsh environmental conditions. These industries therefore need better protection and an improved resistance to corrosion provided by the stainless steel series of 300 grades.
Grade 304 (18-8)
Grade 304 possesses an excellent combination of corrosion resistance, strength and fabricability. Stainless Steel Fasteners of this grade are being extensively used in almost every industry today.
Grade 304 is suitable for use in sinks, table tops, urns, stoves and various appliances because of its tolerance to food, inorganic chemicals and most organic chemicals. In the brewing and food processing industries, fasteners of this type are also used.
