Introduction of Grade A2 & A4 Stainless Steel Fasteners:

A2 grade is also known as stainless steel 304. This grade has some magnificent properties and characteristics which are genuinely different from other grades. A2 grade has some legit properties, which makes it applicable in various industries for a variety of purposes. These A2 and A4 stainless steel fasteners are made from high-quality grades and raw materials, and these fasteners are enriched with ductility and durability.

A4 grade is commonly called 316 stainless steel grade, beneficial for various purposes. This stainless steel grade is made from extra ductile elements, and these elements are generally known for providing high resistance.

Grade A4 (316 Stainless Steel Grades):

There are mainly three basic types of grade 316. Grade 316 is made from high-quality chemical compositions. The grade has high weldability and sturdiness. These stainless steel fasteners are commonly used for various applications in hot or cold temperatures. These fasteners are efficient and effective for industrial and commercial usage. The grade also has smooth stability and solidity. Grade A4 provides excellent protection from procedures like pitting and forging.

Grade A4 Fasteners :

A4 fasteners are among the most highly demanded fasteners in all industries. These fasteners are widely used for joining or connecting two or more objects steadily together. These fasteners are commonly made from high-quality material that holds heavy objects and provides a tight grip on them. These fasteners are one of the most popular amongst all the industries.

A4, which is 316, has another version which is called 316L. 316L is the lower carbon version of A4, which provides excellent protection from heavy gauges. A4 is also indicated as marine grade as it has a high ability to resist corrosion, crevice corrosion, and stress cracking.

Grade A2 Fasteners :

This grade is also one of the most authentic grades that provide extreme protection from various heat treatments, bad weather conditions, and high pressure. These fathers are commonly known for creating non-permanent and long-lasting joints between two objects. This grade is also known as 18/8 grade. 

Chemical composition:

The chemical composition of these grades is almost similar; It includes high amounts of molybdenum and nickel. A4 includes 18% chromium and 8% content, whereas A2 includes 18% chromium and 10% nickel content. The high amount of chromium provides great resistance from various chemical procedures. These grades are known for their great service and protection from corrosion, crevice corrosion, and stress cracking. It also resists erosion, rusting, and reduction.
