Difference between 304 and 316 stainless steel

1. Different advantages:

304 stainless steel has good processing performance and high toughness.

316 stainless steel has good corrosion resistance, atmospheric corrosion resistance and high temperature strength.

2. Different application areas:

304 stainless steel is widely used in industrial and home decoration industries and food and medical industries.

316 stainless steel is used in seawater with equipment, chemical, dye, paper, oxalic acid, fertilizer and other production equipment, photography, food industry, coastal facilities, ropes, CD rods, bolts, and nuts.

3. The density is different:

The density of 304 stainless steel is 7.93 g/cm³.

The density of 316 stainless steel is 8.03 g/cm3.

Extended information:

304 stainless steel is widely used in curtain walls, side walls, roofs and other construction purposes. However, 316 stainless steel is best used in severely corrosive industries or marine atmospheres.

With stainless steel sliding doors, people have fully realized the advantages of using stainless steel in structural applications. There are several design criteria that include 304 and 316 stainless steel. Because the “duplex” stainless steel 2205 has integrated good atmospheric corrosion resistance with high tensile strength and elastic limit strength, this type of steel is also included in the European standards.

Product shape In fact, stainless steel is manufactured in full-standard metal shapes and sizes, and there are many special shapes. The most commonly used products are made of thin plates and strip steel, and medium and heavy plates are also used to produce special products, such as the production of hot-rolled structural steel and extruded structural steel.

There are also round, oval, square, rectangular and hexagonal welded pipes or seamless steel pipes and other forms of products, including profiles, bars, wires and castings.
