316 stainless steel is created by adding molybdenum and nickel to 304 stainless steel, and belongs to the austenitic stainless steel series. 316 steel has a high temperature resistance of 1200-1300 degrees due to the addition of M0 element. Due to its excellent performance, 316 stainless steel pipes are widely used in medical device manufacturing, pharmaceutical and food industries, chemical industries and other fields.

Duplex steels S32760 and F55 are resistant to various inorganic and organic acids. The added copper element makes them resistant to non-oxidizing acid corrosion. S32760 is also resistant to strong alkali corrosion. However, duplex steels S32760, F55, and 1.4501 are not suitable for use at long-term working temperatures above 300°C, because above this temperature, the toughness of the material will drop significantly.

904L is a low carbon austenitic stainless steel designed for use in severe corrosive conditions. Compared to 316L, 904L stainless steel has more chromium, nickel, molybdenum, and copper. Therefore, 904L steel is more wear-resistant and heavier, but there is not much difference in hardness. 904L stainless steel is also called "rolex 904l​", which means that Rolex uses 904L to make watch cases.

254SMO is an austenitic stainless steel. Due to its high molybdenum content, it has extremely high resistance to pitting and crevice corrosion. This grade of stainless steel was created for containing halides environments such as seawater.

 

Hastelloy C276 is as nickel the main component, and molybdenum, chromium, and a small amount of iron, tungsten, etc. It exhibits excellent comprehensive performance in strong corrosive environments, so it is called the "king of corrosion-resistant alloys". Hastelloy C276 is known for its excellent mechanical properties, including high strength, toughness and ductility. In addition, the alloy can withstand high temperatures and high pressures, making it suitable for environments in the oil and gas, chemical and petrochemical industries.
