How does the performance and use of stainless steel materials change after adding molybdenum?

The performance of stainless steel with molybdenum is better than that of other grades. It has enhanced resistance to chloride ions and contaminants, and has better pitting and crevice corrosion resistance to prevent salt and corrosion. Corrosion caused by contaminants is very useful. This kind of molybdenum-containing stainless steel mainly has several grades including 316 molybdenum stainless steel, 316L molybdenum containing molybdenum stainless steel and 317 stainless steel.

316 molybdenum containing stainless steel

316 molybdenum-containing stainless steel has a molybdenum content of 2% to 3%. It has good corrosion resistance, work hardenability and high temperature strength. It can be used under harsh conditions and is the most widely used molybdenum-containing stainless steel.

In the chemical industry, it has good corrosion resistance and manufactures chemical, dye, paper, oxalic acid, fertilizer and other production equipment. It is suitable for use in the food industry and is almost a standard material in the food and beverage industry and can be used as a tank, pipe and heat exchanger material for food processing and processing.

In various types of aqueous media, such as distilled water, drinking water, river water, boiler water, seawater, etc., the corrosion resistance of 316 molybdenum-containing stainless steel is excellent. Moreover, it has good resistance to chloride in the air and is resistant to marine erosion. It is commonly used in marine environments, such as materials used in marine and coastal construction, and equipment used in seawater.

316 molybdenum-containing stainless steel is also used in the medical field and is intended for use as a tank, pipe and heat exchanger material for pharmaceutical production. In addition, it is used in film processing equipment, lighting, ropes, CD rods, bolts, nuts.

316L molybdenum-containing stainless steel

The molybdenum content of 316L molybdenum-containing stainless steel is generally 3% to 4%, the maximum carbon content is 0.03%, and L represents low carbon. As a low carbon series of 316 stainless steel, it has the same performance as 316 stainless steel, and it has excellent resistance to intergranular corrosion. It is especially suitable for products with special requirements for grain boundary corrosion. It has good properties against chloride stress corrosion cracking and can be used in areas where it cannot be annealed after welding and requires maximum corrosion resistance. For example: used in the marine sector, oil and gas industry, chemical processing industry, petrochemical industry, etc.

317 molybdenum containing stainless steel

The molybdenum content of 317 molybdenum-containing stainless steel is 6% to 7.3%. It is the most corrosion-resistant stainless steel. It has excellent corrosion resistance and durability in harsh and corrosive environments. It is used in chemical petrochemical, oil and gas. Mining, power industry and other applications, such as power plant condensers, subsea pipelines, industrial water pipelines, key components of nuclear power plants.

317 molybdenum-containing stainless steel has excellent corrosion resistance and can be used in coastal environments, industrially polluted environments, and other corrosive environments. The service life of the manufactured components is significantly improved, the number of maintenance is reduced, thereby saving the life cycle cost, and also Can be recycled and reused.

317 Molybdenum-containing stainless steel is also a plastic material with good reworkability, easy to form, process and weld, and it has good ductility, is particularly easy to install and modify, and is commonly used in buildings and structures, such as: building facades, Various streetscapes such as roofing, curtain walls, canopies, railings, pool linings and ancillary equipment, sun visors and sculptures.

Molybdenum-containing stainless steels have such excellent corrosion resistance, are environmentally friendly, and can reduce the cost of use, making them an ideal material choice. Moreover, it is highly competitive and has been favored by many people. You can determine the more suitable molybdenum-containing stainless steel material according to the specific use.
