Austenitic stainless steels are the most widely used stainless steels, accounting for about 75% of the total stainless steel consumption. The rapid development of the chemical industry and petrochemical industry has put forward higher requirements for the corrosion resistance and strength of stainless steel. For example, the 304/304L dual grades stainless steel means it has […]
With the development of ultra-supercritical units, the high-temperature strength of traditional 18-8 Austenitic stainless steels (such as TP304H steel) has been unable to meet their needs with steam parameters of 600℃. For this reason, Japan Sumitomo Metal Corporation has developed new materials for the boiler heating surface pipeline of the unit, like TP347HFG steel, SUPER304H […]
Ordinary consumers have some misunderstandings about stainless steel, they think that the magnetic stainless steel is not qualified 304 stainless steel. As we know, according to the structure under room temperature，stainless steel can be divided into Austenite such as 201, 304, 321, 316, 310, Martensite or Ferric such as 430, 420, 410. Austenites are non-magnetic […]
The bellows tube heat exchanger is an upgrade based on a straight (bright) tube heat exchanger. The design of the crest and trough of the wave inherits the advantages of the tubular heat exchanger such as durability and safety, and at the same time overcomes the defects such as poor heat transfer capacity and easy […]
Grades 304 and 430 are commonly used stainless steel materials. 304 stainless steel is a general type of chromium-nickel austenitic stainless steel, the density of 7.93 g/cm3, also known as 18/8 stainless steel, is 300 series of stainless steel is the most commonly used steel. It can withstand high temperature 800℃, has good processing performance […]
316LN is the Nitrogen addition version based on 316L steel (0.06% ~ 0.08%), so that it has the same characteristics as 316L, has been used in the manufacture of high-temperature structural components in fast breeder reactor (FBRS). Reducing the carbon content greatly reduces the susceptibility to stress corrosion cracking due to welding in subsequent corrosive […]
