1.4539 – grade stainless steel with a resistance to acids

Stainless 1.4539 is a type of stainless steel, which is characterized by high resistance to acids and pitting corrosion and stress corrosion. In addition, this species is a super austenitic, which are classified to a certain group of nickel. This type of steel is a nickel-chromium steel with molybdenum, titanium and copper. In addition, it is the steel super austenitic. It is the addition of molybdenum increases the resistance of steel corrosion. The most common form of delivery of this species are long and flat products used in the energy industry, petrochemical and chemical industries. The species has a high resistance to sulphuric acid at high temperatures, is resistant to nitric acid, phosphoric and phosphorous.

N08904 high-alloy stainless steel with copper and titanium

Steel N08904 has a high content of nickel and chromium, so it keeps corrosion resistance even when working in very aggressive environments. In addition, molybdenum beneficial effect on the properties of steel. Copper makes steel N08904 is resistant to reducing gases and makes that improves its ductility and resistance to acids.

AISI 904l -mechanical properties of the steel grade

AISI 904L is resistant to intergranular corrosion in the delivery state and who are allergic and pitting corrosion and stress corrosion. In addition, it has corrosion resistance pin, crevice corrosion, pitting. Shows when you work very good weldability, so is extremely easy in the material heat treatment and plastic. The process of solution treating is carried out at temperatures from 1050-1150 ° C, while the process of forging and rolling must have a temperature of 900 to 1200 ° C.

Stainless steel 1.4539 is in terms very similar to 1.4547 or 1.4529, although its corrosion resistance is most commonly compared to steel with a series of duplex structures ferritic-austenitic. The most important advantage of this structure is steel austenite, which substitute material. Above all, this grade of stainless steel is a very convenient material for work in an environment of acids: acetic acid, oxalic, citric, lactic, formic.

How to use steel AISI 904L in the industry?

Grade of stainless AISI 904L is primarily used for the production of installations and equipment. Steel is used for the production of equipment for water desalination, construction machinery needed in the food industry, pharmaceutical and cryogenic. It created are scrubbers in coal gas purification filters, capacitors, or heat exchangers. In addition, this irreplaceable material for shipbuilding, marine and chemical and steel. The pulp is used to manufacture devices to whiten paper.
