Competitive Advantage:

Super corrosion resistance: strong resistance to a variety of strong corrosive media, especially in sulfuric acid, phosphoric acid, acetic acid and other non-oxidizing acids and chloride-containing environments, corrosion resistance is far superior to conventional stainless steel, such as 304, 316, and can even withstand high concentrations, high temperatures in the corrosive media, is one of the few materials that can be operated stably for long periods of time in strong acidic conditions.

Excellent mechanical properties and toughness: tensile strength of about 550MPa, yield strength of 220MPa or more, both good strength and plasticity, can withstand a certain load; at the same time has excellent toughness, even at low temperatures is not easy to brittle fracture, can adapt to extreme temperature fluctuations in working conditions.

Good processing and welding performance: excellent plasticity, stamping, bending, rolling and other hot and cold processing, can be made into plates, tubes, flanges and other forms; weld heat-affected zone is not easy to produce embrittlement phase, weld corrosion resistance is close to the base material, no complex heat treatment after welding to maintain stable performance.

Outstanding oxidation resistance and fatigue resistance: it can form stable oxide film under medium and high temperature environment to resist oxidation corrosion; it is not easy to be fatigued under alternating load, which is suitable for equipment parts in dynamic working condition for a long time.

Applications:

With strong corrosion resistance and excellent comprehensive performance, 904 stainless steel occupies an irreplaceable position in strong corrosive extreme working conditions. In chemical industry, it is the core material of sulfuric acid recovery device and phosphoric acid production equipment, which can resist the erosion of acid medium in high concentration and high temperature, and is used to make reaction kettle, heat exchanger and conveying pipeline to ensure the continuous stability of chemical production; in pharmaceutical industry, it is suitable for dealing with the synthesis equipment of the drugs containing strong corrosive components, such as organic acid reaction tank, purification device, etc., whose corrosion resistance can meet the stringent requirements of the drug production on the purity and safety. Its corrosion resistance can meet the strict requirements for purity and safety of drug production. In metallurgical industry, it is commonly used in electrolysis tanks, pickling tanks and other equipments, which can resist the corrosion of electrolysis and pickling solution and prolong the service life of the equipments.
