Product Details

Advantages of the 904L stainless steel flanges:

JINLUN had the excellent forging equipments, experienced workers handle forging stainless steel 904L, the suitiable furnace heating the stainless steel 904L.


It is very difficult for most of other producers to forge 904L stainless steel flange well, the 904L material is easy to be crack when forging. With long experiences and advance technology, we forged a lot of 904L stainless steels successfully, in general, we need to press the 904L forging flanges 4-5 times, it's means that the raw forging should be back to the furnace for heating 4-5 times, for the normal stainless steels, it's only need to press 2 times at most.


Product apprecation domain:

This 904L stainless steel flange widely used for kinds of petroleum and petrochemical equipments, storage and transport equipments for vitriol oils, power plant flue gas desulfurization device, organic acid treatment system, seawater treatment equipments, seawater heat exchanger, paper industry equipments, sulfuric acid equipments, nitric acid equipments, acid and pharmaceuticals industry and other chemical equipments, pressure vessels, food equipments, centrifugal machines, reactors, etc.


Quality grauantee:

Checking the chemical elements of raw materials by spectrometer, detection of defects by magnetic powders and ultrasonic. Ultrasonic testing after pre-machined. Measuring the sizes of the raw forgings by kinds of instruments.


Except the standard flanges, we can produce the 904L stainless steel flanges according the customer's drawings or sample.

904L Stainless Steel

904L stainless steel is a low-carbon alloy austenitic grade of SS. It is used extensively for its superior corrosion resistant properties.

Conventional chrome stainless steels are comprised of nickel. However, 904L SS is unique in its the addition of copper. This is what gives this non-magnetic grade excellent toughness, formability and weldability. This non-stabilized high alloy is also resistant to corrosion cracking and crevice corrosion.
