What Makes 904L Steel So Unique?

Its low carbon content minimizes intergranular corrosion and makes it resistant to welding-induced sensitization. It can be used in heat exchangers, bleaching systems, pipeline systems, and devices for controlling pollution.

A specification called ASTM B649 covers low-carbon alloys like grade 904L. High temperatures are ideally suited for the performance of this highly alloyed, super austenitic stainless steel. Ferrule fittings made to Stainless Steel 904l Tube Fittings are offered in two different states: cold drawn and solution treated. Typically, a chemical or product analysis is used to check the chemistry of the fittings covered by this specification. Additionally, a tension test is used to assess the parameters related to the tensile requirements of the stainless steel UNS N08904 double ferrule tube fittings, such as elongation, tensile, and yield strength.

Heat treatment is not necessary for forged quality material, such as the 904L Tube Fittings. Hydraulic Stainless Steel 904L Tube Fittings are manufactured in accordance with precise guidelines, including the pressure rating, construction style, and dimensions. The ASME SB 649 SS 904L Hydraulic Fittings have strict criteria since they are intended for use in industries with high-pressure situations. The use of 904L Instrumentation Fittings, on the other hand, is for both low and high-pressure applications, conveying, measuring, and handling system flow, pressure, and temperature while providing for system calibration.

Compression fittings made of stainless steel 904L are common in plumbing and electrical conduit because they are more dependable than threaded ones.

Is 316L preferable to 904L?

Type 904L is more corrosion-resistant than 316L because it contains more chromium, molybdenum, and nickel. It also contains some copper, manganese, and silicon. But the biggest drawback of 904L is that it is still more difficult to produce than 316L, in addition to its exorbitant price.

What Components Make Up 904L Steel?

Super austenitic stainless steel Alloy 904L (UNS N08904) is intended for moderate to high corrosion resistance in a variety of process conditions. High levels of nickel and chromium, as well as the additions of molybdenum and copper, guarantee good to outstanding corrosion resistance.

Is Stainless Steel 904L Magnetic?

Because of its increased nickel and molybdenum alloying, alloy 904L outperforms other austenitic stainless steels. In all situations, the grade is nonmagnetic and has outstanding formability and weldability. This grade's austenitic structure also provides outstanding toughness, even at cryogenic temperatures.
