With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
robsrolexchronicle.blogspot.com904L is an austenitic stainless steel. In comparison to 316L, its molybdenum addition gives it superior resistance to localized attack (pitting and crevice corrosion) by chlorides and greater resistance reducing acids and in particular its copper addition gives it useful corrosion resistance to all concentrations of sulphuric acid.
904L is a low carbon, high alloy austenitic stainless steel. It has excellent formability, weldability and toughness. It has good resistance to reducing acids as well as chloride attack.
Alloy 904L (UNS N08904) is a superaustenitic stainless steel designed for corrosion and pitting resistance in a wide range of process environments. It is used extensively in the chemical process industry including the production of phosphate-based fertilizers.
Rolex calls 904L stainless steel a corrosion-resistant superalloy. 904L differs from 316L because of extra Chromium, Molybdenum, Nickel, and Copper which gives it improved resistance to acids. 316L is considered a tougher, harder, marine grade steel, but it does not have luster and acid resistance of 904L.

Stainless Steel Alloy 904L. Type 904L is a high alloy austenitic stainless steel that is known for its corrosion properties. This low carbon version of Type 904 stainless steel also offers other benefits to users including: Non-magnetic. Stronger corrosion properties than Type 316L an 317L. Good resistance to sulphuric, phosphoric and acetic acids.
Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. This high alloy stainless steel has added copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion.

904L can be supplied as steel plate/ sheet, round steel bar, steel tube/pipe, steel stripe, steel billet, steel ingot, steel wire rods. electroslag, forged ring/ block,etc. Join Supplier: [email protected]
But those who really know watches realize that there are different types of stainless steel, and some versions are truly remarkable. 904L steel is a combination of nickel, molybdenum, and chromium, and its not meant to be handled with kid gloves.
Sandvik 2RK65, also known as 2RK65, is a high-alloy austenitic stainless steel of '904L' type. The grade is intended for use under severe corrosion conditions within the process industry. Sandvik 2RK65 is available in a range of product forms, such as tube and pipe, billets, blooms and ingots.
To prevent premature deterioration, Rolex moved to 904L, a stainless steel with slightly higher nickel and chromium content. 904L is also resistant to chloride, a potential cause for pitting and corrosion. All Rolex stainless steel, platinum, and gold are made in the Rolex factory.
We specialize in the high corrosion Stainless steel AISI 904L/W.NR 1.4539/ Uranus B6/UNS N08904. For highly critical corrosion problems in the Chemical and Petrochemical industry, this austenitic steel with its high molybdenum and a reduced carbon content grants excellent resistance to: Reductive acids like phosphoric and sulphuric acid
904L stainless steel, is a highly resistant superalloy with excellent anti-corrosion properties. For this reason it not only used by Rolex but also widely applied to components of sea equipment, and salt making equipment.
ATI 904L alloy (UNS N08904) is an austenitic stainless steel designed for a middle to high level of corrosion resistance.
This high alloy stainless steel is added with copper to improve its resistance to strong reducing acids, such as sulphuric acid. The steel is also resistant to stress corrosion cracking and crevice corrosion. Grade 904L 1.4539 UNS N08904 X1NiCrMoCu25-20-5 904S13 is non-magnetic, and offers excellent formability, toughness and weld ability.

Austenitic stainless steel grade 904L is designed to achieve moderate to high corrosion resistance. This is due to the high amount of molybdenum, chromium and nickel content. The resistance properties of grade 904L stainless steel pipes include good resistance to stress corrosion cracking, and pitting and crevice corrosion, as well as inter granular corrosion.
904L Stainless Steel. 904L stainless steel combines molybdenum and copper with iron for tremendously increased resistance to reducing acids like sulphuric acid. It stands up extremely well to chlorides in the environment for low pitting and crevice corrosion, as well as stress corrosion cracking.
The alloy 904L Stainless Steel Sheet shall conform to the required chemical composition such as carbon, manganese, phosphorus, sulfur, silicon, nickel, chromium, molybdenum, copper, nitrogen, and iron. The alloys shall also conform to the required mechanical properties such as tensile strength, yield strength, elongation, and Rockwell hardness.
The 316L Stainless steel is far less scratch resistant than the 904L because it has a much higher Rockwell hardness. The 316L has less nickel in it and is far brighter in appearance and tends to stay that way. Nickel can be an irritant to some. The 904L is often used for body jewelry or piercings and it is not particularly expensive. John Hone
Ground 904L stainless steel bar can be produced, providing a high quality precision ground stainless bar to your tight tolerances. Also available in plate which can be supplied as 904L plasma cut pieces.
The steel grade 1.4539 (also called UNS N08904, 904L and SS2562)is a high alloyed austenitic stainless steel with very good corrosion resistance. The steel is developed to resist corrosion in dilute sulphuric acid and it is suitable to use in details placed in severe corrosion environments e.g. sulphuric acid tanks.
904L Stainless Steel Pipe is a non-stabilised low carbon high alloy austenitic stainless steel. The addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid.
Alloy 904L is a superaustenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of process environments. With its highly alloyed chemistry 25% nickel and 4.5% molybdenum, 904L provides good chloride stress corrosion cracking resistance, pitting and general corrosion resistance superior to 316L and 317L molybdenum enhanced stainless steels.
904l stainless steel vs 316l. 904L has greater amounts of chromium and nickel than the 316L grade.It is typically used in the chemical industry for severe corrosion Environments i.e better resistance to pitting, SCC, IGC etc. 316L Stainless steel is far less scratch resistant than the 904L because it has a much higher Rockwell hardness.
In all kinds of phosphoric acid,904L stainless steel pipe s are superior to normal stainless steel tubes. In the highly oxidized nitric acid, the corrosion resistance is low compared to the high alloy steel, which is non-molybdenum. In hydrochloric acid, the use of 904L stainless steel pipe is limited to a low concentration of 1-2%.
