What is ss904l material?
Introduction. Grade 904L stainless steel is a non-stabilized austenitic stainless steel with low carbon content. 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 …
What is UNS N08904?
Alloy 904L (UNS N08904) is a superaustenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of process environments. The combination of high chromium and nickel content, coupled with additions of molybdenum and copper, assure good to excellent corrosion resistance.
Is Carpenter 20 the same as Alloy 20?
Alloy 20, also known as Carpenter 20, is a nickel-iron-chromium austenitic alloy that was developed for maximum resistance to acid attack, specifically sulfuric acid.
What is a20 steel?
Alloy 20 is an austenitic stainless steel developed for applications involving sulfuric acid. Its corrosion resistance also finds other uses in the chemical, petrochemical, power generation, and plastics industries.
What kind of stainless steel is uns no8904?
UNS NO8904, commonly known as 904L, is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI 316L and AISI 317L are not adequate.
What makes Alloy 904L stainless steel corrosion resistant?
Alloy 904L (UNS N08904) is a superaustenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of process environments. The combination of high chromium and nickel content, coupled with additions of molybdenum and copper, assure good to excellent corrosion resistance.
Which is the equivalent material for AISI 904L?
AISI 904L equivalent material US European Union ISO Japan China Standard Type Standard Grade (Steel Number) Standard AISI SAE; ASTM 904L (UNS N08904) EN 10088-2; EN 10088-3 X1NiCrMoCu25-20-5 (1.4539) ISO 15510
What should the annealing temperature be for 904L stainless steel?
Annealing: The recommended annealing temperatures for 904L wrought steel is 1095 °C (2000 °F). Type 304 stainless steel can handle mild foods and vegetables, but sauces and pickle liquors are more corrosive and can even cause pitting corrosion on type 316 stainless steel.
