Chemical composition % of the ladle analysis of grade 904L 00Cr20Ni25Mo4_5Cu NO8904 and Standards
904L domestic brands 00Cr20Ni25Mo4.5Cu. American Standard NO8904, with different purposes. C content of <= 0.02% or 0.03%. has a high chromium content and nickel content enough, the addition of copper to give it a strong acid resistance , especially chloride crevice corrosion and stress corrosion cracking are highly resistant to pitting corrosion resistance slightly better with other kinds of steel, has a good machinability and weldability. Applications: pressure vessel. the steel corrosion in sulfuric acid with a variety of applications are developed. is gradually being promoted on the market of steel.
Main features: high chromium content and nickel content enough, especially crevice corrosion and chloride stress corrosion cracking are highly resistant to pitting corrosion resistance slightly better with other kinds of steel.
Applications: sulfur, phosphorus and acetic acid treatment equipment, chemical industry, machinery manufacturing. In the pulp and paper industry and chemical industry, etc. are widely used.

Principal Design Features
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.
Heat Treatment
CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.
Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
