Chemical composition % of the ladle analysis of grade 1.4307 and Standards
Alloy 304L (UNS S30403) stainless steel tube is a variation of the 18% chromium – 8% nickel austenitic alloy, the most familiar and most frequently used alloy in the stainless steel family. This alloy may be considered for a wide variety of applications and exhibits good corrosion resistance, ease of fabrication, excellent formability, and high strength with low weight.
Type 304L is a lower carbon variant of Grade 304 – the steel can be welded without the resulting issue of carbon precipitation (precipitation of chromium carbide as heat is applied during the Welding process which depletes the chromium element of the steel thus reducing its anti-corrosive/oxidation effectiveness).
As a result, Type 304L stainless steel is a sort after material for use in severely corrosive conditions. Weld annealing is only necessary in applications where stress loads are excessive.
This steel Grade is found in a variety of commercial sectors, particularly in the chemical industry.
- Low carbon content eliminates carbon precipitation in the Welding process
- Can be used in severe corrosive environments
- Weld annealing only required in high stress applications
- Very similar to Type 304

General Information

|
Principal Design Features
|
||||
|
A low carbon version of type 304 stainless. 304L is used almost interchangeably with 304 but is preferred for Welding operations. It offers a good combination of strength, corrosion resistance and fabricability.
|
||||
|
Applications
|
||||
|
The list is endless. Almost every conceivable industry uses some of this material in some way. Everything from stovetops to ball point pen barrels to flatware to fasteners has been fabricated from this alloy.
|
||||
|
Machinability
|
||||
|
Slow speeds and heavy feeds will minimize this alloys tendency to work harden. Due to long stringy chips, the use of chip breakers is advisable. Many companies now offer premium machinability grades, such as CarTech with their Project 70 and 7000 series.
|
||||
|
All fusion and resistance processes have been successfully employed in Welding 304. AWS E/ER308 or 312 filler metal is recommended. Its low carbon, means that the is less carbide precipitation at the weld boundaries resulting in stronger welds.
|
||||
|
Hot Working
|
||||
|
Forging, heading and other hot working should follow uniform heating to 2100-2300 F (1149-1260 C). Rapid cooling is necessary to attain maximum corrosion resistance in finished parts.
|
||||
|
Cold Working
|
||||
|
Readily fabricated by most cold working methods, 304L may require intermediate annealing to avoid cracking or tearing from radical deformation. Full annealing should follow any operation to reduce internal stress and optimize corrosion resistance.
|
||||
|
Annealing
|
||||
|
1850-2050 F (1010-1121 C) followed by rapid cooling.
|
||||
|
Hardening
|
||||
|
This alloy does not respond to heat treatment. Cold work will cause an increase in both hardness and strength.

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.
