Product Description

General Properties

Alloy 304L is a T-300 series austenitic stainless steel, which has a minimum of 18% chromium and 8% nickel. Type 304L has a carbon maximum of 0.030. It is the standard “18/8 stainless” that is commonly found in pans and cooking tools. Alloys 304L is the most versatile and widely used alloy in the stainless steel family. Ideal for a wide variety of home and commercial applications, Alloys 304L exhibits excellent corrosion resistance and has a high ease of fabrication, outstanding formability. The austenitic stainless steels are also considered to be the most weldable of the high-alloy steels and can be welded by all fusion and resistance welding processes.

Performance & Processing

Corrosion Resistance

Resistance to corrosion in oxidizing environments is a result of the 18 to 19% chromium that the 304 alloys contain.
Resistance to moderately aggressive organic acids is a result of the 9 to 11% nickel that the 304 alloys contain.
At times, alloy 304L may show a lower corrosion rate than the higher carbon Alloy 304; otherwise, the 304, 304L, and 304H perform uniformly in most corrosive environments.
Alloy 304L is preferred for use in environments sufficiently corrosive to cause intergranular corrosion of welds and heat-affected zones on susceptible alloys.

Heat Resistance

Good oxidation resistance in intermittent service to 1600°F and in continuous service to 1690°F.
Continuous use of 304 in the 800-1580°F range is not recommended if subsequent aqueous corrosion resistance is important.
Grade 304L is more resistant to carbide precipitation and can be heated into the above temperature range.

Welding Characteristics

Excellent welding properties; post-weld annealing is not required when welding thin sections. Two important considerations in producing weld joints in the austenitic stainless steels are:

Preservation of corrosion resistance
Avoidance of cracking

Machinability

The use of chip breakers is advised since the chips can be stringy. Stainless steel work harden rapidly; heavy positive feeds, sharp tooling, and a rigid set-up should be used below the work-hardened layer resulting from previous passes.

Processing & Forming

Hot Forming: To forge, heat uniformity to 2100 / 2300 °F. Do not forge below 1700 °F. Forging can be air cooled without danger of cracking.

Cold Forming: Its austenitic structure allows it to be deep-drawn without intermediate annealing, making this the stainless steel grade of choice in the manufacturing of sinks, hollow-ware and saucepans. These grades work harden rapidly. To relieve stresses produced in severe forming or spinning, parts should be full annealed or stress relief annealed as soon as possible after forming.

Frequently Asked Questions (FAQ)

What are the primary characteristics of Alloy 304L stainless steel?

Alloy 304L is a T-300 series austenitic stainless steel containing at least 18% chromium and 8% nickel, with a maximum carbon content of 0.030%. It is highly versatile, has excellent corrosion resistance, high ease of fabrication, and outstanding formability.

What standards does Alloy 304L comply with?

Alloy 304L complies with international standards including UNS S30403, ASTM/ASME S30403, EURONORM 1.4303, AFNOR Z2 CN 18.10, and DIN X2 CrNi 19 11.

In which applications is 304L stainless steel sheet commonly used?

It is widely used in food processing equipment (brewing, milk processing, winemaking), kitchen benches and appliances, architectural trim, automotive/aerospace structures, chemical containers, heat exchangers, and marine fasteners.

Why is 304L preferred over standard 304 for welding?

Alloy 304L has a lower carbon limit (0.030% max), making it highly resistant to carbide precipitation during heating. This property prevents intergranular corrosion in weld-affected zones, meaning post-weld annealing is often not required for thin sections.

What surface finishes are available for 304/304L stainless steel sheets?

Available finishes include No.1 (hot rolled, heat treated, and pickled), No.2D, No.2B (bright cold rolled), BA (bright annealed), No.3, No.4 (satin/brushed), 240#, 320#, 400#, HL (hairline), No.6, No.7, and No.8 (highest reflectivity mirror finish).

What is the temperature limit for the heat resistance of 304L?

Grade 304L has good oxidation resistance up to 1600°F (870°C) for intermittent service and up to 1690°F (920°C) for continuous service. However, continuous use in the 800-1580°F range is not recommended if subsequent aqueous corrosion resistance is critical.
