In the annealed condition it is essentially non-magnetic and becomes slightly magnetic with the application of cold work. Type 304L Stainless Steel is preferred in welding applications to exclude the formation of chromium carbides during cooling in the heat affected region of the weld. These alloys represent an excellent combination of corrosion resistance and fabricability.

Engineering Thermal Properties of Metals, Conductivity, Thermal Expansion, Specific Heat Data - Metals in general have high electrical conductivity, high thermal conductivity, and high density. Typically they are malleable and ductile, deforming under stress without cleaving.
AISI 304L (S30403) Stainless Steel. The graph bars on the material properties cards further below compare AISI 304L stainless steel to: wrought austenitic stainless steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
The overall heat transfer coefficient of metals is determined by factors in addition to the thermal conductivity of the metal. The ability of the 18-8 stainless steel pipe grades to maintain clean surfaces often allows better heat transfer than other metals having higher thermal conductivity.
Temperature Effects on the Mechanical Properties of Annealed and HERF 304L Stainless Steel B.R. Antoun Sandia National Laboratories P.O. Box 969 Livermore, CA 94551 Abstract The effect of temperature on the tensile properties of annealed 304L stainless steel and HERF 304L stainless steel forgings was determined by completing experiments over the
Type 304 stainless steel is an austenitic grade that can be severely deep drawn. This property has resulted in 304 being the dominant grade used in applications like sinks and saucepans. Type 304L is the low carbon version of 304. It is used in heavy gauge components for improved weldability.
Tensile properties at elevated temperatures show no effect of internal hydrogen (thermal precharging) except for a slight decrease in reduction of area for temperatures from ambient to ~900 K and modest solute hardening near 600 K, Figures 188.8.131.52 and 184.108.40.206.
304 Stainless Steel. Stainless steel 304 is an austenitic grade that can be severely deep drawn. This property has resulted in 304 being the dominant grade used in applications like sinks and saucepans. 304L Stainless Steel. Type 304L is the low carbon version of Stainless steel 304. It is used in heavy gauge components for improved weldability.
Typical uses for Type 304L Stainless Steel. Type 304L is used primarily in welding applications due to the low carbon content which reduces the carbide precipitation. Formability. Type 304 can be easily formed into most shapes. Magnetic Properties. Is generally non-magnetic and becomes slightly magnetic when cold-worked.
304 Stainless Steel Properties 304 stainless steel is non-magnetic and exhibits high resistance to corrosion and oxidation against atmospheric, chemical, petroleum, textile, and food industry sources. It has good drawability the combination of low yield strength and high elongation permits fabrication into complex shapes.

Alloy 304/304L (UNS S30400/S30403) is the most widely utilized 18-8 chromium-nickel austenitic stainless steel. It is an economical and versatile corrosion resistant alloy suitable for a wide range of general purpose applications. It is common practice for 304L to be dual certified as 304 and 304L.
the higher thermal conductivity of foil compared to powder. In this study, 304L stainless steel parts were built by the LFP process in an inert shielding gas environment with a dual-laser system. The mechanical properties of the fabricated partswere measured and compared with the original 304L foil, as well as 304L parts fabricated by the
304 / 304L stainless steel, also known as 18/8 stainless and often referred to as 302, is the most common stainless steel. 304 stainless steel contains a higher chromium and lower carbon content than other variations of type 302. It can be used in an "as welded" condition, while 302 must be annealed.
This combination of properties is the reason for the extensive use of these alloys which represent nearly one half of the total U.S. stainless steel production. The 18-8 stainless steels, principally Alloys 304, 304L, and 304H, are available in a wide range of product forms including sheet, strip, and plate.
Types 304 and 304L are the most versatile and widely used of all the stainless steels. Their chemical composition, mechanical properties, weldability and corrosion/oxidation resistance provides the best all-round performance at relatively lower cost. These have excellent low-temperature properties and respond well to hardening by cold working.
