Type 304L stainless steel is an extra-low carbon version of the 304 steel alloy. The lower carbon content in 304L minimizes deleterious or harmful carbide precipitation as a result of welding. 304L can, therefore, be used "as welded" in severe corrosion environments, and it eliminates the need for annealing.
STAINLESS STEEL WHEN HEALTH COMES FIRST Austenitic stainless steels consist pri-marily of iron, 16 - 28 % chromium (1) and up to 35 % nickel (1). In some cases Ni can be replaced by other austenite forming ele-ments like Mn, N and Cu. Table 1 shows the principal alloying constituents of some se-lected austenitic stainless steel grades.
304/304L STAINLESS STEEL Product Description Type 304 is a variation of the base AK Steel 18-8, with a higher chromium and lower carbon content. The lower carbon content minimizes chromium carbide precipitation due to welding and its susceptibility to intergranular corrosion. In some instances Type 304 can be used in the "as-welded" condition.

release data, conducted on stainless steel in order to assess the toxicological relevance of this data to human health, to draw conclusions about the toxicity of stainless steel, and to give recommendations for the classification and labelling of stainless steel according to GHS.
Abstract. To evaluate the biocompatibility of MIM 316L stainless steel, the percentage of S-period cells were detected by flow cytometry after L929 incubated with extraction of MIM 316L stainless steel, using titanium implant materials of clinical application as the contrast.
Cytotoxicity difference of 316L stainless steel and titanium reconstruction plate. stainless steel 304l biocompatibility This investigation aimed to compare the biocompatibility of duplex stainless steel, with and without 0.2% stainless steel 304l biocompatibility
304 stainless steel has excellent resistance to a wide range of atmospheric environments and many corrosive media. It is subject to pitting and crevice corrosion in warm chloride environments and to stress corrosion cracking above about 60 C. It is considered resistant to pitting corrosion in water with up to about 400 mg/L chlorides at ambient temperatures, reducing to about 150 mg/L at 60 C.

Grade 304 stainless steel is excellent in a wide range of atmospheric environments and many corrosive media. It is subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above 60 C (approximate).
Stainless steel is used for buildings for both practical and aesthetic reasons. Stainless steel was in vogue during the art deco period. The most famous example of this is the upper portion of the Chrysler Building (pictured). Some diners and fast-food restaurants use large ornamental panels and stainless fixtures and furniture.
From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500 F. Rods made of 304/304L stainless steel contain less carbon than standard 304 for better weldability.
304 Stainless Steel Sheet, is the most popular and economical of the stainless steels. 304 Stainless Sheet offers good corrosion resistance to many chemical corrodents as well as industrial atmospheres and marine environments. 304 Stainless Sheet may become slightly magnetic when worked and is not heat treatable.
Biocompatibility of 302 SS wire parts - passivation issue? adv. 2004. Q. My company has a part formed from 302 stainless wire. After forming, it is annealed, ground, ultrasonically cleaned, passivated per ASTM 967 and dried before being shipped to us.
304 / 304L Stainless Commercial Tubing These grades of austenitic stainless steels are the most versatile and widely used stainless steels. They exhibit excellent corrosion resistance to a wide range of corrosive environments.
304H stainless steel has the higher carbon content, which makes it ideal for applications requiring good mechanical properties at elevated temperatures. It is frequently used as a construction material up to about 1500 degrees Fahrenheit, but provides improved high temperature strength when exposed to temperatures exceeding 800 degrees Fahrenheit.
What is the Difference Between 304 and 304L Stainless Steel? When it comes to variations between 304 and 304L stainless steel, an essential thing to note is the latters greater immunity to intergranular corrosion. Intergranular corrosion is the cracking that can occur along grain boundaries of steel in the presence of tensile stress.
Is 304 Stainless Steel a Good Choice for Marine Environments? Clinton offers SAE 304 stainless steel, which can also be found under the name A2 stainless steel or 18/8 stainless steel. 304 is the most popular stainless steel alloy available on the market. It is an austenite steel, meaning that it is non-magnetic in nature.
In this study, biocompatibility of 17-4 PH stainless steel foam for biomedical implant applications was investigated. 17-4 PH stainless steel foams having porosities in the range of 40-82% with an average pore size of around 600 m were produced by space holder-sintering technique. Sintered foams stainless steel 304l biocompatibility
304/304L is an austenitic stainless steel; low carbon for as-welded corrosion resistance.
Because of these characteristics, the 304L stainless steel alloy can be used in the as welded condition, even in highly corrosive conditions. Other than this slight variation in its composition 304L stainless steel is used is many of the same applications as 304, and tends to be as commonly found. Chemical Formula
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.
NKS - 304 Stainless Steel. Processing: Types 304 and 304L cannot be hardened by thermal treatment. Annealing: Heat to 1850o F to 2050 o F and cool at sufficiently high rates through 1500oF to 800oF to avoid precipitation of chromium carbides.
