What is the composition of SS 304?
Type 304 is the most versatile and widely used stainless steel. It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel. Type 304 stainless steel is an austenitic grade that can be severely deep drawn.
What is ss304 hardness?
304 steel has a Rockwell B hardness of 70; for reference, the Rockwell B hardness of copper, a soft metal, is 51.
What is the difference between 316 SS and 304 SS?
Chemical Composition 316 contains many similar chemical and mechanical properties as 304 stainless steel. To the naked eye, the two metals look the same. However, the chemical composition of 316, which is made up of 16% chromium, 10% nickel, and 2% molybdenum, is the main difference between 304 and 316 stainless steel.
Is SS 304 a specification?
It is still sometimes referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel….Physical Properties of Stainless Steel 304.
| Property | Value |
|---|---|
| Density | 8.00 g/cm3 |
| Melting Point | 1450 °C |
| Modulus of Elasticity | 193 GPa |
| Electrical Resistivity | 0.72 x 10-6 Ω.m |
Is 304 a chemical composition?
It has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. It is defined as a Chromium-Nickel austenitic alloy. Grade 304 is the standard “18/8” stainless that you will probably see in your pans and cookery tools. Grade 304L is the low carbon version of 304.
Is 304 SS Rohs compliant?
As a trusted 316 & 304 supplier, we supply fully certified and 100% traceable material that is ROHS compliant, ensuring the highest quality.
What is the difference between SS304 and ss304l?
Type 304 and 304L have very similar chemical and mechanical properties. The only difference between them is the carbon content; the 304 stainless steel has a maximum range of carbon of 0.08% whereas the 304L has a maximum range of 0.03%. This range of carbon in the steel affects the corrosion resistance of the tanks.
Is SS304 magnetic?
Austenitic Stainless Steel: Austenitic stainless steels have a high amount of austenite which makes them mostly non-magnetic. Even though grades such as 304 and 316 stainless steel have high amounts of iron in their chemical composition, austenite means they are non-ferromagnetic.
Is stainless steel 304 rust proof?
304 stainless steel is the most common form of stainless steel used around the world due to excellent corrosion resistance and value. 304 can withstand corrosion from most oxidizing acids. That durability makes 304 easy to sanitize, and therefore ideal for kitchen and food applications.
Does ss304 attract magnet?
Wrought, austenitic stainless steels, such as 304 and 316, are generally regarded as non-magnetic in the annealed condition, i.e. they are not attracted significantly by a magnet.
Is 304 SS ferrous?
A ferritic stainless steel owes its magnetism to two factors: its high concentration of iron and its fundamental structure. Both 304 and 316 stainless steels are austenitic, when they cool, the iron remains in the form of austenite (gamma iron), a phase of iron which is nonmagnetic.
What is the meaning of SS 304?
SS 304 is the abbreviation of Stainless Steel 304, which is the most widely used austenitic chromium-nickel stainless steel. Its nominal composition is 18% chromium and 8% nickel, so it is also called 18/8 stainless steel.
What is 304 stainless steel made of?
AISI 304 stainless steel (UNS S30400) is the most widely used stainless steel, containing 18-20% Cr and 8-10.5% Ni, and also known as 18-8 stainless steel.
What is the annealing temperature of 304 stainless steel?
Type 304 stainless steel annealing temperature range is 1010-1065 °C (1040 °C is recommended) and then rapidly cooled. Before annealing, the surface should be carefully cleaned, and to prevent the formation of an oxide layer during the annealing process, vacuum, hydrogen or inert gas protection must be used.
What is the difference between SS304 and AISI 304L?
SS304 is widely used in the industrial use, furniture decoration, food and medical industry, etc. AISI 304L is the low carbon version of 304 stainless steel, AISI 303 is a free-machining steel, basically a variant of 304, which increases the phosphorus (P) and sulfur (S) content and improves the machinability.
