What is the composition of stainless steel 304?

What is the composition of stainless steel 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 the ASTM for 304 stainless steel?

304 and 304L ASTM A240 stainless steel plate is a standard 18-8 material ā€“ meaning it contains 18% chromium and 8% nickel. 304 Stainless steel plate is one of the most versatile stainless steel materials available.

What is the material composition of stainless steel?

Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements. Stainless steel’s corrosion resistance and mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.

What is ASTM A167?

ASTM A167 : Standard Specification for Stainless and Heat-Resisting Chromium-Nickel Steel Plate, Sheet, and Strip.

What does the L mean in 304?

extra-low carbon
In grade 304 stainless, the maximum carbon content is set at 0.08%, whereas grade 304L stainless steel has a maximum carbon content of 0.03%. The ā€œLā€ in 304L can be interpreted as meaning extra-low carbon.

What is the ultimate strength of 304 stainless steel?

Ultimate tensile strength of stainless steel ā€“ type 304 is 515 MPa, while 17-4PH is about 1000 MPa. In metallurgy, stainless steel is a steel alloy with at least 10.5% chromium with or without other alloying elements and a maximum of 1.2% carbon by mass. Stainless steels, also known as inox steels or inox from French inoxydable (inoxidizable), are steel alloys, which are very well known for their corrosion resistance, which increases with increasing chromium content.

What does 304 mean in stainless steel?

Type 304 stainless steel is a T 300 Series Stainless Steel austenitic. 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 304L is the low carbon version of 304. Is stainless steel 304 food grade? Food Grade Stainless Steel 316.

What is 304 stainless steel used for?

What is 304 Stainless Steel and Where Is It Used? As the most widely used of all stainless steel, 304 stainless steel is most notably present in industrial applications and kitchen equipment. It is a highly heat-resistant grade, and offers good corrosion resistance to many chemical corrodents, as well as industrial atmospheres.

What does 304 grade mean in stainless steel?

What Does 304 Grade Stainless Steel Mean? 304 grade stainless steel is known to be the most widely used and flexible austenitic form of stainless steel. It contains 8% nickel and 18% chromium, making it ultra resistant to corrosion and oxidation. It is also highly durable and can be fabricated with ease.
