What is AISI 302 steel?

Material Information Alloy 302 is a general purpose austenitic stainless steel with a face centered cubic structure. It is essentially non-magnetic in the annealed condition and can only be hardened by cold working.

What is the difference between 301 and 302 stainless steel?

Being more stable than 301 stainless steel, 302 reflects a less noticeable, but still significant work-hardening response. This alloy’s corrosion resistance makes it effective for use in the food, dairy, and chemical industries. 302 is also useful in cold rolled temperatures for spring and stamping applications.

How hard is 302 stainless steel?

Type 302 is corrosion resistant in many environments, and the corrosion properties are similar to that of 304/304L stainless steel….Type 302 (UNS S30200) in Coil Form.

Property 302
Yield Strength, min. (ksi) 30
Tensile Strength, min. (ksi) 75
Elongation, min. (%) 40
Hardness, max. (Rb) 92

What is the difference between 304 and 302 stainless steel?

The 302 material has 0.15% carbon, 17% minimum chromium and 8% minimum nickel in the composition. The 302 material has higher carbon content compared to the 304 which makes it tougher than 304. While the 302 is more tough and stronger, the 304 material is more ductile.

What is the difference between 302 and 316 stainless steel?

Stainless Steel 316 is nearly identical in physical properties and heat resistance to SS 302. SS 316 provides additional corrosion resistance, particularly against pitting, due to its molybdenum chemical content. SS 316 has lower magnetism than Type 302. This stainless grade is also not hardenable by heat treatment.

Is code 304 stainless steel?

Grade 304 is a standard “18/8” stainless. It is the most versatile and most widely used stainless steel available, even though a wide range of alternatives are available; and has excellent forming and welding characteristics.

Is 304 or 302 steel better?

The chemistry of the alloys i.e. austenitic stainless steel grade 302 and grade 304 are almost similar. The only difference in their chemistry is the higher content of carbon, which gives grade 304 better hardness.

Does 302 stainless steel rust?

Rust Resistant 302 stainless steel is an alloy of nickel and iron, which means that all the properties of iron, including rust, have been watered down. Just like 6061 aluminum, 302 stainless does not rust, which makes it one of the most suitable metal grades in the construction industry.

How hard is 304 stainless steel?

304 steel has a Rockwell B hardness of 70; for reference, the Rockwell B hardness of copper, a soft metal, is 51. Simply put, 304 steel is not as hard as some of its stainless steel brothers such as 440 steel (see our article on 440 steel for more information), but still holds its own as a tough general purpose steel.

Which steel is better 304 or 202?

In comparison to grade 202, the alloy of stainless steel 304 contains nickel between 8% to about 10.5%, which is almost two times more than the former. This is why the expense of manufacturing austenitic stainless steel alloy 304 is higher than the grade 202.

Is 304 stainless steel 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.

What are the properties of AISI 301 stainless steel?

AISI 301 Stainless Steel (UNS S30100) AISI 301 stainless steel (UNS S30100) is the most susceptible to cold deformation strengthening among conventional austenitic stainless steels. Its work hardening rate is extremely high, with each increase in the amount of cold work, the tensile strength and yield strength will increase significantly.

What is the P content of AISI type 303?

The P content of type 303 and 303Se is ≤0.20%, plus 0.15% of Se or S for free machining. These elements are not conducive to weldability and may cause severe hot cracking of the weld metal.

What kind of stainless steel is Type 302?

Type 302 is a higher carbon, earlier version of Type 304 stainless steel, and many 302 applications have switched to Type 304 with the improvements in melting technology. Type 302 is non-magnetic in the annealed condition but becomes magnetic as a result of cold working.

What is the chemical composition of SS 301?

SS 301 material chemical composition is listed in the following table. Datasheet 1, The table below shows AISI 301 stainless steel composition. ASTM 666: Standard Specification for Annealed or Cold-Worked Austenitic Stainless Steel Sheet, Strip, Plate, and Flat Bar
