The stainless steel alloy material stands out with its incredible tensile strength of approximately 621 MPa or 90 KSI . Grade 304 also has a higher operating temperature of up to 870 °C.
Is 304 a good grade of stainless steel?
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.
How strong is 304 stainless steel?
| Properties | Properties Value Comment | Hardness, Rockwell B 82 | Tensile Strength, Ultimate 621 Mpa (=90100psi) | Tensile Strength, Yield 290 Mpa (=42100psi) 0.2% YS |

Is 304 stainless steel hard or soft?
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.
What is the ultimate tensile strength of 304 stainless steel?
| Physical Properties Metric English | Tensile Strength, Ultimate 505 MPa 73200 psi | Tensile Strength, Yield 215 MPa 31200 psi | Elongation at Break 70 % 70 % | Modulus of Elasticity 193 – 200 GPa 28000 – 29000 ksi |

Which is stronger 304 or 316 SS?
The melting point of 304 stainless steel is higher than its 316 stainless steel counterpart, ranging between 2,550 – 2,650 °F or 1399 – 1454 °C. ... The stainless steel alloy material stands out with its incredible tensile strength of approximately 621 MPa or 90 KSI.
Is 304 or 430 stainless better?
304 stainless steel is the most common commercial-grade alloy. ... These two alloys are chosen for grills and barbeques for a few reasons. They both are food-safe because of their corrosion resistance: in acidic environments, the 430 is slightly more vulnerable to corrosion , but only with prolonged exposure.
How can I tell if my stainless steel is 304 or 316?
Aesthetically, there is no difference between the two; in fact, the only way to differentiate between them is to test them chemically. The main difference between 304 and 316 stainless steel is 316 SS has the addition of molybdenum .
What is the highest grade of stainless steel?
300 series is the largest group and the most widely used. Type 304 : The best-known grade is Type 304, also known as 18/8 and 18/10 for its composition of 18% chromium and 8% or 10% nickel, respectively. Type 316: The second most common austenitic stainless steel is Type 316.
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.
How can you tell if stainless steel is 304?
If the color changes from yellow to pink, we are in the presence of a stainless steel containing molybdenum (AISI 316). If the yellow stain disappears, we are in the presence of a stainless steel that does not contain molybdenum (AISI 304).
Is 304 stainless steel safe?
Food grade stainless steel is steel that met all criteria to be deemed safe for food preparation, storage and dining . The most common food grade stainless steel is Type 304. ... 304 grade stainless steel is so popular in the food industry because of its resistance to oxidization and corrosion.
Will a magnet stick to 304 stainless steel?
It is the nickel which modifies the physical structure of the steel and makes it theoretically non-magnetic . 304 stainless steel contains chromium (min. ... The fact that it is also negligibly responsive to magnetic fields means that it can be used in applications where a non-magnetic metal is required.
Can you heat treat 304 stainless?
The most popular of the 300-series steels—304 stainless steel— is revered for its very good corrosion resistance and is commonly used in cookware. Martensitic stainless steels can be hardened via heat treatment ; how hard they can get depends on their carbon content.
What is the ultimate tensile strength of stainless steel?
Ultimate tensile strength of stainless steel – type 304 is 515 MPa . Ultimate tensile strength of stainless steel – type 304L is 485 MPa.
What is the weakness of stainless steel?
Some Disadvantages of Stainless Steel
While its high melting point can be a great advantage in some ways, this quality of stainless steel also makes difficult to use in welding , and consequently, the material has limits in how it can be used in construction. Stainless steel is also not the most cost-efficient metal.
