What is the Brinell hardness of 316 stainless steel?
217
Mechanical Properties of 316 and 316L Stainless Steel Plate 316 stainless steel plate has a 40\% elongation. On the Brinell hardness scale 316 stainless steel plate has a hardness of 217 and a Rockwell B hardness of 95.
What is nitronic material?
Nitronic is the trade name for a collection of nitrogen-strengthened stainless steel alloys. They are austenitic stainless steels.
What is the hardness of 304 stainless steel?

How do you determine the hardness of stainless steel?
Generally, the full load is applied for 10 seconds approximately. Then, the area of the indentation mark is calculated by means of a microscope. Finally, the load is divided by the square millimeters of the area to obtain the Vickers hardness number of the material.
What is the material of inductor in Brinell hardness test?
Explanation: Hardened steel ball is used in Brinell test. But tungsten carbide ball is used in case of very hard metals. Diamond indenter is used in the Rockwell test.
What is the difference between 316 and 316L?
The key difference between 316 and 316L stainless steel is the carbon content. While 316 has a maximum carbon content of 0.08\%, 316L has a maximum carbon content of only 0.03\%.
Is 316 stainless steel ferritic?
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 difference between Nitronic 50 and 60?
Nitronic alloys provide outstanding corrosion resistance. Nitronic 50 is a corrosion-resistant metal with low magnetic permeability. Generally considered an all-purpose metal, nitronic 60 is oxidation resistant and tolerates extreme wear and galling.
What type of material is Nitronic 60?
Nitronic 60 is truly an all purpose metal. This fully austenitic alloy was originally designed as a temperature alloy, and subsequently has good high temperature properties for temperatures around 1800ºF. The oxidation resistance of Nitronic 60 is similar to Type 309 S.S., and far superior to Type 304S.
What is the difference between 304 and 316 stainless steel?
The simple answer is 304 contains 18\% chromium and 8\% nickel while 316 contains 16\% chromium, 10\% nickel and 2\% molybdenum. The molybdenum is added to help resist corrosion to chlorides (like sea water and de-icing salts).
How is Brinell hardness number (BHN) calculated?
The test is achieved by applying a known load to the surface of the tested material through a hardened steel ball of known diameter. The diameter of the resulting permanent impression in the tested metal is measured and the Brinell Hardness Number calculated as. BHN = 2 P / (π D (D – (D 2 – d 2) 1/2)) (1) where. BHN = Brinell Hardness Number.
What is the difference between Brinell and Vickers hardness test?
The Brinell hardness test generally uses a steel ball 10 mm diameter which is pressed into the surface under a load of 30 kN. In the Vickers hardness test, a pyramid shaped indenter is pressed into the surface, usually under a load of 500 N.
What are the equipment used for Brinell hardness testing?
The equipment used for Brinell Hardness Testing are: Brinell microscope to measure the generated impression. The Brinell Hardness Testing Machine (Fig. 1) consists of a loading system that includes leavers, weights, hydraulic dashpot, and plunger enclosed in the body of the machine. The test material is kept on the adjustable anvil.
What is the difference between Brinell hardness and Meyer hardness?
The difference between these tests is that the Brinell hardness is equal to the ratio of the maximum load to the whole area of the plastic imprint, while the Meyer hardness is equal to the ratio of the maximum load to the projection of the contact region onto the boundary plane.
