Which hardness test is suitable for stainless steel?

What is hardness testing?

Hardness testing is used to determine the specifications of a substance without damaging the substance.

This process is very useful for testing the fracture limit and resistance of the product.

This process occurs in several ways.

The main purpose of carrying out these processes is to find out when the product is destroyed or destroyed.

What is stainless steel hardness?

Stainless steel is a corrosion-resistant and stain-free steel.

This is a very good property and is even used in the manufacture of large steel industrial machinery due to its non-corrosive properties.

In addition to these qualities, it is also very strong and resistant to dents.

Their hardiness depends on their production methods.

The hardness characteristic of stainless steel can also be defined as the resistance to the indentation process.

The higher the hardness, the harder it is for a machine to dent in its surface.

The hardness of stainless steel also tells us about the strength of the machine we need to apply to the steel to bend or find the final product.

Types of Stainless Steel Hardness Tests

In order to test the hardness of stainless steel, there are many procedures, but the common one is indentation test, in which diamond is used to check the resistance of stainless steel.

Vickers test

 In this test, pyramids made of diamonds were used.

A force of about 1 to 100 kg. Gradually applied to stainless steel.

Only apply for about 10 seconds, due to the amount of pressure, a dent will appear.

Then, count this mark with the help of a magnifying glass and record the reading in a register or on paper.

Brinell test

Used in this type of test steel itself.

A steel ball with a diameter of 10mm is placed on the stainless steel, and a weight of 3000kgf is applied.

Because of the small diameter of the ball, apply this weight continuously for 10 to 15 seconds, creating a small indentation.

This can be seen with the help of a microscope.

Then, it helps to calculate the indentation and Brinell hardness value of stainless steel.
