What does a high Brinell hardness number mean?
Brinell hardness indicates the ability of a metal to resist permanent indentation deformation. The hardness shows the material’s resistance to penetration by a spherical indenter under standardized conditions.
How do you read Brinell hardness?
A Brinell hardness value consists of the following components:
- The numeric hardness value;
- The three letters “HBW”, standing for “Hardness according to Brinell” (with hard metal ball made from tungsten carbide);
- The ball diameter in mm;
- The applied test load in kgf;
What are the grades for stainless steel?
The two most common stainless steel grades are 304 and 316. The key difference is the addition of molybdenum, an alloy which drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments. 316 stainless steel contains molybdenum. 304 stainless steel does not.
Which is harder 316 or 304?
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.
What is SUS in stainless steel?
Stainless steel is the alloy of chromium and nickel. Sometimes, it is referred as SUS, an acronym from Japanese Industrial Standards (JIS). Stainless steel has various types to meet various needs, and is used in numerous precision machine parts, bolts, and nuts.
