Brinell Hardness of Gray Cast Iron

The Brinell Hardness of Gray Cast Iron constant displays the value of the Brinell hardness of gray cast iron ASTM A48 Class 40 (235 BHN). 

Brinell hardness test determines the ability of a metal to resist permanent indentation deformation through the scale of penetration of an indenter that is loaded onto a material sample. Brinell hardness is one of several definitions of hardness for materials science.

The Brinell hardness of gray cast iron is 235 Brinell hardness numbers (BHN).

Welding Calculators:

• Bend Allowance Calculator: Computes Bend Allowance based on the thickness of the material, bend angle, inside radius, and K factor.
• Weight of Aluminum Square Bars: Computes the average weight of aluminum bars based on the number and dimensions of the bar, and an average density of 2700 kg/m3 for aluminum bars.
• Aluminum Wire Deposition Rate Calculator:  Estimates the rate at which a welding wire is converted into weld metal using the electrode diameter, wire feed speed, and electrode efficiency.
• Welding Heat Input Calculator: Estimates the amount of heat or thermal energy that is introduced to a material when a weld is made using the arc voltage, current, and travel speed.
• Groove Weld Potential Root Cracking Calculator: Determines whether or not the groove weld has a potential for root cracking based on the width-to-depth ratio (1.0-1.4).
• Weight of Hot Rolled Steel Flats: Computes the average weight of steel flats based on the number and dimensions of the flats, and an average density of 7800 kg/m3 for steel flats.
• Modulus of Elasticity for Martensitic Stainless Steel: The measure of stainless steel's tendency to deform elastically when a force is applied.
• Brinell Hardness of Gray Cast Iron: Measure of gray cast iron's ability to resist permanent indentation deformation
