What is the Hardness of HIND ARMOR 500? – Understanding Its Ballistic Protection Level

When sourcing steel for ballistic protection, one of the first questions buyers ask is:
“What is the hardness of HIND ARMOR 500?”

The answer is simple:
HIND ARMOR 500 is a high hardness quenched and tempered steel plate with a typical hardness range of 470 to 540 BHN (Brinell Hardness Number).

This hardness level makes it suitable for multi-hit ballistic resistance, especially against rifle rounds, armor-piercing threats, and blast fragments.

Understanding BHN Hardness in HIND ARMOR 500

BHN (Brinell Hardness Number) measures a material’s ability to resist penetration under load.

For HIND ARMOR 500, the target hardness range is 470–540 BHN, offering a balance between:

• Projectile stopping power
• Multi-hit performance
• Fabrication feasibility

This places HIND ARMOR 500 in the same performance class as global high hardness armor grades like MIL-DTL-46100 and STANAG Level 2/3 compliant steels.

Applications Where HIND ARMOR 500 Hardness Matters

Where is this hardness range critical?

Each of these applications demands high surface hardness to ensure bullet deflection, absorption, and stopping ability.

Mechanical Properties Linked to Hardness

Typical Mechanical Properties of HIND ARMOR 500 Plates:

Property	Typical Range
Hardness	470 – 540 BHN
Yield Strength	1200 – 1500 MPa
Tensile Strength	1400 – 1800 MPa
Elongation	8 – 12%

Exact values depend on plate thickness and production batch.

Standards to Fabrication (H5 to H10)

Global Standards Related to HIND ARMOR 500 Hardness

HIND ARMOR 500 is not a direct brand of international standards, but it offers material-level equivalency to several global grades in terms of hardness and ballistic resistance.

Standard / Grade	Hardness Range
MIL-DTL-46100	477–534 BHN
STANAG 4569 Level 2/3 Zones	Typically 500 BHN
EN 1522 FB6 / FB7 (Material Level)	Varies, generally 500 BHN
HIND ARMOR 500 (HSC Proprietary Grade)	470–540 BHN

 This makes HIND ARMOR 500 a suitable choice for OEMs and defense contractors needing high hardness armor steel.

Thickness Range and Plate Sizes

We supply HIND ARMOR 500 plates in thicknesses suitable for vehicle armor, infrastructure protection, and ballistic door fabrication.

Parameter	Range
Thickness	6 mm to 25 mm for most vehicle zones
Width	Up to 2500 mm
Length	Up to 12000 mm

Heat Treatment and Hardness Control

HIND ARMOR 500 plates are produced through a precise quenching and tempering process to achieve uniform hardness throughout the plate thickness.

Key Benefits of Controlled Hardness:

• Consistent multi-hit resistance
• Better ballistic performance across zones
• Improved workability compared to ultra-hard plates

Every batch undergoes hardness testing, and test reports can be provided upon request.

Cutting, Drilling, and Fabrication Tips for High Hardness Steel

Fabricating 470–540 BHN steel plates requires care.

Cutting:

• Waterjet, plasma, or laser cutting recommended
• Minimize heat-affected zones

Drilling:

• Use carbide tools with coolant flooding
• Low RPM, high feed recommended for clean holes

Welding:

• Preheat between 150°C and 250°C for plates over 10 mm
• Use low hydrogen electrodes
• Post-weld stress relief recommended for large or thick panels
