Technical Standards & Equivalent Grades

Swebor 400 and Swebor 500 Armor Plates are proprietary Swedish grades, but at Hindustan Steel Corporation, we supply equivalent high-hardness steel plates that meet similar ballistic and wear-resistance performance.

Key Technical Details:

Standard / Brand	Approximate Equivalent
Swebor 400 / 500	High hardness, low-weight armor steel
MIL-DTL-46100	U.S. High Hardness Armor Steel
EN 1522 FB6 / FB7	For architectural ballistic protection levels
HIND ARMOR 500 / HSC 500T	Hindustan Steel Corporation’s in-house alternative
STANAG 4569 Level 2/3	NATO protection level comparison for vehicles

Note: Exact equivalency depends on project requirements, plate thickness, and ballistic test conditions.
Our technical team can help you with material cross-reference and substitution planning.

Machining & Fabrication Advice

Swebor 400 / 500 equivalent armor plates can be fabricated with special care, keeping in mind their high hardness and strength.

Fabrication Tips:

Cutting:

• Best done with waterjet, plasma, or laser cutting
• Avoid thermal distortion on ballistic critical areas

Drilling:

• Use carbide-tipped drill bits
• Keep coolant flooding and slow RPM with higher feed for precision

Welding:

• Preheating is essential, especially for thicknesses above 12 mm
• Use low hydrogen electrodes (E7018/E10018 types)
• Apply post-weld stress relieving for thicker sections

Bending/Forming:

• Possible on thinner sections like 3–8 mm, but tight radii should be avoided

For armor OEMs, Hindustan Steel Corporation offers pre-fabricated shapes, laser-cut profiles, and project-specific plate kits to reduce on-site processing time.
