Manganese Steel for Safe and Lockers

Security That Doesn’t Crack — Manganese Steel for Safes, Vaults & Lockers

When it comes to high-security lockers, cash safes, vault doors, and prison equipment, protection isn’t just about thickness — it’s about resistance to penetration, drilling, and impact. That’s where High Manganese Steel Plates excel.

At Hindustan Steel Corporation, we supply non-magnetic, high-toughness Hadfield-grade steel plates (MN13 / X120Mn12 / ASTM A128) used in anti-theft applications. These plates resist mechanical and ballistic attacks by hardening under impact — making them the ideal steel for safes, ATM lockers, prison doors, and secure vaults.

Why Manganese Steel is Ideal for Security Equipment

  •  Non-magnetic – ideal for modern electronic safes and equipment
  •  Work-hardens up to 550 BHN – resists cutting, drilling, chiseling
  • Crack-resistant under repeated mechanical force or hammering
  • Used in police-grade and military-grade safe lockers
  • Thin yet strong – enables compact locker designs without sacrificing security

What Is High Manganese Steel?

Applications in Security & Defense

We supply manganese steel plates and components used in:

  1. ATM and Cash Locker Vaults
  2. Home and Office Security Safes
  3. Jewelry Safes and Bank Vaults
  4. Prison Windows, Bars, and Doors
  5. Armored Lockers in Defense Bunkers
  6. Anti-drill Panels and Impact Shields
  7. Electronic Safe Inner Linings

Each plate can be supplied in thicknesses as low as 2mm (for compact safes) and up to 20mm (for bank-grade lockers). All are cut-to-size and CNC profile-ready

Real-World Use: Manganese in Anti-Theft Applications

As per HIC Plates, prison windows and anti-theft vaults have long relied on Hadfield manganese steel for its ability to deform, not break — absorbing shock without cracking or splitting. That same property now protects jewelry safes, luxury vaults, and ATM cash compartments.

From home security safe suppliers like Jai Bharat to defense locker applications in government tenders, MN13 grade plates are a quiet but critical backbone of protection.

Manufacturing

High manganese steel is unique among wear plates. It doesn’t just resist abrasion — it transforms under it. As it gets hit, it hardens. Here’s what technical buyers, engineers, and OEMs need to know:
