High hardness armor with extrordinary toughness properties. HSC® 500T is the world's toughest protection plate, having nominal 500 HBW hardness, for use in vehicles, buildings and many more applications.
About the claims: “Extrordinary” means extraordinary. “The world’s toughest protection plate” and “market-leading” are the mill’s own wording; ballistic performance depends on the test standard, threat, thickness and mounting, so state the protection level you need and ask for test evidence.
HSC Armour Plate – 500T Grade: Purchasing Specification
| Requirement | What to specify |
|---|---|
| Grade and specification | Armor 400 / 500, Armor 500T, HSC 500T, MIL-A-46100 or MIL-A-12560, as your specification names; say which specification and revision applies. |
| Protection level | State the threat or protection class and the ballistic test standard your project cites; thickness and hardness are chosen to meet it. |
| Dimensions | Thickness × width × length in mm or inches; number of plates or total weight. |
| Condition | Quenched plate, not intended for further heat treatment; do not heat it above the mill’s limit. |
| Cutting | Waterjet cutting is preferred because it keeps the properties of the cut edge; laser and plasma are also suitable. |
| Welding and forming | Austenitic consumables are recommended; cold bending needs generous radii and safety measures. |
| Documents | EN 10204 inspection certificate with chemistry and hardness; ballistic test reports where the specification requires them. |
Benefits of HSC 500T include:
- Market-leading steel protection
- Superior workshop properties
- Optimized solutions
- Perfect hardness/toughness balance, for combined penetration and blast protection
- Expertise in ballistic protection.
It offers vehicle designers new ways to increase protection using lighter weight designs. HSC 500T is not intended for further heat treatment.
Dimension range
HSC 500T is available in thicknesses between 3.0 and 80.0 mm. Other dimensions to be agreed with SSAB.
Mill reference: The page names SSAB for other dimensions. Confirm the mill, brand and approval status of the plate you will receive when you enquire.

How the Six Ballistic Steel Pages Differ
The six pages cover armour plate to different mill brands and military specifications. Armor and HSC grades are quenched steels of about 400 to 560 HBW sold by thickness and hardness; the MIL specifications set hardness and ballistic approval for military use. The pages differ in the grade they describe and the data they give.
| Page | What it covers | Typical use (from the pages) |
|---|---|---|
| ARMOUR | Armor 400 and 500: dimensions, tolerances, welding, bending and cutting, chemistry and typical mechanical properties | Doors, walls, bank counters and vaults, vehicles, secured containers |
| ARMOR 500T | 480–540 HBW plate, 3–80 mm, Charpy-V 32 J at −40 °C, with chemistry and tolerances | Vehicles and buildings, with combined penetration and blast protection |
| ARMOR 500 | 490–560 HBW plate and cut lengths, 2–30 mm, with thickness and flatness tolerances | Ballistic protection of high hardness |
| MIL A 46100 | Military high-hardness armour, 477–534 BHN, quenched and tempered | Stopping high-velocity projectiles, such as sniper fire |
| MIL A12560 | Rolled homogeneous armour in four classes, typical 377–415 BHN | Combat vehicles, ammunition proof testing, landmine protection |
| HSC 500T (this page) | 480–540 HBW plate, 3–80 mm, Charpy-V 32 J at −40 °C, with chemistry and thickness tolerances | Vehicles, buildings and other protection applications |
State the specification, protection level and test standard on your enquiry; armour grades are not interchangeable.

Applications for HSC Armour Plate – 500T Grade
Typical uses include doors, walls and window frames, bank counters and vaults, security vans, secured containers, shooting-gallery equipment and military vehicles. Tell us the load, temperature and service conditions so the right grade and thickness can be quoted.
Cutting, Fabrication and Welding
Champak Industries describes full and part plate/profile supply and a plasma-cutting service. Send drawings, quantities, tolerances and edge preparation for your parts. Plasma and laser cutting are suitable and waterjet is preferred, because it keeps the properties of the cut edge. Weld with austenitic consumables, avoid further heat treatment, and cold-bend only to the mill’s radius and safety guidance.
Testing, Inspection Documents and Traceability
| Requirement | What to identify in the order |
|---|---|
| Inspection certificate | EN 10204 showing grade, heat number, chemistry and hardness (the Armour Plates page mentions EN 10204-2.2) |
| Hardness | Brinell hardness range for the grade (HBW) |
| Impact test | Charpy-V temperature and energy, where the grade lists them |
| Ballistic test | Test standard, threat level and test report, if required by your specification |
| Traceability | Heat and plate number transferred to cut pieces |
