Hadfield manganese plates & Sheets Supplier in Mumbai-India
Hadfield Manganese Steel Plates Widely known for its work hardening properties, are amenable to high-impact wear applications or those in which scratch abrasion is encountered. These hardened steel plates enhance almost five times the hardness of mild steel and almost three times the hardness of annealed stainless steel. Due to this, one can enjoy a longer lifespan and extended protection of their equipment and facilities.
Reading the text: “Managanese” in the page title means manganese. The “five times harder than mild steel” figure refers to the work-hardened surface (about 500–550 BHN against about 120 BHN for mild steel); as delivered, at 220–250 BHN, the plate is about twice as hard as mild steel. Austenitic stainless steel is also softer than the work-hardened surface.
Hadfield Managanese Plates: Purchasing Specification
| Requirement | What to specify |
|---|---|
| Grade and standard | X120Mn12 (1.3401) or 12–14% manganese steel; say whether your drawing cites EN, DIN or the A128 Grade B-2 composition, and state the carbon and manganese range. |
| Condition | Austenitic, water-toughened (quenched) plate; it is non-magnetic and soft as delivered, and hardens only where it is worked. |
| Thickness | Properties vary with thickness; give the thickness range of your parts. |
| Cutting | Plasma, laser or waterjet cutting; oxy-fuel (flame) cutting is not suited to austenitic manganese steel. |
| Welding | Austenitic manganese consumables and low heat input; do not preheat and keep the plate cool between passes. |
| Documents | Mill test certificate (EN 10204 3.1) with chemistry and mechanical properties. |

Damaged characters: Some symbols were damaged on the original page and show as “�”. In this table the character between 1.3401 and X120Mn13 stands for the dash that joins the two designations. The current EN name is X120Mn12 (1.3401); X120Mn13 is an older or alternative form.
Chemical Analysis Typical values (% weight)
| C | Si | Mn | Mn | P |
|---|---|---|---|---|
| 1.13 | 0.40 | 13 | 0.003 | ≤ 0.20 |
Chemistry table: The second “Mn” heading should read S (sulphur, 0.003), and “P ≤ 0.20” looks too high: ASTM A128 allows 0.07% phosphorus maximum for this grade, so confirm the value with the mill.

Reading the properties: “KCV 20 �C (68 �F)” means the Charpy V-notch test at 20 °C (68 °F). Guaranteed values are the minimums; typical values are what the mill usually reaches.

How the Four Manganese Steel Pages Differ
The four pages describe the same family of austenitic manganese steel (about 12–14% manganese and 1.1–1.3% carbon), listed under different names. The steel is soft and very tough as delivered and hardens at the surface under repeated impact, so it suits crushers and impact wear better than pure sliding abrasion.
| Page | What it covers | Typical use (from the pages) |
|---|---|---|
| 12-14% | X120Mn12 / 1.3401 steel, 11.5–14% Mn, with chemistry, mechanical and physical tables | Transport parts, grizzly bars, truck bodies |
| X120MN12 | DIN 1.3401 data sheet, 12.0–13.0% Mn, properties by thickness up to 100 mm | Crusher jaws, shovel parts, impact mills, protective plates |
| MN13 | Fully austenitic, quench-annealed, non-magnetic 12–14% manganese plate | Severe surface wear with a work-hardening effect |
| HADFIELD (this page) | The same steel under its original name: about 250 BHN, work hardening to 500 BHN | Quarries, mines, foundry, concrete and brick works, scrap, automotive |
