Product Description
Werkstoffnummer (W.Nr.) 1.2365, designated under the DIN system as X32CrMoV3-3, is a high-grade, chromium-molybdenum-vanadium hot-work tool steel. Highly prized in European and global manufacturing, 1.2365 is renowned for its excellent high-temperature strength, thermal shock resistance, and resistance to thermal fatigue cracking (heat checking).
It is the direct European equivalent to AISI H10, offering critical structural stability when tooling operates continuously at temperatures exceeding $500^circtext{C}$.
Chemical Composition (Typical Weight %)
The high content of molybdenum working alongside a deliberate silicon level provides the steel with exceptional secondary hardening capabilities and hot-yield strength.
| Carbon (C) | Molybdenum (Mo) | Chromium (Cr) | Silicon (Si) | Vanadium (V) | Manganese (Mn) |
| 0.30 0.37% | 2.60 3.00% | 2.80 3.30% | 0.10 0.40% | 0.40 0.60% | 0.15 0.45% |
Material Application by Product Form
1. 1.2365 Tool Steel Bars & Rods
Typically delivered in the spheroidized annealed condition with a maximum hardness of 229 HBW to ensure clean machinability. Round bar stock is highly specified for:
-
Extrusion Tooling: Mandrels, pressing stems, and die holders used in the hot extrusion of aluminum, copper, and brass.
-
Hot Punching & Piercing: Rods are machined into punches that must maintain high hardness and straightness without bending under continuous thermal cycles.
-
Ejector Pins & Insert Sleeves: Used within die-casting dies where mechanical movement happens under extreme heat.
2. 1.2365 Flat Block Bar & Plate
Flat blocks are typically supplied as forged or hot-rolled plates, structural blocks, or precision-cut flat profiles.
-
Die Casting Dies: Highly utilized for heavy-duty zinc, magnesium, and aluminum die-casting die blocks due to its resistance to liquid-metal erosion.
-
Hot Forging Dies: Used for forging die segments, hot-shear blades, and gripper inserts that handle heavy pounding.
-
Plastic Moulds: Applied in specialty plastic processing molds requiring high temperature resistance or processing highly corrosive/abrasive polymers.
Heat Treatment Parameters
1.2365 is a deep-hardening steel. To protect parts from distorting or cracking, uniform thermal processing is crucial:
-
Soft Annealing: Heat slowly to $750^circtext{C} - 800^circtext{C}$. Hold for a minimum of 2 hours, then cool slowly inside the furnace at a maximum rate of $10^circtext{C} - 20^circtext{C}$ per hour down to $600^circtext{C}$, followed by air cooling.
-
Hardening (Austenitizing): Preheat slowly to $500^circtext{C}$ and then $850^circtext{C}$ to minimize thermal shock. Raise to the hardening temperature of $1010^circtext{C} - 1040^circtext{C}$.
-
Quenching: Oil, vacuum nitrogen gas pressure blast, or hot bath ($500^circtext{C} - 550^circtext{C}$). Air or vacuum gas is strongly preferred for intricate flat blocks to reduce dimensional distortion.
-
Tempering: Double tempering is mandatory. Tempering must occur immediately after the steel drops below $60^circtext{C}$. Standard tempering happens between $540^circtext{C} - 650^circtext{C}$ to target a service hardness of 44 to 52 HRC.

Versatile Shape and Condition Options
DIN 1.2365 tool steel is offered in round, flat, square, and block forms, and can be delivered as rolled, rough turned, or fully machined. This flexibility ensures that you find the right material specification suitable for your project requirements, whether you need hot rolled rods for forging or polished blocks for die-making. Standard and custom lengths from 2 to 6 meters provide additional adaptability.
Exceptional Hot Work Performance
With a robust combination of Chromium, Molybdenum, and Vanadium, 1.2365 alloy steel exhibits outstanding toughness, hardness, and resistance to thermal fatigue. Its heat treatment options-annealed, hardened, and tempered-further enhance its suitability for demanding hot work applications such as plastic moulds, extrusion dies, and die casting. The steel maintains strength at elevated temperatures, making it a preferred choice in intensive industrial settings.
Reliable Supply and Quality Protection
Manufactured and supplied by experienced producers, traders, and exporters in India, 1.2365 tool steel bars are packaged using standard sea-worthy methods with bundles and end caps for safe delivery. To prevent rusting during transit and storage, each bar receives an oil coating. Orders can be tailored in quantity, length, finishing, and tolerance, with minimum order quantity negotiable as per project needs.
