DIN 17243 is a historical German technical standard titled "Weldable heat-resisting steel forgings and rolled or forged steel bars". It defines the delivery conditions and technical requirements for materials used in high-temperature environments, such as power plant components and pressure vessels. Key Technical Overview

This standard applies primarily to steel products designed to withstand high operational temperatures while maintaining weldability.

Scope: Covers forgings, hot pressed parts, and rolled or forged steel bars.

Applications: Essential for the manufacturing of steam boiler plants, pipework, and pressure vessels.

Properties: Includes technical delivery conditions for mechanical strength at elevated temperatures, creep limit, and creep rupture stress. Common Material Grades

Historically, several well-known steel grades were categorized under DIN 17243, including:

C22.8 (1.0460): A common carbon steel often used for flanges.

X20CrMoV 121 (1.4922): A high-alloy heat-resisting steel for critical applications.

18CrMo4 (1.7243): Used for advanced parts like gears and shafts operating under 250°C. Status and Replacements

It is important to note that DIN 17243 has been withdrawn and superseded by European (EN) standards as part of technical harmonization. Standard Type Current Replacement / Successor Steel Forgings DIN EN 10222-2 (Steel forgings for pressure purposes) Steel Bars

DIN EN 10273 (Hot rolled weldable steel bars for pressure purposes)

Note: There is also a modern DIN EN 17243:2020 standard, but it is unrelated to heat-resisting steels; it covers Cathodic protection of internal surfaces of metallic tanks. Where to Find the PDF

In the world of high-pressure engineering, is more than just a technical document—it is the historical blueprint for the "heart" of industrial power plants. While now largely superseded by modern European standards like DIN EN 10222-2 DIN EN 10273

, it remains a vital reference for maintaining older infrastructure. The Origin: Forged in Heat

The story of DIN 17243 begins in the high-heat environments of the late 20th century. Published by the

German Institute for Standardisation (Deutsches Institut für Normung)

, this standard was developed to define the "Technical Delivery Conditions" for weldable, heat-resisting steel forgings and rolled bars. DIN 17243 is a historical German technical standard

At its core, it was designed for components that operate where most materials fail: under the intense thermal stress of steam boiler plants, pipework, and pressure vessels. The Protagonists: The Steel Grades

Every great story has characters, and in DIN 17243, these are the specific steel alloys. Each was engineered with a unique set of "mechanical superpowers": C22.8 (1.0460):

The reliable workhorse. A carbon steel used for flanges and fittings, known for its balance of weldability and strength.

The heat-resistant veteran, capable of enduring elevated temperatures without losing structural integrity. X20CrMoV121:

The specialist, used in advanced applications requiring high creep resistance over thousands of hours. The Conflict: Creep and Stress The "villain" in this narrative is

—the slow, permanent deformation of metal under constant stress at high temperatures. DIN 17243 provided the essential data to fight this, including guideline values for 1% creep limits and creep rupture stress for up to 200,000 hours.

Engineers used these "PDF blueprints" to ensure that a steam pipe wouldn't burst after ten years of service, protecting both the machinery and the people working near it. The Legacy: A Standard in Transition Though the official status of DIN 17243 is now superseded

DIN 17243 is a historical German standard specifying technical delivery conditions for wrought steels with high temperature properties intended for use in the construction of boilers, pressure vessels, and pipelines.

While it has been largely superseded by European standards (EN 10222 and EN 10273), it is still frequently referenced in legacy engineering projects and maintenance. Overview of DIN 17243

This standard covers forged or rolled products (like bars and rings) that must maintain strength and creep resistance at elevated temperatures.

Steel Grades Covered: Common grades include C22.8 (1.0460), 15Mo3 (1.5415), and 13CrMo4-4 (1.7335).

Key Applications: High-pressure steam pipes, valve bodies, and boiler components.

Manufacturing Process: It mandates specific smelting methods (typically basic oxygen or electric furnace) and rigorous heat treatment (normalizing or quenching and tempering) to ensure grain stability. Current Status and Replacements

If you are working on a modern project, you likely need the current EN equivalents rather than the retired DIN 17243. EN 10222-2: For steel forgings for pressure purposes.

Part 4: Comparison – DIN 17243 vs. DIN EN 10277-5

| Feature | DIN 17243 (Old) | DIN EN 10277-5 (Current) | |---------|----------------|--------------------------| | Scope | Free-cutting steels, quenched & tempered | Bright steel products, including quenched & tempered free-cutting steels | | Steel grades | 1.0711, 1.0715, 1.0718, 1.0722 | Includes above plus 11SMn30, 11SMnPb30, 35S20, 46S20 | | Heat treatment conditions | +N (normalized), +QT (quenched & tempered) | +N, +QT, +A (annealed), +AC (as-cooled) | | Dimension limits | Up to 250 mm diameter | Up to 310 mm diameter (bright bars) | | Tolerances | Based on DIN 1013 | Based on EN 10278 (modern tighter tolerances) | | Status | Withdrawn (no legal validity) | Active, legally binding in all CEN countries |

Bottom line: If you quote DIN 17243 in a drawing or contract, it is considered obsolete. Update your specifications to DIN EN 10277-5 or EN 10083-3.

🔍 What Is DIN 17243?

DIN 17243 is a withdrawn German standard that specified technical delivery conditions for freely machinable steels — specifically, automaton steels (e.g., 9SMn28, 9SMnPb28). These are steels with added sulfur or lead to improve machinability for high-speed automatic lathes.

It was originally issued by Deutsches Institut für Normung (DIN) and covered:

Chemical composition
Mechanical properties
Tolerances and surface quality
Delivery conditions (bars, wire rods)

Important: This standard has been superseded — mainly by EN 10277 (bright steel products) and EN 10087 (free-cutting steels). DIN 17243 is no longer active for new designs.

Historical Context: Why DIN 17243 Matters (Even Retired)

DIN 17243 was originally published by Deutsches Institut für Normung (DIN) to cover hot-rolled, unalloyed, and alloyed spring steels. These steels were designed to be formed at high temperatures (typically between 850°C and 1050°C) and then quenched and tempered to achieve high elastic limits and fatigue resistance.

Q5: My customer insists on "DIN 17243" certification. What should I do?

A: Explain that DIN 17243 is obsolete. Offer to deliver material according to EN 10089 + an equivalency certificate that maps the old grade to the new standard. Most quality managers will accept this.
