41Cr4 (SAE/ ASTM/ AISI 5140) – DIN 1.7035 Steel
41Cr4 (SAE/ASTM/AISI 5140 – DIN 1.7035) steel is one of the chromium-alloyed case-hardening steels known for its high strength, good hardenability, and wear resistance. On this page, you can find detailed information about the standard equivalents, technical and mechanical properties, chemical composition, comparable grades, areas of application, and Hasçelik’s competitive pricing advantages for 41Cr4 steel.
41Cr4 is a steel grade defined according to the German DIN standard, and the code represents the chemical composition of the steel. When we break down the code:
• “41” indicates the steel contains approximately 0.41% carbon, which affects its hardenability and strength level.
• “Cr” shows that the steel includes chromium, an important alloying element that enhances wear resistance and hardenability.
• “4” refers to the steel containing approximately 1% chromium.
41Cr4 steel has equivalent grades identified in different countries and standard systems with similar compositions. While it is known as 41Cr4 – 1.7035 in the DIN (Germany) standard, it is designated as 5140 in SAE/AISI (USA), EN 10083-3 in EN (Europe), 42CD4 in AFNOR (France), and 530M40 in the BS (UK) standard. These equivalents ensure the steel is easily recognized and correctly used in international production and supply chains.
41Cr4 (1.7035) steel is designated under various standards as follows:
• DIN (Germany): 41Cr4
• SAE/AISI (USA): 5140
• AFNOR (France): 42C4
• BS (United Kingdom): 530M40
These equivalences facilitate proper recognition and usage in international procurement and production processes.
41Cr4 is a medium carbon, chromium-alloyed heat-treatable steel. Its good hardenability, high tensile strength, and wear resistance make it a reliable choice for applications requiring strong mechanical properties. It performs exceptionally well in components requiring both surface hardness and internal toughness.
This steel grade can achieve high surface hardness through heat treatments using water or oil. It also offers good machinability and is suitable for machining processes.
• High tensile and yield strength after heat treatment
• Good impact toughness and resistance to dynamic loads
• Excellent machinability, suitable for machining and automation systems
• Suitable for heat treatment applications such as carburizing, induction hardening, and tempering
41Cr4 steel is a chromium-alloyed construction steel known for its mechanical strength and heat treatment capability. The alloying elements in its composition define the steel’s hardenability, toughness, and wear resistance. In particular, its carbon and chromium content directly affect its application areas and heat treatment behavior.
According to EN 10083-3:2006 standards, the approximate chemical composition of 41Cr4 steel is as follows:
• Carbon (C): 0.38 – 0.45%
• Manganese (Mn): 0.60 – 0.90%
• Chromium (Cr): 0.90 – 1.20%
• Silicon (Si): 0.10 – 0.40%
• Phosphorus (P): max. 0.025%
• Sulfur (S): max. 0.035%
Thanks to its medium carbon and chromium-alloyed composition, 41Cr4 is widely used in applications where high mechanical strength is required through case hardening. Its high tensile strength, good wear resistance, and balanced toughness make it a reliable material for components exposed to impact or rotational forces.
However, it’s important to note that, like all alloyed steels, 41Cr4 performs as expected only when correct heat treatment, sizing, and machining practices are followed. Improper use or unsuitable heat treatments for the application may negatively affect its performance.
Common applications of 41Cr4 steel include:
• Automotive Industry:
Axles, shafts, flywheels, differential shafts, gear wheels, and pins – especially rotating and impact-loaded components.
• Machinery Manufacturing:
Gears, crankshafts, rings, connectors, and load-bearing parts.
• Agricultural Equipment & Construction Machinery:
Intermediary parts and connectors requiring high mechanical strength.
• Energy and Power Transmission Systems:
Shafts carrying torque and rotational force, coupling parts, ring gears.
• General Engineering Components in Quenched and Tempered Condition:
Used in the production of special parts requiring a hardened surface and tough core.
At Hasçelik, we help our customers select the most suitable steel grade according to their final application.
At Hasçelik, our 41Cr4 grade steel is produced with our modern steelmaking infrastructure and process control systems in compliance with international standards. During production, we apply various metallurgical processes to enhance steel quality and meet customer requirements:
• Vacuum Degassing (VD) is applied to minimize dissolved gases in the steel structure, resulting in a more homogeneous and higher-quality material.
• Finishing operations are then conducted, including crack inspection and control for surface and internal defects.
In this way, we produce 41Cr4 products that offer reliable, high-performance, and sustainable solutions from both mechanical and microstructural perspectives.
The pricing of 41Cr4 steel depends on several criteria:
• Required diameter
• Length of the products
• Desired tonnage
• Special processing requirements as per customer specifications
To receive the most accurate price quote, simply share the specifications of the product you need.
