What is 1.6582 (34CrNiMo6)
1.6582 is a high-strength chromium-nickel-molybdenum quenched and tempered steel with excellent strength and toughness. It is characterized by good hardenability and high load-bearing capacity and maintains its reliable mechanical properties even in larger cross-sections.
When a higher nickel content, enhanced wear resistance, and greater load-bearing capacity are required, material grade 1.6580 (30CrNiMo8) represents a high-performance alternative.
1.6582 is popularly known as AISI 4340.

Form of supply and availability of 1.6582
In stock
Immediately available from stock
Form of supply
Flat, forged, quenched and tempered
Sawn blank
The processing with the saw is a mechanical processing of the material, which results in a significantly lower unintended deformation and increased hardness for the existing structure, such as the thermal cutting.
Thus, the machined workpiece has a homogeneous structure even at the edge, which does not change in the continuation of the material.
This circumstance allows immediate finishing of the workpiece with milling or drilling . So it is not necessary to anneal the material or make a similar operation beforehand.

Frequently asked questions about material 1.6582:
Material 1.6582 is known under the chemical designation 34CrNiMo6 according to DIN/EN and corresponds internationally to the American grade 4340 (AISI/SAE), the British grade 817M40 (BS), and the French grade 35NCD6 (AFNOR).
It is the standard material for highly stressed components in automotive engineering, mechanical engineering, and drive technology.
No. With a chromium content of only approx. 1.5%, the material is not stainless. When exposed to moisture, water, or chemicals, it can quickly develop rust and therefore requires surface protection (such as coating, electroplating, or nitriding) for use in humid environments.
