37MnSi5 / 1.5122 Alloy Steel

Steel Round Bar 1.5122 / 37MnSi5: Specifications, Applications, and Features

Steel round bar 1.5122 (37MnSi5) is a high-quality structural material widely used in mechanical engineering and other industries due to its high strength, ductility, and resistance to mechanical loads. Its chemical composition and mechanical properties make it indispensable for manufacturing components that operate under heavy conditions. Below, we will explore the main specifications, applications, and features of 1.5122 steel.

General Specifications

Steel round bar 1.5122 (37MnSi5) belongs to the group of alloyed structural steels, characterized by increased impact toughness and deformation resistance. Key characteristics include:

• Steel grade: 1.5122 (European EN standard) / 37MnSi5.
• Form of supply: Round bar with diameters ranging from 10 mm to 300 mm.
• Type of rolling: Hot-rolled or calibrated.
• Surface finish: Rough or polished.
• Tolerances: Standard or customized (on request).

The 1.5122 round bar is easily machinable, making it versatile for manufacturing complex components.

Chemical Composition

The chemical composition of 1.5122 steel is carefully balanced to provide excellent performance characteristics:

• Carbon (C): 0.34–0.42%
• Manganese (Mn): 1.20–1.60%
• Silicon (Si): 0.60–0.90%
• Phosphorus (P): ≤ 0.025%
• Sulfur (S): ≤ 0.025%

The high manganese content ensures excellent impact toughness and wear resistance, while silicon enhances strength and heat resistance.

Mechanical Properties

After heat treatment, 37MnSi5 steel demonstrates the following mechanical properties:

• Hardness (HB): Up to 280 (as delivered), increases after quenching.
• Tensile strength (σv): 800–1000 MPa.
• Impact toughness: High resistance to dynamic loads.
• Ductility: Good machinability under both cold and hot deformation.

These characteristics make the 1.5122 steel round bar a reliable material for manufacturing components exposed to wear and heavy loads.
