Steel round bar grade 1.3537 (100CrMo7-3) is a high-quality round rolled product widely used in mechanical engineering, tool manufacturing, and other industries where materials with high strength, wear resistance, and load capacity are required. This review provides details on its specifications, chemical composition, mechanical properties, applications, and features.

General Specifications

The 1.3537 steel round bar belongs to the category of alloyed steels designed for manufacturing components operating under high loads and wear conditions. Key characteristics include:

• Steel grade: 1.3537 (European EN standard) / 100CrMo7-3.
• Form of supply: Round bar with diameters ranging from 10 mm to 300 mm.
• Type of rolling: Hot-rolled or calibrated.
• Diameter tolerances: Standard or customized upon request.
• Surface finish: Rough or polished.

The 1.3537 round bar is highly versatile, suitable for various machining processes such as turning, milling, drilling, and grinding.

Chemical Composition

According to European standards, the chemical composition of 1.3537 (100CrMo7-3) steel is as follows:

• Carbon (C): 0.95–1.05%
• Chromium (Cr): 1.75–2.10%
• Manganese (Mn): 0.25–0.45%
• Molybdenum (Mo): 0.15–0.30%
• Silicon (Si): 0.15–0.35%
• Phosphorus (P): ≤ 0.025%
• Sulfur (S): ≤ 0.025%

This alloying composition ensures high strength, hardness, and wear resistance, making this steel ideal for bearings, tools, and other mechanically loaded components.

Mechanical Properties

After heat treatment (quenching and tempering), 1.3537 steel exhibits the following mechanical properties:

• Hardness (HRC): Up to 62 (after quenching).
• Tensile strength (σv): 900–1100 MPa.
• Impact toughness: High resistance to impact loads.
• Wear resistance: Ensures long service life for components.

These properties make the 100CrMo7-3 round bar an optimal choice for parts subjected to friction and high dynamic loads.
