GCr9, GCr9SiMn, GCr15, and GCr15SiMn are all types of bearing steel grades commonly used in the production of bearing components. Here are the typical details of bearing steel round bars for these grades:

Material: GCr9, GCr9SiMn, GCr15, and GCr15SiMn bearing steel round bars are typically made from high-carbon chromium steel, with GCr15 being the most widely used grade. These steels contain varying amounts of carbon, chromium, and other alloying elements to provide high hardness, wear resistance, and fatigue strength.

Diameter: The diameter of bearing steel round bars can vary widely based on the specific application requirements, ranging from a few millimeters to several inches.

Surface Finish: The bars are typically supplied with a smooth, polished surface finish to ensure precision and reduce friction in bearing applications.

Hardness: Bearing steel round bars are heat-treated to achieve high hardness, typically in the range of 60-65 HRC (Rockwell hardness scale) to provide excellent wear resistance and load-bearing capacity.

Tolerance: Precision tolerances are maintained to ensure uniform diameter and straightness along the entire length of the round bars, meeting industry standards and customer specifications.

Applications: Bearing steel round bars are primarily used in the production of various types of bearings, including ball bearings, roller bearings, and thrust bearings, as well as in other high-precision mechanical components where high hardness, wear resistance, and load-carrying capacity are essential.

Product Detail

Here are the general details of 12CrMo, 15CrMo, 20CrMo, 30CrMo, 42CrMo and 35CrMo alloy steel round bars:

Alloy Composition: These alloy steel round bars contain chromium, molybdenum and other alloying elements that give the steel high strength, wear resistance and corrosion resistance.

Mechanical Properties: These alloy steel round bars have excellent tensile strength, hardenability and toughness, making them suitable for the manufacture of high-strength parts.

Surface Treatment: The surface of alloy steel round bars can be treated by grinding, polishing or plating to meet specific corrosion resistance and aesthetic requirements.

Heat Treatment: Proper heat treatment processes such as quenching and tempering are essential to achieve the hardness, strength and toughness required for alloy steel round bars.

Standards: These alloy steel round bars usually meet industry standards such as ASTM, AISI, DIN or JIS to ensure product consistency and quality.

These alloy steel round bars are suitable for applications that require high strength and wear resistance, such as the manufacture of mechanical parts such as bearings, gears, connecting rods, etc. When selecting alloy steel round bars, you should consult a material expert or supplier based on specific requirements such as strength, toughness and processability to ensure that the appropriate material is selected for the intended use.
