Product Introduction

“30CrMnSi” round steel is an alloy structural steel, usually supplied in a circular cross section.It is composed of carbon (C), chromium (Cr), manganese (Mn) and silicon (Si) and other elements, and has certain strength, hardness and wear resistance.resistance.

1）Composition：

. The carbon content is about 0.28% to 0.34%, which provides good strength and toughness.

. The chromium content is usually between 0.80% and 1.10%, which helps to improve hardness and corrosion resistance.

. The manganese content is about 0.80% to 1.10%, which can enhance the strength and toughness of steel.

. The silicon content is usually between 0.17% and 0.37%, which helps to improve the oxidation resistance and hardness of steel.

• Physical properties：

. Density: About 7.85g/cm3, which belongs to the category of ordinary steel.

. Melting point: about 1420-1460 degrees Celsius.

. Magnetism: it is a ferromagnetic material, which is easily magnetized

Use：

30CrMnSi round steel is commonly used in the manufacture of mechanical parts, engineering components and tools, especially when certain strength and wear resistance are required.

It is suitable for manufacturing parts that require high carrying capacity and fatigue resistance, such as bearings, gears, pins, rollers, etc.

In some structural projects that require high strength and impact resistance, 30CrMnSi round steel may also be used as a structural material.

Classification By Size：

As a common metal material, Alloy round steel is widely used in construction, machinery manufacturing, aerospace and other fields.

1. Diameter size: The diameter of Alloy round steel refers to the section diameter of round steel, which is also one of the most common size descriptions. According to the needs of use, the diameter can be selected in various sizes, from small diameter to large diameter, the specific sizes are as follows: – 3mm – 4mm – 5mm – 6mm – 8mm – 10mm – 12mm – 16mm – 20mm – 25mm – 30mm – 40mm – 50mm – 60mm – 70mm – 80mm – 90mm – 100mm

2. Length dimension: In addition to the diameter, the length of the round bar is also an important dimension parameter. Different use scenarios and projects require different lengths of round steel. The general lengths are as follows: – 1m – 2m – 3m – 4m – 5m – 6m – 7m – 8m – 9m – 10m
