1.7039 Steel

 

1.7039 steel standard: 1.7039 steel, also known as 41CrS4 steel, belongs to the alloy steel defined in European standard EN 10083-3. The standard specifies the chemical composition, mechanical properties, and application scope of 1.7039 steel.

 

Specific chemical composition: The chemical composition of 1.7039 steel includes a carbon (C) content of 0.38-0.45%, silicon (Si) content not exceeding 0.40%, manganese (Mn) content of 0.60-0.90%, phosphorus (P) content not exceeding 0.035%, sulfur (S) content not exceeding 0.035%, Chromium (Cr) content is 0.90-1.20%, and iron (Fe) is the main residual element.

 

Tensile strength: The tensile strength of 1.7039 steel is 1000-1200 MPa.

 

Yield strength: The yield strength of 1.7039 steel is 800-1000 MPa.

 

Elongation at break: The elongation at break of 1.7039 steel is 10-18%.

 

Uses: 1.7039 steel is widely used in high-strength and high-fatigue performance components in automotive, mechanical, and aerospace fields, such as gears, crankshafts, connecting rods, and bearings.

 

State: The common states of 1.7039 steel include heat treatment, normalizing, and annealing.

 

Advantages: 1.7039 steel has good heat treatment performance, high fatigue performance, and is suitable for high-stress and high-load working environment. In addition, the steel has good machinability and stability at high temperatures.

 

Disadvantages: The welding performance of 1.7039 steel is poor, and it is prone to cracking and deformation. In addition, its price is relatively high.

 

Most common form: The most common forms of 1.7039 steel include round steel, flat steel, square steel, and tube materials.

 

Comparison of national grades: The comparison of national grades of 1.7039 steel is relatively simple. The German grade is 1.7039, the British grade is 708M40, the American grade is 5140, and the Chinese grade is 40Cr.

 

Summary: 1.7039 steel is an alloy steel with high strength and fatigue performance, widely used in automotive, mechanical and aerospace fields. The most common forms include round steel, flat steel, square steel, and tube materials. The comparison of national grades is relatively simple, such as the German 1.7039, British 708M40, American 5140, and Chinese 40Cr.
