1.7218 Steel

 

1.7218 steel standard: 1.7218 steel is a low-alloy steel defined in the European standard EN 10297-1. This standard specifies the chemical composition, mechanical properties, and application range of 1.7218 steel.

 

Specific chemical composition: The chemical composition of 1.7218 steel includes: a carbon (C) content of 0.16-0.22%, a silicon (Si) content of 0.40%, a manganese (Mn) content of 0.70-1.00%, a phosphorus (P) content not exceeding 0.035%, a sulfur (S) content not exceeding 0.035%, a chromium (Cr) content of 0.90-1.20%, a molybdenum (Mo) content of 0.15-0.25%, and iron (Fe) as its main residual element.

 

Tensile strength: The tensile strength of 1.7218 steel is 850-1100 MPa.

 

Yield strength: The yield strength of 1.7218 steel is 670-900 MPa.

 

Elongation at break: The elongation at break of 1.7218 steel is 10-20%.

 

Uses: 1.7218 steel is widely used in the manufacture of high-strength mechanical parts, such as gears, reducers, bearings, and retaining rings.

 

Status: Common states of 1.7218 steel include heat treatment, normalizing, and annealing.

 

Advantages: 1.7218 steel has good welding and thermal processing properties, and is suitable for manufacturing complex mechanical parts.

 

Disadvantages: 1.7218 steel has high strength and hardness, and is difficult to process. It is prone to serious cutting tool damage and surface cracking problems.

 

Most common forms: The most common forms of 1.7218 steel include round steel, flat steel, square steel, and pipe.

 

Comparison of national grades: The comparison of national grades of 1.7218 steel is relatively simple. Internationally, the German grade is 25CrMo4, the American grade is 4130, and the Chinese grade is 30CrMo.

 

Summary: 1.7218 steel is a low-alloy steel with high strength and good welding properties, and is widely used in the manufacture of high-strength mechanical parts. The most common forms include round steel, flat steel, square steel, and pipe. The comparison of national grades is simple, such as Germany's 25CrMo4, America's 4130, and China's 30CrMo.
