4140 alloy steel

4140 alloy steel is generally harder and stronger than carbon steel. It is commonly used in the manufacture of gears, axles, shafts, and other high-stress components in the automotive, aerospace, and industrial sectors. It equires additional surface treatment or coatings to protect against corrosion in certain applications.

4130 Alloy Steel

4130 Alloy Steel is commonly used in the aerospace, automotive, and oil and gas industries, as well as in bicycle frames and other high-performance applications.

4340 Alloy Steel

4340 Alloy Steel can be heat treated to a wide range of hardness levels, which allows it to be used in applications where hardness and wear resistance are important.

A514 alloy steel

A514 alloy steel is known for its high yield strength and toughness, which makes it ideal for applications that require high strength and durability.

1215 Alloy steel

Alloy steel 1215 is a free-cutting alloy that is known for its high machinability and excellent finish. It is often used in the manufacture of screw machine parts, such as gears, bushings, and shafts. It is not as strong as 4140 or 4340.

1.7220 ( 34CrMo4 or SCM435)

1.7220 is an ideal material for applications that require high strength and durability

1.7131 Alloy steel is commonly used in as gears, shafts, axles, and other mechanical parts. It can also be used for surface hardening treatments such as carburizing, nitriding, or induction hardening to further improve its properties.
