Products Specification of  Steel Plate

41Cr4 steel is a robust alloy that surpasses C45 steel in hardenability, making it apt for surface hardening techniques. It has superior mechanical properties, including toughness and wear resistance, which make it pivotal in machinery manufacturing. This article explores the technical specifications, properties, and applications of 41Cr4 steel. It highlights its versatility and relevance in producing mechanical parts for medium load and speed applications.

Overview

41Cr4/1.7035 Steel, with its notable mechanical properties such as enhanced toughness, plasticity, and wear resistance, holds a significant place in the machinery manufacturing industry and is commonly provided in a quenched and tempered state. This steel grade’s machinability and tolerance requirements are precise and critical to its performance.

Heat treatment techniques such as quenching and tempering processes enhance the mechanical properties of 41Cr4/1.7035 steel. In comparison with other steel grades, it exhibits superior hardenability and is highly amenable to surface hardening methods, including induction hardening and flame hardening. These methods increase the steel’s surface hardness, thereby improving wear resistance while maintaining a tough core.

The machinability of this steel grade is also of considerable importance. A careful balance between hardness and machinability is essential to ensure that the steel can be efficiently processed into final components. The steel’s high machinability, coupled with its precise tolerance requirements, contribute to its widespread use in the machinery manufacturing industry.

41Cr4 is a steel for quenching and tempering recommended for components with strength requirements lower than the steel 42CrMo4

Reference standard: DIN EN ISO 683-2 standard (formerly EN 10083-3).

Equivalent Materials

Equivalents to this material are found in several international standards, including GB 3077:40Cr in China, ASTM A29:5140 in the USA, JIS G4104:SCr440 in Japan, and BS970:530M40 in the UK. A comparative analysis of these standards is integral to material selection.

The material’s characteristics can be broken down as follows:

1. GB 3077:40Cr from China is known for its high wear-resistance and high-temperature strength.
2. ASTM A29:5140 from the USA has a good balance of strength and ductility, making it an excellent choice for applications requiring high stress.
3. JIS G4104:SCr440 from Japan is renowned for its high toughness and impact resistance.
4. BS970:530M40 from the UK possesses high tensile strength and good wear resistance.

The performance comparison of these materials offers various substitution options. However, the application considerations for these materials differ due to their varying mechanical properties. Therefore, understanding these differences is critical when considering substituting one steel for another in specific applications. These materials’ suitability for a particular application should be confirmed by thorough testing and analysis.

Ultimately, the selection of equivalent materials should be guided by the intended application’s specific requirements.
