Steel / SCM415 / Lathe machining / Carburizing and quenching

Steel / SCM415 / Lathe machining / Carburizing and quenching

Minimum half-day estimate / Carburizing and quenching treatment of shaft (iron/SCM415)

We have manufactured only two shafts. We used SCM415 steel and applied carburizing hardening. The hardness is high at HRC (Rockwell hardness) 52 or higher. Carburizing hardening is a process that hardens the surface layer to enhance wear resistance while keeping the interior soft and maintaining toughness. Since carbon is added, it is generally applied to low-carbon steel and is commonly used for components such as shafts. Additionally, our in-house quality control department is equipped with a Rockwell hardness testing machine, allowing us to deliver quality-assured products that have been checked for precise dimensions, geometric tolerances, and hardness. We specialize particularly in machining parts made of iron, aluminum, and stainless steel that are palm-sized. If you are considering a comprehensive solution from processing to hardening and polishing, please try our quotation.

[Processing Technology] Vacuum Carburizing (Direct Carburizing)

[Processing Technology] Vacuum Carburizing (Direct Carburizing)

Since there are no grain boundary oxidation or carburization irregularities on the surface layer, it is also possible for the inner surface of the pores! Quality improvement can be expected.

"Vacuum carburizing hardening" is a carburizing hardening method conducted in a vacuum furnace. Acetylene gas supplied into the furnace undergoes thermal decomposition, and the carbon generated penetrates and diffuses from the surface. In addition to the carburizing effect, there is no grain boundary oxidation or carburizing unevenness in the surface layer, making it possible for the inner surfaces of pores as well. Moreover, since it finishes with a bright luster, quality improvement can be expected compared to conventional carburizing hardening. 【Features】 ■ Carburizing hardening method conducted in a vacuum furnace ■ In addition to the carburizing effect, it allows for the inner surfaces of pores due to the absence of grain boundary oxidation and carburizing unevenness in the surface layer ■ Finishes with a bright luster ■ Quality improvement can be expected compared to conventional carburizing hardening ■ JIS processing symbol: HQV *For more details, please refer to the PDF materials or feel free to contact us.

Adopting a processing method with minimal distortion! 【Deoxidation treatment・Carburizing quenching】

Adopting a processing method with minimal distortion! 【Deoxidation treatment・Carburizing quenching】

We are adopting the salt martensite quenching method and sub-zero treatment as processing methods with minimal distortion that can also be applied to thin plates and blades!

【Salt Marking Method】 Our pit-type carburizing atmosphere furnace and case-type carburizing atmosphere furnace are batch-type, allowing us to accommodate small quantities of diverse hardening processes. We offer a wide range of treatments, including deoxidation processing, carburizing hardening, as well as annealing and tempering. If you are facing difficulties with short delivery times due to differences in specifications such as steel types, carburizing depth, and base material hardness, please feel free to consult us. 【Sub-Zero Treatment】 Also known as deep cooling treatment, this process involves cooling below 0 degrees to transform residual austenite into martensite. The benefits of sub-zero treatment include (1) increased hardness, (2) prevention of distortion, and (3) improved wear resistance. It is an ideal treatment for enhancing the high added value of molds and cutting tools. *For more details, please download the materials or contact us.*

High surface pressure resistance technology "KHD treatment"

High surface pressure resistance technology "KHD treatment"

Vacuum hardening that improves the durability of molds and tools by more than three times! Introduction of our uniquely developed technology.

We would like to introduce KHD processing, a unique development technology by Kuniyu Thermal Engineering. From the perspectives of weight reduction for improved fuel efficiency and enhanced safety, the introduction of high-strength steel materials is increasing. However, these materials are difficult to process, leading to significant wear on molds and tools, which necessitates improvements in strength and durability. Our development technology applies vacuum carburizing treatment to these tools, achieving excellent surface modification treatment for high surface pressure wear resistance, thereby extending the "lifespan" of molds and tools. This results in cost reduction through decreased frequency of mold replacements and improved productivity, while also addressing the anticipated "further adaptation to higher strength steel materials" in the future. [Key Points] ■ Hard coating with high resistance to high surface pressure → Generates a hard coating on the surface of the component with a hardness of approximately Hv3,000 (Hv = Vickers hardness) - Result: Wear resistance to high surface pressure is enhanced by more than twice ■ High adhesion "non-peeling coating" → Creates a "substrate gradient reinforcement layer" with a gradient hardness distribution into the base material - Result: Achieves three times the adhesion of conventional coatings with a "non-peeling coating" *For more details, please refer to the PDF document or feel free to contact us.

Features of gas carburizing

Features of gas carburizing

"Gas carburizing nitriding hardening" allows for low-temperature treatment at around 800°C! Introducing the features of gas carburizing.

"Gas carburizing" is a treatment that involves infiltrating and diffusing carbon into the surface of steel in a high-temperature gas primarily composed of hydrocarbon gas, followed by rapid cooling to form a hardened surface layer. It is mainly performed to improve the wear resistance and fatigue strength of components. Our company offers "gas carburizing hardening" and "gas carburizing nitriding hardening," accommodating a wide range from micro parts such as precision components for machining tools to large items like shield cutters for shield tunneling and gear reducers for heavy machinery and industrial machines, including both shallow and deep carburizing of alloy steel and carbon steel. [Features] ■ Gas carburizing hardening - Improved surface hardness - Enhanced toughness in the core - Increased strength and wear resistance *For more details, please refer to the PDF materials or feel free to contact us.
