1.4116/5Cr15Mov hot/cold rolled stainless steel

1.4116 (German standard grade ) is a high-carbon martensitic stainless steel, characterized by its dual advantages of corrosion resistance and high hardness. It is a comprehensive special-purpose material that combines wear resistance, corrosion resistance, and strength.

Applicable Scenarios:

Mid-to-high-end kitchen knives (mainstream)

Outdoor knives / multi-tools

Medical devices (some levels)

Food processing equipment

Everyday hardware knives

Advantages:

1️⃣ Corrosion Resistance 

• Cr Content: Approximately 14–15%

• Mo element enhances resistance to pitting corrosion

Performance:

• Strong rust resistance (suitable for kitchen/humid environments)

• Food-grade safe material

• Stable performance in marine/high humidity environments

2️⃣ Hardness (Controllable)

Standard hardness: 54–57 HRC After heat treatment, it can reach approximately 50–59 HRC.

Characteristics:

Not a high-hardness steel. More focused on "toughness + stability".

3️⃣ Sharpness (Easy to Sharpen)

• Fine microstructure → Easy to achieve a sharp edge

• Easy to sharpen and maintain

User Experience:

• Can achieve "razor-sharp" edge

• However, its sharpness retention is average, requiring regular sharpening.

4️⃣ Balanced Overall Performance 

The real advantage of 1.4116 lies in:

Corrosion resistance + toughness + ease of machining = the optimal balance for commercial applications

✔ Less prone to chipping

✔ Less prone to rusting

✔ Easy to control in mass production

Cleaning Surface:

Wash the surface with neutral soap and water applied with a cloth or a brush without scratching the stainless steel. Then, always rinse the stainless steel with water to remove completely the cleaning agent. Finally, it is recommended to dry the surface to preserve a good superficial condition. In severe environments, a frequent cleaning is strongly recommended.High quality hot sales products hot rolled 5Cr15Mov stainless steel sheet/plate.

Chemical Composition:

Performance:

Heat treatment of 5Cr15Mov stainless steel typically involves processes such as annealing, quenching, and tempering to achieve desired properties such as hardness, toughness, and corrosion resistance.

Here’s a general guide to the heat treatment process for 5Cr15Mov stainless steel:

1. Annealing:

• Heat the steel to around 800-900°C (1472-1652°F).

• Hold at temperature for a sufficient time to ensure thorough heating, typically 30 minutes per 25mm (1 inch) of thickness.

• Slowly cool in the furnace or in air to room temperature to relieve internal stresses and improve machinability.

2. Quenching:

• Preheat the steel to 950-1050°C (1742-1922°F) and then rapidly heat to the austenitizing temperature of around 1010-1070°C (1850-1958°F).

• Hold at temperature for 20-30 minutes per 25mm (1 inch) of thickness to ensure uniform temperature throughout.

• Quench in air, oil, or a suitable quenching medium (like a fast oil) to achieve martensitic transformation and high hardness.

3. Tempering:

• After quenching, immediately temper the steel to relieve internal stresses and improve toughness and ductility.

• Temper at a temperature range typically between 150-250°C (302-482°F) for 1-2 hours, depending on desired hardness and toughness.

• Higher tempering temperatures result in lower hardness but improved toughness, while lower tempering temperatures maintain higher hardness.

4. Additional Steps (if required):

• Cryogenic treatment: Some applications may benefit from a cryogenic treatment after tempering to further enhance hardness and dimensional stability.

• Surface treatments: Depending on the application, surface treatments like nitriding or coating may be applied to improve wear resistance or reduce friction.

5. Testing and Quality Control:

• Perform hardness testing (e.g., Rockwell hardness) to ensure the steel has reached the desired hardness level after heat treatment.

• Conduct microstructure analysis if needed to verify the effectiveness of the heat treatment process.

  
  

It's important to note that specific heat treatment parameters can vary based on the exact composition of the steel and intended application. Always refer to the manufacturer's recommendations or consult with a metallurgist for precise guidelines tailored to your specific requirements.
