As a popular option for cold work tool steel, the S7 variety possesses exceptional properties. This makes for different benefits. There is more than one reason why it is one of the most preferred cold work tool steel in various industries. This is how you can get help from this steel variety.

The Most Important Properties

The characteristics that make the S7 Cold Work tool Steel one of a kind are as follows:

• A high content of carbon: The S7 tool variety contains about 0.50% carbon. This makes it amazing wear resistance. Hardness increases too.
• High Chromium content: Good quality S7 cold work tool steel contains about 4% chromium. It helps improve toughness and corrosion resistance.
• High molybdenum content: The steel contains about 1.40% molybdenum. It not only improves the overall hardness of the metal but also gives superior resistance to shock and imparts maximum strength.

How do the properties benefit the tool?

As a variety of Cold Work Steel, S7 is more beneficial than many others because it offers:

• Unmatched wear resistance: It withstands adhesive wear and abrasion.
• Good high hardness: It helps to maintain optimal shape and also resists any type of metal deformation.
• Excellent thermal shock resistance: This makes it suitable to perform well even if there is a fluctuation in temperature.
• High level of toughness: This checks the chances of metal breaking and cracking.
• Fair resistance to corrosion: It gives due protection against corrosion and rusting.

How it helps in Cold Work Tooling

You can achieve maximum benefits from S7 tool steel due to:

• Longer tool life: The hardness of steel, as well as its wear resistance, helps expand its overall lifespan.
• More productivity: Since this steel variety requires minimal maintenance, they help expand the tool's life and thus extend its lifespan.
• More precision: The stable performance of the S7 tool steel ensures the most accurate tool performance.
• Lesser tool steel replacement: The high-quality tool steel reduces the need for tool replacement. This is how it also reduces the chances of frequent repair and replacement.

The most common Applications

Typically, S7 cold work tool steel is helpful in applications that involve:

• Cutting dies (such as scissors and knives).
• Punching and forming dies.
• Components that resist the impact of water, such as scissors and knives.
• Molds are helpful for different types of cold forming. These include sleeves and bushings.
• Machinery components that need high precision.

Comparison to Other Types of Steel

Steel tools like D2 and A2 might have many properties in common with them. Yet, they differ from each other in various aspects. For example:

• When comparing S7 with D2, you should know that the former has more toughness, but it is low in hardness. Again, D2 offers higher hardness, but it is relatively low in toughness, as well.
• When comparing S7 with A2, the former offers better wear resistance. But then again, it has low corrosion resistance. A2, on the contrary, offers more corrosion resistance but low wear resistance.

The Final Words

S7 steel is unique and offers excellent toughness to thermal shock. These properties make it a good choice for various cold work tooling applications. It is one of the bestselling products of premier steel supplies like Kushal Steel.
