What Is SK5 Steel? Why Do We Use It to Make Snap-Off Blades?


When it comes to manufacturing high-quality blades, the choice of material is paramount. One material that has proven to be of exceptional quality is SK5 steel. But what exactly is SK5 steel? And why do we at Xirui Manufacturing choose it when producing our snap-off blades?

Understanding SK5 Steel

SK5 steel is a Japanese carbon steel that is known for its high toughness and hardness. It is named after the Japanese scale and its properties are similar to the American 1080 steel, which comprises approximately 0.80% carbon and up to 0.90% manganese 1.

This type of steel is designed to be very hard and durable, perfect for applications demanding high strength and resistance to wear. On the HRC scale, SK5 steel ranks at approximately 65, making it a very hard steel 2. Its alloy composition increases its strength and abrasion resistance.

The Advantages of SK5 Steel in Snap-Off Blades

At Xirui Manufacturing, we specialize in the production of various types of blades, including the 18mm Black SK5 Snap-Off Blade, which is highly appreciated in the market. Our decision to use SK5 steel in the manufacture of these blades was guided by several factors.

  1. Hardness and Durability: SK5 steel is very hard, which makes it perfect for a snap-off blade that needs to stay sharp even after repeated use. This hardness also means the blade is unlikely to break or crack under pressure, ensuring long-lasting performance.

  2. Sharpness: Despite its hardness, SK5 steel can be sharpened to a very fine edge. This quality is critical for any cutting tool, as it determines the ease and precision of the cut.

  3. Affordability: While SK5 steel offers exceptional performance, it is also relatively affordable compared to other types of steel. This affordability allows us to produce high-quality snap-off blades at a cost-effective price for our customers.

By using SK5 steel, we are able to bring together the critical elements of hardness, sharpness, and affordability in our snap-off blades. It’s the perfect choice for high-performance snap-off knives that professionals and hobbyists can rely on for their projects.

The Production Process of SK5 Steel Snap-Off Blades at Xirui Manufacturing

At Xirui Manufacturing, we pride ourselves in our production process that ensures each snap-off blade we make meets the highest quality standards.

The Making of SK5 Steel Snap-off Blades

The production of SK5 steel snap-off blades involves a series of steps:

  1. Alloying: The process begins with the creation of the steel alloy. SK5 steel is made from a blend of iron, carbon, and other elements such as chromium, nickel, and manganese. The precise blend and ratios depend on the desired properties of the steel.

  2. Forging: The alloy is then heated and forged into the shape of the blade. This is a critical step as it determines the blade’s final shape and size.

  3. Heat Treatment: After forging, the blade undergoes heat treatment. This process involves heating and cooling the blade to enhance its hardness, toughness, and tensile strength.

  4. Grinding and Polishing: The blade is then ground and polished to achieve a sharp edge and smooth finish.

  5. Quality Check: Each blade goes through a stringent quality check to ensure it meets our high standards. Only those that pass are approved for sale.
