- Q: Many gerber knives are made out of what gerber calls high Carbon steels and I was wondering if anyone knew exactly what is this mysterious steel.
- A steel knifeblade is like a box full of a million ball bearings. The molecules pile up/line up just like those ball bearings. When it's pure, though, you can easily deform it....just like you can ram your hand down into that box of ball bearings. What happens if you pour a gallon of heated wax over those bearings, though? It fills the gaps between the molecules and solidifies the entire mass into one solid shape. If you smack it then, you'll break your hand. It'll hold its shape *much* better and longer. That's pretty basic but what do you expect at 04:00? ;) Addendum: At one time, in the late 80's to mid 90's, it was 440a...they then switched to 440c on their mass market stuff and 154 on their special runs....late 90's-2005 went to all 440c....today's knives are a mix of 440c and some pricier knives sporting S30V blades. If it's Gerber and it costs less than $40 today, 99% of the time it will be 440c.
- Q: What are the different methods of slitting steel coils?
- There are several different methods of slitting steel coils, each with its own advantages and limitations. Some of the most common methods include: 1. Rotary Shear Slitting: This method involves using rotating knives to cut the steel coil into narrower strips. It is a versatile and efficient method that allows for high-speed production and precise slitting. Rotary shear slitting is commonly used for thinner gauge materials. 2. Looping Pit Slitting: In this method, the steel coil passes through a looping pit where it is guided and tensioned before being slit. It is suitable for thicker gauge materials and provides good edge quality. Looping pit slitting allows for higher coil speeds and can handle heavier coils. 3. Drag Slitting: This method involves dragging the steel coil over a stationary blade or set of blades to perform the slitting. It is particularly useful for materials that are difficult to slit, such as high-strength steels. Drag slitting provides excellent edge quality and is often used for precision slitting applications. 4. Crush Slitting: Crush slitting involves applying pressure to the steel coil to crush and separate it into narrower strips. It is a cost-effective method suitable for lower gauge materials. However, it may result in slightly rougher edge quality compared to other methods. 5. Laser Slitting: Laser slitting utilizes a focused laser beam to cut through the steel coil. It is a highly precise method that offers excellent edge quality and minimal distortion. Laser slitting is commonly used for high-value and specialty materials. Each method has its own advantages and is suitable for specific applications and material types. The choice of slitting method depends on factors such as material thickness, desired edge quality, production speed requirements, and budget.
- Q: What are the different methods of testing steel coils for quality control?
- Steel coils undergo various methods for quality control testing to ensure they meet the necessary specifications and standards. These methods encompass visual inspection, dimensional measurement, hardness testing, tensile strength testing, chemical analysis, coating thickness measurement, surface roughness measurement, ultrasonic testing, and magnetic particle inspection. Visual inspection is the most fundamental technique, involving a thorough examination of the coils for surface defects like scratches, dents, or irregularities. This method enables the identification of visible defects in the material. Dimensional measurement, on the other hand, utilizes tools such as calipers, micrometers, or laser measuring devices to evaluate the dimensions of the steel coils. The measurements are compared against specified tolerances to ensure they meet the required standards. To assess the resistance of the steel coils to indentation or penetration, hardness testing is performed. This examination helps evaluate the material's strength and durability. Common hardness testing methods include Rockwell, Brinell, and Vickers hardness tests. Tensile strength testing measures the maximum tensile stress a steel coil can endure before breaking or deforming. This test helps determine the material's strength, elasticity, and compliance with the required specifications. Chemical analysis is crucial in testing the composition of the steel coils to verify the presence of specific elements in the desired amounts. This ensures that the coils are made from the correct grade of steel and comply with the required chemical composition standards. In cases where the steel coils have a protective coating, it is vital to measure the thickness of the coating. Non-destructive testing methods like magnetic induction or eddy current testing are typically employed for this purpose. The coating thickness is compared against the specified requirements to ensure it provides adequate protection. Surface roughness testing evaluates the smoothness or roughness of the steel coil's surface using instruments like profilometers or roughness testers. This testing method guarantees that the coils meet the required surface finish standards. Ultrasonic testing utilizes high-frequency sound waves to detect internal defects like cracks, voids, or inclusions within the steel coils. This non-destructive testing method provides valuable information about the structural integrity of the coil. Magnetic particle inspection is employed to identify surface and near-surface defects in steel coils. By applying magnetic particles to the surface and detecting any magnetic leakage caused by defects using magnetic sensors, this technique effectively detects cracks and other surface abnormalities. By combining these testing methods, manufacturers ensure that the steel coils produced meet the necessary quality standards and are suitable for their intended applications.
