High-Carbon Steel: The Value-for-Money Star
High-carbon steel saw blades are a favorite among DIY enthusiasts. Their carbon content of 0.6%-1.4% makes them hard and brittle, like a chocolate shell:
Advantages: Affordable price, high hardness, suitable for cutting soft materials such as wood and plastic.
Maintenance Tip: Allow the blade to cool down after every 20 minutes of use to prevent overheating and premature failure.
Alloy Steel: The All-Rounder
Alloy steel saw blades, containing elements like chromium and molybdenum, are like a fitness coach – strong and durable:
Enhanced Properties: Chromium provides rust resistance, and vanadium improves wear resistance.
Suitable Applications: Can handle medium-hardness materials such as metal pipes and hardwoods.
Identification Features: Often has a matte gray surface and weighs approximately 15% more than high-carbon steel.
High-Speed Steel: The Professional's Choice
High-speed steel saw blades, containing tungsten and cobalt, are the "special forces" of the cutting world, maintaining sharpness even at high temperatures:
Heat Resistance: Hardness does not decrease at temperatures up to 600°C.
Typical Applications: Continuous cutting of metals such as stainless steel and aluminum alloys.
Purchasing Tip: The blade tip shows the original metal color, and the price is usually 3-5 times that of ordinary saw blades.
