Carbon Steel Saw Blade

A carbon steel saw blade is a cutting tool primarily used for sawing various materials, notably wood, metal, and plastics. Its defining characteristic is its composition – it is manufactured from carbon steel, an alloy of iron and carbon.

Material

Carbon steel used in saw blades typically contains between 0.3% and 1.5% carbon. The carbon content directly influences the blade's hardness and flexibility. Higher carbon content leads to greater hardness but reduced ductility, making the blade more brittle. Common types of carbon steel used include:

• High Carbon Steel (HCS): Offers good hardness and wear resistance, suitable for general-purpose cutting.
• Tool Steel (e.g., SK5, D2): Higher alloy content provides improved heat treatment capabilities, resulting in blades with superior durability and edge retention.

Purpose

The primary purpose of a carbon steel saw blade is to efficiently and accurately cut through materials. They are versatile tools used in a wide range of applications, from DIY projects to professional construction and manufacturing.

Function

The blade functions through a reciprocating or rotating motion, where the sharp teeth remove material in the form of chips. The teeth are designed with specific geometries – tooth shape, pitch (distance between teeth), and set (angle of teeth) – optimized for particular materials and cutting tasks.

Usage Scenarios

• Woodworking: Cutting lumber, plywood, and other wood-based materials.
• Metalworking: Cutting pipes, rods, sheets, and other metal components.
• Plastics Cutting: Cutting acrylic, PVC, and other plastic materials.
• Hand Saws: Used in various hand saw types like hacksaws, coping saws, and backsaws.
• Power Tools: Employed in reciprocating saws, band saws, circular saws, and jigsaw.

Common Types

• Hacksaw Blades: Designed for cutting metal, typically with a fine tooth pitch. Available in various lengths and tooth counts (TPI - teeth per inch).
• Wood Saw Blades: Feature coarser teeth optimized for removing wood material.
• Band Saw Blades: Continuous loops of steel used in band saws for contour cutting and resawing.
• Jigsaw Blades: Narrow, reciprocating blades for intricate cuts in wood, metal, and plastic.
• Circular Saw Blades: Rotating blades used for straight cuts in wood and other materials.
• Bi-Metal Blades: Combine a high-speed steel tooth strip with a flexible carbon steel body, offering increased durability and resistance to breakage. (While not purely carbon steel, they often incorporate it as a backing material).

Carbon steel saw blades fall under several potential classifications based on their specific characteristics and application. Here's a breakdown of relevant HS codes based on the provided information:

• 8202913000: This code covers handsaws and metal parts thereof; blades for saws of all kinds (including slitting, slotting or toothless saw blades), and base metal parts thereof: Other saw blades, and parts thereof: Straight saw blades, for working metal: Hacksaw blades. If the carbon steel saw blade is a hacksaw blade designed for metalworking, this is a primary classification. The first two digits (82) indicate tools, the next two (02) specify handsaws, and the subsequent digits further refine the classification to metal-working straight blades like hacksaw blades.
• 8202990000: This code encompasses handsaws and metal parts thereof; blades for saws of all kinds (including slitting, slotting or toothless saw blades), and base metal parts thereof: Other saw blades, and parts thereof: Other (including parts). If the carbon steel saw blade doesn't specifically fit the 'hacksaw blade' description but is still a saw blade for metalworking, this is a suitable classification.
• 7213914500: This code covers bars and rods, hot-rolled, in irregularly wound coils, of iron or nonalloy steel: Other: Of circular cross section measuring less than 14 mm in diameter: Other: Containing by weight 0.6 percent or more of carbon. If the carbon steel saw blade is supplied as a hot-rolled bar or rod containing 0.6% or more carbon, this code may apply.
• 7228308015: This code covers other bars and rods, not further worked than hot-rolled, hot-drawn or extruded: Other With a diameter or cross section measuring less than 76 mm. If the carbon steel saw blade is supplied as a bar or rod that has not undergone significant further processing beyond hot rolling, hot drawing, or extrusion, and its diameter or cross-section is less than 76 mm, this code may be applicable.
• 7228800000: This code covers other bars and rods of other alloy steel; angles, shapes and sections, of other alloy steel; hollow drill bars and rods, of alloy or nonalloy steel: Hollow drill bars and rods. If the carbon steel saw blade is a hollow drill bar or rod, this code applies.

Important Considerations:

Regarding HS codes 7213914500 and 7228308015, please note that these codes apply specifically to the raw material form of the carbon steel (i.e., as a bar or rod). If the material has been processed into a finished blade, codes 8202913000 or 8202990000 are more appropriate.

According to the provided reference material, the HS code options related to 'carbon steel saw blade' are limited, with only the following 5 found.
