440C Barstock for Knife Making — 1/8″ x 1-1/4″ x 12″
This premium martensitic 440C stainless steel barstock is designed for knife blades. It contains approximately 17% chromium for corrosion resistance and a carbon level around 1.1%, contributing to hardness and wear resistance. Dimensions are 1/8″ by 1-1/4″ by 12″, making it suitable for small to medium blades and blade blanks. Best for: dedicated knife makers who want a consistent barstock ready for grinding and heat treatment. Limitation: small cross-section may require meticulous grinding to reach final geometry.
WOODRIVER Drop Point Skinner Knife Kit With Black Leather Sheath
This knife kit uses 440C stainless steel for the blade and includes a fitted black leather sheath. It’s a solid option for beginners or hobbyists seeking a complete project with assemble-ready components. Best for: new or hobby knife makers who prefer a guided build and a durable, general-purpose blade. Caution: the kit’s overall performance rests on proper assembly and sharpening; verify tolerances before fitting scales.
440C Stainless Steel Round Bar, 0.4375″ Diameter, 36″ Length
This 0.4375″ diameter round bar comes in a 36″ length, offering good strength, moderate corrosion resistance, and wear resistance. It’s commonly used in knife blades, surgical instruments, molds and dies, and other precision components. Best for: shops needing longer stock for multiple blades or tooling. Limitation: standard mill finish means additional finishing may be required for certain applications.
440C Stainless Steel Round Bar, 0.875″ Diameter, 12″ Length
This 0.875″ diameter bar of 440C stainless steel in a 12″ length provides a sturdy option for mid-size blades or chisels. Best for: makers needing a thicker stock for robust blades or tools. Caution: larger diameter requires more substantial tooling and grinding effort during fabrication.
440C Stainless Steel Round Bar, 1″ Diameter, 72″ Length
The 1″ diameter, 72″ length stock provides a long run of material for blade blanks or other large components requiring substantial cross-section. Best for: professional shops or makers planning multiple blades or large-format tools. Limitation: heavy material requires strong machinery and extra grinding effort.
440C Stainless Steel Round Bar, 0.4375″ Diameter, 12″ Length
This 0.4375″ diameter, 12″ length bar offers compact sizing for small blades or tool components. Best for: hobbyists testing 440C performance on a budget. Caution: shorter stock limits the number of blades you can produce from a single piece.
440C Stainless Steel Round Bar, 0.4375″ Diameter, 24″ Length
This 24″ length option is ideal for small runs of blade blanks or prototype blades. Best for: shops needing a mid-length stock without committing to full mill stocks. Limitation: available stock may require cutting or trimming to fit specific project dimensions.
Buying Guide: Key Considerations For 440C Stainless Steel Purchases
Material purpose: Choose barstock for blade blanks or long-term tooling that benefits from wear resistance and sharpness. Knife kits are ideal for beginners who want a guided build with a durable blade.
Diameter or thickness: Match stock size to your blade geometry, grinding equipment, and target applications. Smaller diameters are easier to shape; larger diameters offer more rigidity for heavy-duty tools.
Length: Longer lengths reduce the need for frequent reorders in production runs; shorter lengths suit small projects or experimentation.
Finish and treatment: Mill finishes may require additional finishing; consider heat treatment and tempering requirements for 440C to achieve optimal hardness and edge retention.
Machinability and tooling: 440C can be tougher to machine than some stainless steels. Ensure your tooling and setup can handle the material without excessive wear or heat buildup.
Corrosion resistance: While 440C offers good corrosion resistance, proper care and maintenance extend blade life, especially for outdoor or high-humidity environments.
Cost and availability: Availability varies by supplier, so compare lead times and stock consistency when planning larger projects or repeat orders.
FAQ
- What is 440C stainless steel used for in knifemaking? 440C is a martensitic stainless steel known for hardness, wear resistance, and decent corrosion resistance, making it popular for blade blanks and knife components.
- Is a mill finish acceptable for blades? A mill finish is common, but many makers finish blades further to improve performance and corrosion resistance.
- Which diameter stock is best for a beginner knife blade? A smaller diameter stock (e.g., 0.4375″) is easier to handle and shape for beginners, while larger stocks suit more robust designs.
- Do all 440C products require heat treatment? Yes, 440C typically undergoes heat treatment to maximize hardness and edge retention, though specific processes depend on the final blade design.
- Can I use 440C for surgical instruments? 440C’s combination of hardness and corrosion resistance makes it suitable for some surgical-grade components, but consistency with medical-grade standards should be verified for each use.
- What should I consider when buying 440C from Online Metals? Check dimensions, length, and finish, and confirm compatibility with your machining processes and intended blade design.
