0.188″ 17-4 Stainless Round Rod, 36″ (10 Pack)

The 17-4 Cond A stainless steel round rod offers strong corrosion resistance and good strength, making it a versatile choice for precision fixtures and knife components. With a 36-inch length and a 0.188-inch diameter, these bars are suitable for turning, drilling, and grinding operations. The precision-ground finish helps reduce tool wear and improve surface finish on machined parts. Ideal for projects requiring a reliable stainless steel base for high-stress environments.
Key considerations:
– Material: 17-4 PH stainless steel, precipitation-hardening alloy.
– Finish: Precision ground for tight tolerances.
– Applications: Knife handles, brackets, precision fittings, and small-diameter shafts.
– Machinability: Good, with heat treatment options for enhanced hardness.
– Availability: Sold in multiple-pack configurations to suit batch needs.
0.188″ 3 Pack 17-4 Stainless Round Rod, 36″ Length

This option delivers three 36-inch rails of precision-ground 17-4 stainless steel, suitable for longer components and repeatable runs in a shop setting. The smaller pack size is convenient for hobbyists or project-based work without sacrificing corrosion resistance or strength. Precision grinding aids in achieving smoother transitions and tighter tolerances when shaping and finishing parts.
Key considerations:
– Pack size: 3 rods in a single package.
– Material performance: 17-4 Cond A stainless steel with good hardness after heat treatment.
– Ideal use: Prototyping, fixtures, and long components requiring precise diameter control.
– Surface quality: Optimized by precision grinding to reduce post-processing time.
0.188″ x 36″ 17-4 Cond A Stainless Steel Round Rod

This single 36-inch stainless steel rod provides a straightforward option for projects demanding a continuous length with high strength and corrosion resistance. Precision ground finishes improve alignment and reduce the need for aggressive machining later in production. This size is well-suited for custom bars, pins, or shaft-like components where precise diameter and surface quality matter.
Key considerations:
– Length: 36 inches, single piece.
– Material: 17-4 Cond A stainless steel for robust mechanical properties.
– Machining: Durable and easy to work with using standard tooling.
– Applications: Custom shafts, hinges, and precision fixtures needing reliable stainless support.
5 Pack 1095 Steel for Knife Making

1095 high-carbon steel is a favored choice for knife making due to its toughness and edge retention after grinding. Annealed and precision ground, these flat stock bars provide a reliable base for shaping keen blades. Each package includes five blanks at 12″ x 1.5″ x 0.12″, offering ample material for multiple projects. The combination of cold-rolled processing and annealing improves machinability and reduces edge cracking during the grinding process.
Key considerations:
– Carbon content: Approximately 0.95–1.0%, enabling strong hardness after heat treatment.
– Processing: Cold-rolled and annealed for easier machining and grinding.
– Package: Five blanks per pack for multiple blade projects.
– Suitable uses: DIY knives, hobby blades, and tool handles requiring strong steel with good grindability.
1 Pack 1095 High Carbon Tool Steel Blanks

This single-pack option focuses on knife maker flexibility, providing a precise 12″ x 1.5″ x 0.12″ blank suitable for crafting durable blades and tools. The 1095 alloy is well-suited for applications requiring strong edge retention and responsive grindability. Annealed during processing to facilitate machining, it offers predictable performance for hobbyists and professional makers alike.
Key considerations:
– Quantity: 1 blank per package for individual projects.
– Material properties: 1095 high-carbon steel with excellent hardness after treatment.

ETD 150 alloy steel provides a balanced combination of strength, toughness, and machinability. The 0.937″ diameter and 24″ length format is suitable for longer shafts, spacers, or machining projects that require a robust cylindrical stock. This grade is often used for general-purpose structural components, fixtures, or turned parts where endurance under stress is important. Grinding characteristics support clean finishes with reduced tool wear.
Key considerations:
– Material class: ETD 150 alloy steel.
– Size: 0.937″ diameter, 24″ length.
– Applications: Turned parts, shafts, fixtures, and structural components.

Buying Guide: Key Considerations for Precision Ground Bar Stock
- Material selection: Stainless steels (like 17-4) offer corrosion resistance and strength, while high-carbon tool steels (like 1095) provide edge retention and hardness after heat treatment. O1 and ETD 150 alloys add toughness and broader machinability for diverse projects.
- Ground finish and tolerances: Precision-ground stock reduces surface roughness, improves fit in assemblies, and lowers post-processing time. Confirm grind quality, straightness, and diameter tolerances before purchase.
- Length and quantity: Choose packs that align with project scale. Longer lengths minimize joins, while multi-pack options support batch production or future projects.
- Machinability and heat treatment: Annealed blanks grind and cut more easily; heat-treatment capabilities determine achievable hardness. For blades, consider materials that respond well to quenching and tempering.
- Applications: Identify whether your project requires corrosion resistance, edge retention, or high toughness. 17-4 stainless suits environments with moisture exposure; 1095 and O1 are common in knife making and tooling.
- Availability and sourcing: Availability in various pack sizes helps manage inventory for hobbyists and professionals. Reliable vendors with consistent stock reduce project delays.
- Safety and handling: When working with metal stock, use proper PPE, secure materials during machining, and follow appropriate heat-treatment and grinding safety protocols.
- Cost considerations: While prices aren’t listed here, compare price-per-foot or price-per-piece across pack sizes. Factor in material properties and expected tool wear when evaluating value.
