Zonon 2 Pcs Cold Rolled Round Bar
Diameter about 2.95 inches with a length of approximately 2.99 inches. This standardized size fits a variety of small-scale projects and crafts. Material is A36 cold rolled mild steel, chosen for corrosion resistance and durability. Best for: hobbyists and makers needing compact stock for crafts, fixtures, or prototyping. Caution: not ideal for high-strength structural applications due to its compact dimensions.
FOXCUP Steel Cold Rolled Round Bar
Diameter 5/8 inch, length 36 inches. Marketed with ASTM-A108 as a reference, indicating a standard for carbon steel bars. Best for: longer, continuous fabrication runs or shafts where consistent diameter is needed. Caution: verify exact chemical composition if you need specific alloy properties beyond the ASTM reference.
Rocaris 2pcs 1″ Diameter 1018 Bar
Two pieces of 1″ diameter, 12″ length. Made from 1018 carbon steel, offering good tensile strength and wear resistance. Cold rolled finish improves dimensional stability and surface smoothness. Best for: shafts, gears, and machine components where straightforward machining and reliable performance are needed. Limitation: for high-tensile or specialized alloys, verify if 1018 meets your exact strength requirements.
Metal Made Easy 1018 Steel Round Bar
One piece of 1″ diameter, 12″ length. 1018 carbon steel is noted for good workability and ease of forming. Best for: parts requiring cold forming, like crimping, swaging, or bending, as well as fixtures and mounting plates. Caution: may require stress-relieving for certain high-bend applications to prevent cracking.
1″ Diameter Round Bar, 1045 36″
1045 cold rolled steel, 1.00″ diameter, 36 inches long. Best for: longer, strong, machinable components and tooling stock. Caution: 1045 is a higher-carbon steel than 1018, which may require careful handling during machining to manage heat and wear.
Buying Guide: Key Considerations For Cold Rolled Round Bars
- Material type: Choose 1018 for easy machinability and good ductility; choose 1045 for higher hardness and strength; A36 is basic structural-grade steel with decent wear resistance.
- Diameter and length: Match stock dimensions to your project’s tolerance and finish requirements. Longer bars may need machining fixtures for stability.
- Finish and tolerances: Cold rolled stocks often have smoother surfaces and tighter tolerances than hot-rolled stock, aiding precision work.
- Application: For gears, shafts, or fixtures, select a material with appropriate strength and formability. For crafts or prototypes, ease of machining may be prioritized over ultimate strength.
- Corrosion considerations: If used outdoors or in humid environments, consider coatings or corrosion-resistant alloys or treat the surface.
- Availability and packaging: Value packs are useful for spares; individual pieces may simplify inventory management for specific tasks.
Frequently Asked Questions
- What is cold rolled steel used for? – It is used for parts requiring tight tolerances, smooth finishes, and decent strength in manufacturing and fabrication.
- Which material is easier to machine, 1018 or 1045? – 1018 generally machines more easily due to higher ductility, while 1045 offers greater strength but can be tougher to cut.
- Are these bars suitable for outdoor use? – Some bars are suitable with corrosion resistance, but consider protective coatings or indoor storage to extend life.
- What length should I choose for a shaft or fixture? – Choose a length that minimizes waste and allows for precise machining, with extra length for fixturing if needed.
- Do I need heat treatment after machining? – Most 1018 and 1045 stocks do not require heat treatment for standard fabrication, but complex parts may benefit from stress relief.
- Can I use these bars for gears or pulleys? – Yes, provided the diameter and material meet the required strength and tolerance for the gear teeth and load.
