Corrosion-Resistant High-Strength 1045 Carbon Steel
- Yield Strength: 75,000 psi
- Hardness: Rockwell C65 (Very Hard)
- Heat Treatable: No
- Specifications Met: ASTM A108
This steel is nitrided, which involves the absorption of nitrogen, providing a corrosion-resistant surface that won’t flake or chip. It is comparable to NitroSteel. 1045 carbon steel is stronger than low-carbon steel but just as machinable. This steel is often used for applications subject to wear and friction such as gears, shafts, and bushings. All of these rods meet ASTM A108 standards for strength, machinability, dimensions, and material.

Hardened High-Speed M2 Tool Steel Sheets
- Yield Strength: 65,000 psi
- Hardness: Rockwell C65 (Very Hard)
- Specifications Met: ASTM A600
Hardened for increased abrasion and impact resistance, these sheets are also known as flat stock. A nice balance of wear resistance and machinability make M2 tool steel suitable for most high-speed cutting tools. It has a high molybdenum content, which allows it to maintain a sharp cutting edge even at elevated temperatures.
