Alloy Steel Fasteners

Alloy steel improves upon carbon steel in virtually every way:

• High tensile strength (~960 MPa)
• Excellent toughness, impact resistance, and vibration resistance
• Outstanding ductility
• Strong hardness, wear resistance, and scratch resistance
• Good conductivity and temperature resistance (can be heat treated)
• High resistance to corrosives and oxidation

One downside of alloy steel is the higher cost of materials. Also, alloy steels aren’t as easy to weld as low-carbon steel.

In general, alloy steel is more difficult to machine, and strict processes are necessary to meet OEM specifications precisely. Valley Fastener Group has over 40 years of experience and an excellent reputation with industry-leading manufacturers.

By cold-forming alloy steel screws and fastener heads, we can deliver maximum performance. The cold-forming process provides dimensional accuracy, work hardening, enhanced strength, and well-defined contours for drive heads. Precision is especially critical for self-tapping fasteners, indented head styles, and all rivets.

Valley Fastener Group can manufacture nearly any type of alloy steel fastener required for manufacturing, construction, or industrial needs:

• Rivets: Self-piercing, collar, blind, solid, semi-tubular, and shoulder rivets
• Screws: SEMs, U-drive screws, machine screws, and thread-forming screws
• Fasteners: Washers, bolts, and self-clinching studs
• Heads: Truss, fillister, indented hex, pan, button, and specialized heads

Alloy steel fasteners can adapt perfectly to OEM products and structural specifications.

Alloy steel consists of iron, carbon (~0.15% to 0.2%), and small amounts of other materials, including manganese, nickel, chromium, molybdenum, phosphorus, and/or silicon. These different alloying materials are responsible for increasing corrosion resistance, thermal characteristics, and hardness as needed:

• Chromium: Hardness and corrosion resistance
• Molybdenum: Toughness and tensile strength
• Nickel: Resistance to heat, corrosion, and stress-corrosion cracking
• Silicon: Overall strength and magnetic characteristics

Customized alloy steel screws and rivets are common in tight-tolerance settings, such as aerospace and aviation. When each part has to meet repeatable characteristics, customized fasteners save time and reduce the risk of human error.

When choosing alloy steel fasteners, it’s critical to work with an expert manufacturer. Valley Fastener Group has the expertise and cutting-edge technology to deliver trustworthy results every time. Request a quote for more information.
