Alloy Steel Rectangle Bar, 18" L, 2 1/2" W
Our Alloy Steel Rectangle Bar is a versatile and reliable choice for a variety of applications. Made from grade 4142 alloy steel, this bar is heat treatable and exhibits a Brinell hardness of 187 and Rockwell hardness of 94 HRB. Its machinability of 50% makes it suitable for precision machining and fabrication. With a yield strength and tensile strength not rated, this bar is perfect for applications where high strength is not a primary concern. Use it in construction, manufacturing, or engineering projects, and take advantage of its durability and resistance to wear and tear.
Top product features:
- Hot Rolled fabrication provides a strong and durable base for the alloy steel.
- Pre-Hardened heat treatment allows for improved machinability and reduced risk of cracking.
- Mill finish provides a smooth surface for improved machining and reduced risk of tool wear.
