Alloy Steel Rectangle Bar, 18" L, 1 1/2" W MPN:19176_18_0
Alloy Steel Rectangle Bar, 18" L, 1 1/2" W
This alloy steel rectangle bar is ideal for heavy-duty applications requiring high strength and durability. Made from 4142 alloy steel, it boasts a Brinell hardness of 187 and a Rockwell hardness of 94 HRB, ensuring it can withstand demanding conditions. With a yield strength and tensile strength not rated, this bar is suitable for applications where high stress is present. Its machinability of 50 percent makes it easy to work with, and its pre-hardened state allows for further heat treatment to achieve the desired level of hardness. Common uses include construction, manufacturing, and heavy machinery components.
Top product features:
- Hot Rolled fabrication provides a strong and durable base for the alloy steel rectangle bar.
- Pre-Hardened heat treatment enhances the bar's mechanical properties and resistance to wear.
- Mill finish provides a smooth surface for machining and reduces the risk of surface defects.
