UNS NO. G50461 is a low-chromium alloy steel with boron added to increase its hardenability. This steel has medium hardenability and strength with good ductility. It is used in a wide range of machinery and tool applications where its properties meet the requirements. Another grade (UNS No. H50461) has similar properties but slightly wider ranges in percentages of carbon, manganese and chromium; this is known as the H-grade (Hardenability grade). This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SA-408. Producer or source: Alloy steel mills and foundries.
