4130 Stainless Steel

4140 steel is also commonly referred to as a chromoly steel or chrome moly steel.

4130 stainless steel. Its great heat treatment characteristics impart a high toughness and combined with its great workability and machinability allows 4130 steel to be widely useful. Bars sheets tubing. These rods have been normalized for consistent hardening and machining. Chromoly 4130 is a low alloy steel containing chromium molybdenum iron carbon and other alloying elements.

The steel has a carbon content between 0 28 and 0 33 percent a chromium content between 0 8 and 1 1 percent manganese content between 0 7 and 0 9 percent molybdenum between 0 15 and 0 25 percent and a silicon content between 0 15 and 0 35 percent. The addition of chromium to steel improves strength and corrosion resistance and the molybdenum increases material toughness. Stainless steel brass in. 4150 stands out as being one of the steels accepted for use in m16 rifle and m4 carbine barrels by the united states military.

Aisi 4130 steel is a medium carbon low alloy steel in astm a29 standard. Aisi 4130 steel uns g41300 also known as 4130 chromoly steel is a chrome molybdenum series low alloy steel with high strength toughness and hardenability usually used in quenched and tempered condition. 4130 steel sheet is considerably stronger and harder than other standard steel grades and is commonly used in construction of commercial and military aircraft. Sheets plates in 4130 condition a n.

4130 alloy steel has a low carbon content for good weldability. The hardenability and weldability of alloy 4130 are considered equivalent to 8630 mil s 6250. 4130 round in condition 4. Examples of applications for 4130 4140 and 4145 include structural tubing bicycle frames gas bottles for transportation of pressurized gases firearm parts clutch and flywheel components and roll cages.

Alloy 4130 is a widely used aircraft steel due to its weldability ease of fabrication and mild hardenability. It s often used for gears fasteners and structural applications. While these grades of steel do contain chromium it is not in great enough quantities to provide the corrosion resistance found in stainless steel. Aisi 4130 steel has a specialized chemical composition that gives it a unique set of properties.

4130 chromoly tubing also has a smooth interior and exterior finish that resists scaling and oxidation. Alloy tubing in 4130 4140 4340. 4130 sheet is readily machinable has excellent weldability and offers excellent ductility. 4130 steel 4130 aircraft steel 4130 alloy tubing 4130 steel tubing 4130 steel sheets detroit michigan steel aluminum supplier.
