Alloy Steel Sheet 4130 Annealed

The main reason to anneal 4130 steel is to prepare it for machining.

Alloy steel sheet 4130 annealed. It will be transferred from the forge into a furnace and kept at a temperature of approximately 860 c. Relatively high carbon high alloy steels like american iron and steel institute aisi 4130 must be heat treated before they can be machined or formed. Once 4130 steel has been forged into parts sheets or coils it may be annealed straightaway. Due to its relatively low carbon content of 0 28 0 33.

This type of steel is also commonly referred to as a chromoly steel or chrome moly steel. Two processes change the hardness of 4130 annealing and normalizing both of which may be applied depending on the desired application of the steel. 4130 annealed sheet produced to the aerospace specification ams 6350 sometimes referred to as condition a. The 4130 alloy steel grade contains chromium and molybdenum for strength and hardenability with lower carbon content than 4140 alloy steel to provide better weldability.

4130 steel sheets mil s 6345a normalized formerly mil s 18729c this chromium molybdenum alloy is one of the most widely used aircraft steels because of its combination of weldability ease of fabrication and mild hardenability. It s often used for structural applications. Annealing relieves internal stresses softens and makes the material more ductile. 4130 alloy steel has a low carbon content that provides good weldability.

4130 steel sheet plate stock is available in full size and custom cut lengths. Alloy steel sheet plate 4130 is highly versatile and used for a wide range of applications including automotive aerospace bicyling construction and firearm projects. The 4130 alloy steel sheet has been annealed has an unpolished mill surface meets sae aerospace material specifications ams 6350 standards and has a standard tolerance. It will be held there for a set amount of time then furnace cooled.

Aircraft quality 4130 alloy steel is a medium carbon low alloy steel containing 0 15 0 25 molybdenum and 0 80 1 10 chromium as strengthening agents. The annealed condition is the softer and formable condition and is best used when forming is needed. Alloy steel sheet 4130 annealed offers good strength and weldability without compromising steel abrasion or impact resistance. 4130 steel offers good strength weldability impact and abrasion resistance while also being easy to machine.
