4130 Stainless Steel Hardness

Astm 4140 steel is also commonly referred to as a chromoly steel or chrome moly steel containing nominally 0 28 0 33 carbon 0 8 1 1 chromium and 0 15 0 25 molybdenum.

4130 stainless steel hardness. Some of the major applications of aisi 4130 alloy steel are in aircraft engine mounts and welded tubing. Download certificates from activity after your order ships. The hardenability and weldability of alloy 4130 are considered equivalent to 8630 mil s 6250. Aisi 4130 alloy steel west yorkshire steel.

Tw s cold drawn seamless 4130 alloy steel bar rod and wire is a lighter weight higher strength alternative to carbon steel. Certificates with a traceable lot number are available for these products. What is 4130 steel. Type 4130 steel has a rockwell hardness of 92 which is high for steel and shows why this material is so tough.

It is similar to 4140 steel which has a higher carbon level. A high hardness usually indicates increased stiffness which is an ideal property for materials in compression. It s often used for gears fasteners and structural applications. Tempering of aisi 4130 steel can be performed at 399 to 566 c 750 to 1050 f depending on the desired strength level.

Hardening of aisi 4130 steel can be done with cold working or heat treatment. Aisi 4130 alloy steel is a medium carbon low alloy steel in astm a29 standard. Aisi 4130 is a chromium molybdenum alloy steel specification. Material 4130 alloy steel forging temperature is about 1204 c 2200 f welding 4130 steel.

Tempering temperature of 4130 alloy steel can be from 204 649 c 400 1200 f after normalizing and water quenching and the corresponding rockwell hardness can be obtained. Alloy 4130 is also vacuum degassed to meet the magnetic particle inspection standards of ams 2301. Alloy 4130 is a widely used aircraft steel due to its weldability ease of fabrication and mild hardenability.
