Some common applications for 4130 steel include tubing, sheet metal, structural shapes and automotive parts. 4130 can be easily welded, machined or formed without causing damage to the 4130 steel. 4130 is great for applications where a high strength to weight ratio and corrosion resistance are required such as in automotive parts including exhaust tubing and headers. 4130 can also be used in structural shapes because of its ability to withstand wear and tear from weathering or other types of corrosion. 4130 is not as tough as 4340, so it should not be used in applications that require a high amount of toughness.
