4130 vs 5140
4130 vs 5140 : what is the difference between 4130 steel and 5140 steel?
A： Today we will discuss 4130 steel and 5140 steel.
B： Distinguish from the type of steel, 4130 steel and 5140 steel are all alloy steels.
A： From the analysis of their content, their carbon content is 0.38%-0.43%
B： And the chromium content of 4130 steel is 0.80%-1.10%, while the chromium content of 5140 steel is 0.7%-0.9%.
A：4130 steel can be used for structural tubing, bicycle frames, gas bottles for transportation of pressurized gases, firearm parts, clutch and flywheel components, and roll cages.
B：5140 steel can be used for low and moderately stressed parts for vehicles, engines, and machines where a hard, wear-resistant surface is needed. Its hardness as surface hardened about 54 HRC. 5140 sheets of steel can also be for the marine engineering industry, chemical processing plants, boiler & pressure vessels, nuclear power plants, etc.
A： So what is the difference between them?
B：4130 steel has an excellent strength to weight ratio but is not easily welded, requiring thermal treatment both before and after welding to avoid cold cracking.
A：I hope that customers should consider what kind of performance you need for the steel that you purchase and then buy on demand.
B： By the way, for 4140 steel, we can supply the round bar, steel flat bar, and plate.
A： Rectangular pieces can be cut from flat bar or plate to your specific sizes.
