4130 Alloy Steel
Qilu is an 4130 alloy steel manufacturer that offers a wide selection of sizes, shapes, and thicknesses.
Professional 4130 Alloy Steel Supplier
4130 alloy steel is a low legierter Stahl, it is widely used for its excellent mechanical properties and cost effectiveness. It has about .0.15% carbon and 1% chromium, and it has slight other other alloy elements such as manganese, silicon, molybdenum and phosphorus. This steel’s grade follows the SAE standard in the United States. The “41” shows that it is chromium molybdenum alloy steel series.And “30” shows that its average carbon content is about 0.30%.
