4140 (42CrMo4 / SCM440 / EN19)
AISI 4140 steel is a low alloy blend containing chromium, molybdenum, and manganese. It’s highly favored across various industries for its impressive toughness and resistance to wear. Additionally, it’s known for its ability to withstand impacts well. Truly, few types of steel match the versatility and usefulness of 4140.
4340 (34CrNiMo6 / EN24)
SAE 4340 steel is a medium carbon, low alloy steel known for its toughness and strength, especially in large sections. It contains a blend of nickel, chromium, and molybdenum. Usually, it’s hardened and tempered, with a strength range of 930 – 1080 Mpa.
5140 (41Cr4)
5140 steel is a type of structural alloy steel. It’s really important for parts that have low to moderate stress, such as in vehicles, engines, and machines. It’s great for situations where you need a surface that’s tough and can resist wear.
8620 (1.6523)
AISI 8620 Steel is a low alloy combination containing nickel, chromium, and molybdenum. It’s really good for case hardening. Typically, it’s produced with a hardness level that stays below HB 255.
18CrNiMo7-6 (1.6587)
DIN 1.6587 steel is a case-hardening alloy that’s really popular for making super hard surfaces. Its special chemical composition makes it not only long-lasting but also really good at resisting daily wear and tear.
30CrNiMo8 (1.6580)
DIN 30CrNiMo8 material is a type of structural steel known for its good hardenability, making it ideal for heavy-duty applications. Its key features are its excellent resilience and strength.
