Key Properties
EN-24 (4340)
Nickel Chromium Molybdenum SteelThe ultimate high-tensile steel. EN-24 contains Nickel (1.5%), Chromium, and Molybdenum, giving it deep hardenability. It retains its toughness even in large cross-sections where other steels might become brittle at the core.

Key Properties
EN-31 (52100)
High Carbon Bearing SteelA high-carbon, high-chromium steel designed for extreme surface hardness and compressive strength. Commonly known as "Bearing Steel". It takes a mirror polish and is extremely resistant to wear.

Key Properties
EN-19 (4140)
Chromium Molybdenum SteelThe workhorse of the alloy steel world. EN-19 offers a good balance of ductility and shock resistance. Suitable for components that require higher strength than carbon steel but don't need the expense of Nickel alloys.

Key Properties
EN-8D / EN-9
Medium Carbon SteelsHigh-quality carbon steels for general engineering. EN-8D is ideal for shafts that need induction hardening. EN-9 has higher carbon for better wear resistance in cams and rollers.

Key Properties
SS-410
Martensitic Stainless SteelA hardenable stainless steel. Unlike SS-304, this grade is magnetic and can be heat treated for high strength and moderate corrosion resistance. Perfect for pump shafts and valves.
