Don't let material failure stop your production line. Identify the symptom below to find the correct steel grade.
Symptom: The cutting edge of your punch or die breaks off in small pieces (micro-chipping) rather than wearing down smoothly.
Likely Cause: The steel is too brittle (low toughness). You might be using D-3 which has huge carbides.
D-2 contains Vanadium and less Carbon than D-3. This refines the grain structure, making it tougher and less prone to chipping.
View D-2 Specs →Symptom: A spider-web pattern of fine cracks appears on the surface of your die casting mould.
Likely Cause: Thermal fatigue. The steel cannot expand and contract fast enough during heating/cooling cycles.
H-13 is specifically alloyed with Molybdenum & Vanadium to resist thermal shock. It maintains ductility even when red-hot.
View H-13 Specs →Symptom: Heavy-duty shafts or axles snap suddenly under shock loads (impact) without bending first.
Likely Cause: The material lacks core strength. Standard carbon steel (EN8) becomes brittle when hardened deeply.
EN-24 contains Nickel (1.5%). Nickel acts as a toughening agent, allowing the core to absorb shocks while the surface remains hard.

Annealing: All our tool steels are supplied in fully annealed condition (Max 255 HB) for easy machining.
Stress Relieving: Recommended after rough machining to minimize distortion during final hardening.
Black Bars: Forged or Hot Rolled surface. Economical choice for heavy machining.
Bright / Peeled: Surface defects removed. Closer tolerance. Ideal for CNC turning applications.
Forged Blocks: Supplied with +5mm to +10mm oversizing to allow for machining cleanup.
Round Bars: Generally supplied with +1mm to +3mm tolerance depending on rolling standard.
We stock material in various profiles to minimize your machining time.
Dia: 20mm to 450mm
Ideal for turning shafts, gears, and circular dies.
Size: Custom Cut from Plate
Essential for die blocks, moulds, and heavy bases.
Width: Various Sizes
Ready-to-use flats for guide rails and machine parts.
Steel looks the same on the outside. It's the internal structure that counts. Here is how we ensure you get the best.
For critical die steels (like D2 and H13 blocks), we ensure the material is UT OK. This guarantees there are no internal blowholes, cracks, or voids that could cause your expensive die to crack during heat treatment.
Most of our tool steels are supplied in the Spheroidized Annealed condition. This ensures the steel is soft enough to be easily machined, drilled, and tapped before you send it for final hardening.
We source from mills that utilize Vacuum Degassing. This creates a fine, uniform grain structure, which is crucial for achieving a high polish on molds and high toughness in gears.
