Indonesia’s tooling industry depends heavily on SKD61 tool steel, especially in automotive die casting, plastic molding, and heavy-equipment parts production. Local buyers look for materials that can handle long production hours and frequent thermal cycling without pushing costs too high—making SKD61 a natural fit for the Indonesian market. Its stable performance and accessible pricing give manufacturers a practical balance between durability and budget control. As demand for high-volume tooling grows across Java, Batam, and major industrial zones, choosing the right SKD61 supplier becomes increasingly important. This introduction sets the stage for reviewing Indonesia’s top three SKD61 manufacturers and how they support the country’s fast-expanding hot-work tooling sector.

PT United Super Steel
PT United Super Steel supplies steel materials to Indonesia’s hot-work tooling industry. They provide ED61 (SKD61) hot work tool steel—the Indonesian name for JIS SKD61. This material has become essential for die and mold makers across the country.
Product Range and Material Standards
ED61 (SKD61) comes in bars up to 300 mm diameter and plates up to 200 mm thickness. These sizes work for all tooling needs. The material meets several international standards: JIS SKD61, AISI H13, DIN X40CrMoV5-1, and GB 4Cr5MoSiV1 equivalents. This gives you flexibility with international clients. You can also source replacement parts more easily.
Performance Specifications
After heat treatment, you get 48–52 HRC hardness. Tensile strength exceeds 1,500 MPa. Yield strength reaches ≥1,300 MPa. The material keeps ≥10% elongation. Impact toughness tests show ≥20 J (Charpy V-notch). This matters for dies that face sudden thermal shocks.
Heat treatment follows proven steps: anneal at 800–850°C, quench at 1,020–1,050°C, then triple temper at 550–680°C for best toughness. While shipping the material annealed at ≤235 HBS hardness. It’s ready for machining right away.
Quality Control and Manufacturing
PT United Super Steel uses EF+LF+VD smelting process (Electric Furnace + Ladle Furnace + Vacuum Degassing). This method cuts down inclusions. It makes the material cleaner. Ultrasonic testing follows SEP 1921-84 Class 3 standards. Full material certification comes with each order for tracking.Indonesian die casters report 30–40% longer mold life versus standard hot-work steels. Switch housings, electric iron soleplates, and automotive die casting molds made with this material resist thermal fatigue better. They also resist cracking.
Supply Chain Benefits
Common sizes are in stock for fast delivery. Custom orders ship within 30–45 days. They accept T/T, L/C, D/P, MoneyGram, and PayPal. Trade terms include FOB, CIF, CFR, and FCA.Their local technical team helps with heat treatment settings and specific applications. This beats importing similar materials from overseas suppliers.
PT VISI MAJU GLOBALINDO
PT VISI MAJU GLOBALINDO serves the Indonesian die and mold market. Their SKD61 hot work tool steel ships ready for local workshops. The material comes processed for Indonesia’s tooling needs.
Material Forms and Industry Focus
The company stocks round, flat, and square bar formats. This tool steel is medium carbon and high chromium alloy. It arrives annealed and ready for machining. No preliminary heat treatment needed before cutting. The material comes at ≤235 HBS hardness. This baseline hardness makes initial machining simple.Local die makers use this SKD61 for multiple applications. Die casting dies, extrusion dies, hot forging dies, and molds for aluminum and zinc parts – all rely on this material. The square and flat bar formats suit complex die shapes well. You can machine detailed cooling channels and ejector pin holes. Hard spots won’t slow you down.
Performance in High-Temperature Operations
PT VISI MAJU GLOBALINDO’s SKD61 stays consistent during long production runs. The material fights off thermal fatigue, cracking, and wear. Dies can stay at high temperatures for hours. Indonesian mold shops run continuous shifts. They report stable sizes across thousands of cycles.This helps with complex die shapes. Thermal expansion stays predictable. Corner radii, thin ribs, and deep cavities expand and contract evenly. You skip the warping issues that come with poor-quality tool steel.
Standards Compliance and Local Advantage
The material meets JIS SKD61, AISI H13, and DIN X40CrMoV5-1 standards. This global compliance helps. Your dies can serve local clients and export makers. Foreign buyers ask for H13 tooling? PT VISI MAJU GLOBALINDO knows Indonesian workshop conditions. Their technical support speaks your language and understand local machining methods. Overseas suppliers often miss how tropical humidity affects tool steel storage. You get better support here.
E Steel Sdn Bhd (Indonesia Branch/Distributor)
E Steel Sdn Bhd supplies direct to Indonesia and broader ASEAN markets. Their Indonesian branch connects hot-work tooling makers straight to the source. No middlemen. You get faster delivery and simpler ordering for local workshops.
Product Availability and Export Reach
They stock JIS SKD61 in round bars, rods, shafts, and plate formats. These match AISI H13 and DIN 1.2344 (2344) specs. Different naming systems, same global-standard material. This helps when clients list H13 or 2344 on technical drawings.E Steel Sdn Bhd ships to Indonesia, Singapore, Brunei, and nearby ASEAN countries. No minimum order required. Small mold shops buy just what they need. No bulk buying pressure. No extra stock taking up warehouse space.
Material Condition and Applications
All SKD61 arrives annealed at ≤235 HBS hardness. Machinists can start cutting right away. The soft state makes roughing faster. Cooling channels machine quicker. Ejector systems cut easier too.Indonesian toolmakers pick this for hot work dies, extrusion dies, and die casting dies. It handles aluminum, magnesium, zinc, and copper alloys well. Forging dies and plastic injection molds that need high heat stability work great too. Rods and shafts fit ejector pins and core pins. Plates suit large die blocks.
Performance Claims and Quality Documentation
E Steel Sdn Bhd sees 30–40% longer mold life in tricky, thin-walled aluminum die casting jobs. The material responds to heat treatment the same way across batches. Dies stand up to heat shock, cracking, and wear during long production runs.Each shipment comes with full mill certification and traceability papers. You can trace material chemistry and mechanical properties back to the original melt. This paperwork covers quality audits and export needs.
Conclusion:
After comparing these three suppliers, I’ve learned that choosing the right SKD61 partner isn’t just about price—it’s about understanding your actual production needs. Whether you need PT United Super Steel’s technical depth, PT VISI MAJU GLOBALINDO’s local workshop expertise, or E Steel’s flexible ordering, each offers real value. I now see that investing time in supplier selection directly impacts my die longevity and production costs. The right SKD61 source becomes a long-term manufacturing advantage, not just a material purchase.
