Tool Steel D2 Machining Capabilities<\/h3>\n\n\n\n\n\n\n\n\n
Capability<\/th>\nTechnical Description<\/th>\nJucheng Advantage<\/th>\n<\/tr>\n<\/thead>\n
Abrasive-Resistant Milling<\/strong><\/td>\nD2 is highly abrasive due to large chromium carbides. We use specialized coated carbide tools to rough-machine complex shapes in the annealed state.<\/td>\nOur high-torque CNC centers maintain consistent feed rates to prevent tool glazing and work hardening, ensuring efficient material removal.<\/td>\n<\/tr>\n
Hard Milling (Up to 62 HRC)<\/strong><\/td>\nFinish-machining D2 after it has been fully hardened. This process requires ultra-rigid setups and CBN or ceramic tooling.<\/td>\nAllows us to achieve tight tolerances and superior surface finishes on hardened dies, reducing the need for manual stoning.<\/td>\n<\/tr>\n
Precision Profile Grinding<\/strong><\/td>\nAchieving micron-level accuracy on D2 cutting edges and forming profiles using CNC grinding wheels.<\/td>\nJucheng guarantees edges that are sharp and durable, essential for high-volume stamping and blanking operations.<\/td>\n<\/tr>\n
EDM & Wire Cutting<\/strong><\/td>\nUsing electrical discharge machining to create intricate internal features and sharp corners in hardened D2 blocks.<\/td>\nWe specialize in Wire EDM for D2 thread rolling dies and complex punch profiles where traditional milling cannot reach.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Fabrication Guidelines for Tool Steel D2<\/h3>\n

Machinability Challenge:<\/strong>
\nD2 is one of the more difficult tool steels to machine (approx. 45% machinability compared to A2). Tip:<\/strong> It is highly abrasive; expect higher tooling costs and slower cycle times during the roughing stage.<\/p>\n

Heat Treatment Strategy:<\/strong>
\nD2 is an air-hardening steel with very high chromium content. Tip:<\/strong> To reach its peak hardness of 60-62 HRC, we recommend vacuum hardening followed by double tempering to ensure dimensional stability and maximum toughness.<\/p>\n

Grinding Sensitivity:<\/strong>
\nDue to its high carbide content, D2 is susceptible to “grinding cracks” if the wheel is too hard or feed is too aggressive. Tip:<\/strong> We use soft-bond wheels and abundant coolant to protect the surface integrity of your dies.<\/p>\n

Semi-Stainless Property:<\/strong>
\nWith 12% Chromium, D2 offers better corrosion resistance than most other tool steels, but it is not a true stainless steel. Tip:<\/strong> It still requires oiling or protective coatings in humid environments to prevent pitting.<\/p>\n<\/div>\n

Primary Applications<\/h3>\n

Blanking & Stamping Dies<\/strong>
\nThe standard choice for long-run dies that must cut hard materials while maintaining a sharp edge over millions of cycles.<\/p>\n

Thread Rolling Dies<\/strong>
\nUsed to form threads on bolts and screws. D2’s extreme hardness and compressive strength prevent the die profiles from collapsing.<\/p>\n

Industrial Knives & Slitters<\/strong>
\nPaper cutters, wood chippers, and plastic granulator blades that require the ultimate in abrasion resistance.<\/p>\n

Master Gauges<\/strong>
\nChecking fixtures and gauges that must resist wear from constant contact with production parts.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
