Capability<\/th>\nTechnical Description<\/th>\nJucheng Advantage<\/th>\n<\/tr>\n<\/thead>\n
Hard Machining<\/strong><\/td>\nMachining 17-4 PH after heat treatment (Condition H900, ~44 HRC). Requires rigid machines and specialized carbide.<\/td>\nWe eliminate post-heat treat distortion issues by machining the part directly in its hardened state for maximum accuracy.<\/td>\n<\/tr>\n
Heat Treatment Management<\/strong><\/td>\nProcessing parts from Condition A (Annealed) to various aged conditions (H900, H1025, H1150) to tune strength\/ductility.<\/td>\nWe provide turnkey manufacturing, handling the aging process and certifying the final hardness and tensile strength.<\/td>\n<\/tr>\n
Precision Grinding<\/strong><\/td>\nPost-machining cylindrical or surface grinding to achieve bearing-grade tolerances (+\/- 0.002mm).<\/td>\nEssential for aerospace actuator shafts and pump components where seal fits are critical.<\/td>\n<\/tr>\n
Complex 5-Axis Milling<\/strong><\/td>\nMilling structural brackets and fittings from solid 17-4 blocks.<\/td>\nOur powerful spindles easily handle the high cutting forces required for this tough aerospace alloy.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Fabrication Guidelines for 17-4 PH<\/h3>\n

Machinability:<\/strong>
\nIn the annealed state (Condition A), 17-4 PH machines similarly to Stainless 304 but is slightly harder. Tip:<\/strong> Tool life is shorter than 304; use premium coated carbide tools.<\/p>\n

Dimensional Change:<\/strong>
\nOne of 17-4’s best features is its low distortion during heat treatment. Unlike carbon steels, it shrinks very predictably (approx. 0.0005 in\/in). Tip:<\/strong> We can often machine to final size before heat treat for H1150 condition.<\/p>\n

Magnetic Property:<\/strong>
\nUnlike 304\/316, 17-4 PH is magnetic<\/strong>. Tip:<\/strong> This allows us to use magnetic workholding for surface grinding, reducing tooling costs.<\/p>\n<\/div>\n

Primary Applications<\/h3>\n

Aerospace & Defense<\/strong>
\nActuators, landing gear components, and structural fasteners requiring high strength up to 315\u00b0C (600\u00b0F).<\/p>\n

Oil & Gas<\/strong>
\nValve stems, pump shafts, and downhole tool components that need high hardness to resist wear and slurry erosion.<\/p>\n

Power Generation<\/strong>
\nTurbine blades and nuclear reactor components due to excellent corrosion resistance and mechanical properties.<\/p>\n

Medical Instruments<\/strong>
\nSurgical tools requiring a sharp cutting edge (hardness) combined with rust resistance (sterilization).<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
