Call - 800-748-9811 Frequently Asked Questions What is 15-5 PH stainless steel? + 15-5 PH (UNS S15500) is a martensitic precipitation-hardening stainless steel containing 14-15.5% chromium, 3.5-5.5% nickel, and 2.5-4.5% copper, with a niobium addition. It is aged at temperatures from 900°F (H900) to 1150°F (H1150) to develop mechanical properties, similar to 17-4 PH but with improved through-thickness toughness in thick sections due to vacuum arc remelting (VAR) production. What is the difference between 15-5 PH and 17-4 PH? + 15-5 PH and 17-4 PH have similar nominal compositions, but 15-5 PH is produced by VAR or ESR remelting, which refines the microstructure and significantly improves through-thickness toughness and transverse properties. This makes 15-5 PH the preferred choice for thick plate applications such as aircraft bulkheads where 17-4 PH can show directional property differences. What are the properties of 15-5 PH plate? + 15-5 PH plate offers very high strength (H900: 190 ksi tensile, 170 ksi yield), excellent toughness in thick sections versus 17-4 PH, good corrosion resistance comparable to 304 in mild environments, good machinability in Condition A, and a range of strength-toughness combinations via aging conditions. What is 15-5 PH stainless steel used for? + 15-5 PH plate is used in aerospace bulkheads, wing fittings, and structural frames; nuclear reactor components; chemical processing vessels; food processing machinery; and petrochemical valve and pump bodies -- wherever very high strength, good toughness, and adequate corrosion resistance are all required simultaneously. What is the tensile strength of 15-5 PH? + H900 condition: approximately 190 ksi tensile, 170 ksi yield, 35-45 HRC. H1025: ~155 ksi tensile, ~145 ksi yield. H1075: ~145 ksi tensile. H1150: ~125 ksi tensile. Each step-up in aging temperature reduces strength and hardness while improving ductility and toughness. Can 15-5 PH be machined? + Yes, 15-5 PH machines well, especially in Condition A (solution-annealed, softest state). After aging to H900-H1025, carbide tooling handles it well. Parts are typically rough-machined in Condition A, then finish-machined after aging. Can 15-5 PH be welded? + Yes, 15-5 PH can be welded using TIG with ERNi-1 or AWS ER630 filler. Post-weld solution annealing followed by re-aging is recommended to restore full mechanical properties across the weld and heat-affected zone. What are the aging conditions for 15-5 PH? + Standard aging conditions: H900 (900°F/482°C, 1 hr), H1025 (1025°F/552°C, 4 hrs), H1075 (1075°F/579°C, 4 hrs), H1100 (1100°F/593°C, 4 hrs), H1150 (1150°F/621°C, 4 hrs). H900 gives maximum hardness; H1150 gives best ductility and toughness. Does Stainless Shapes supply 15-5 PH with certifications? + Yes, Stainless Shapes distributes 15-5 PH plate per AMS 5659. Full certified material test reports (CMTRs) confirm chemistry, mechanical properties, and heat number traceability. Contact Stainless Shapes at 800-748-9811 for current stock and quoting. What is the corrosion resistance of 15-5 PH? + 15-5 PH has moderate corrosion resistance, generally comparable to 304 stainless in mild to moderately corrosive environments. It is not as corrosion-resistant as 316 in chloride-rich or marine environments. For applications requiring both very high strength and aggressive corrosion resistance, duplex grades or nickel alloys should be evaluated.
