Description
Custom 455 Round Bars
Custom 455 Round Bars is a martensitic age hardenable stainless steel, which has properties of high strength and good corrosion resistance. Custom 455 is relatively soft and formable in the annealed condition, however through a single-stage aging treatment alloy 455 develops an exceptionally high yield strength with good ductility and toughness.
Custom 455 is a high-strength alloys with good corrosion resistance to atmospheric environments, and a martensitic age-hardenable stainless steel. This alloy is relatively soft and formable in the annealed condition. Asingle-step aging treatment develops exception-alloy high yield strength with good ductility and toughness.
This stainless can be machined in the annealed condition , and welded in much the same manner as other precipitation hardenable stainless steels. Because of its low work-hardening rate, it can be extensively cold formed.
Custom 455 stainless represents a significant advancement in the area of precipitation hardening stainless steels. It should be considered where simplicity of heat treatment, ease of fabrication, high strength and corrosion resistance are required in combination.
Custom 455® is a martensitic, age-hardenable stainless steel. This alloy represents a significant advancement in precipitation hardening stainless steel. Custom 455® has three times the yield strength of standard 304. It lends itself well to heat treatment and fabrication and has exceptionally high yield strength, good ductility, and toughness. Custom 455® resists staining in normal atmospheres and shows no corrosion in freshwater.

Applications of Custom 455 :
Custom 455 is used in various fields, including medical devices and instruments, needles, pins, food processing and handling, and heat exchangers and conveyors.
- • Drill bits
• Drivers
• Distractors
• Shafts
• Surgical instruments for orthopedic, spinal, and dental markets
Heat Treatment :
• Condition A – (Solution Treated or Annealed): Heat to 1500/1550 °F, and cool rapidly. Water quenching is preferred for small sections. Custom 455 stainless will normally be supplied from the mill in the annealed condition, ready for the one-step hardening treatment.
• Condition H 900, H 950, H 1000, H 1050 – (Precipitation or Age Hardened): The high strength levels of Custom 455 are derived from a single precipitation-hardening treatment consisting of heating to a selected temperature between 900/1050 °F, holding for 4 hours and air cooling
