All About SS 15-5 Ph Bars

15-5 PH stainless steel is a precipitation-hardening martensitic stainless steel containing roughly 15% Chromium and 5% Nickel. It possesses great strength, hardness, and corrosion resistance. A single low-temperature heat treatment can boost strength even more. SS 15-5 Ph Bars It has superior transverse toughness and ductility than 17-4 PH, as well as improved mechanical characteristics in larger cross-sections and enforceability. It is easily welded. It can be machined in any of the various Thermal Conditions for this grade.

What is the definition of a 15-5 PH Stainless Steel Round Bar?

15-5 PH stainless steel was developed to be tougher than 17-4 PH stainless steel. The martensitic structure of the 15-5 alloy is enhanced by a relatively low-temperature heat treatment that precipitates a copper-containing phase in the alloy. In certain specifications, 15-5 is also referred to as XM-12.

15-5 is a chromium-nickel-copper precipitation hardening stainless steel derivative of the earlier 17-4. Both alloys have a high strength-to-weight ratio and moderate corrosion resistance. High strength is maintained up to 600 degrees F. The 15-5 alloy was created to be tougher than the 17-4 alloy. This increased toughness is obtained by lowering the delta ferrite content and controlling the size and shape of the inclusions.
