Good plasticity and weldability 15-5PH polishing rod UNS S15500 forging processing in petrochemical industry
Introduction to 15-5ph precipitation hardening stainless steel:
15-5PH is a high-quality stainless steel material known for its high yield strength and hardness, moderate corrosion resistance, and high wear resistance. It is a type of high-strength stainless steel, belonging to martensitic precipitation hardening stainless steel, with excellent strength and corrosion resistance, capable of withstanding applications at high temperatures.
This alloy stainless steel has good strength and corrosion resistance, with a density of 7.75 g/cm ³ and a melting point of 1399 ℃. At high temperatures, 15-5PH stainless steel can still maintain excellent strength and toughness.

Carbon (C):≤ 0.07%
Silicon (Si): ≤ 1.00%
Manganese (Mn): ≤ 1.00%
Phosphorus (P): ≤ 0.040%
Sulfur (S): ≤ 0.030%
Chromium (Cr): 14.00% -15.50%
Nickel (Ni): 3.50% -5.50%
Copper (Cu): 2.50% -4.50%
Niobium (Nb): 0.15% -0.45%
The proportion of these elements gives 15-5PH stainless steel excellent mechanical properties and corrosion resistance. Carbon and silicon help improve the malleability and toughness of materials, while manganese has a certain impact on the strength and toughness of alloys. The low content of phosphorus and sulfur helps to improve the processability of the material.
