Stainless Steel 17-4PH

• 17-4PH is a precipitation-hardening martensitic stainless steel alloy with superior corrosion and strength properties.
• It contains 15-17.5% chromium, 3-5% nickel, 3-5% copper and 1% manganese for unique characteristics.
• It can be hardened by a simple one-step aging treatment at 900-1150°F (425-615°C).
• High tensile strength and fatigue limit make it suitable for durable products.
• Corrosion resistance gives it up to 5 times longer lifespan compared to conventional materials.
• Low maintenance costs due to long-term use capabilities.

• Stainless steel 17-4PH is an excellent material for manufacturing due to its superior corrosion resistance and high tensile strength, making it ideal for applications in extreme environments or precision equipment.
• Its anti-corrosion features make it environmentally friendly.
• However, its resistance to carburization can be compromised with extended exposure to higher temperatures, while weld decay may occur in moderate temperature conditions.
• Additionally, the alloy may be more expensive than other materials due to its special heat treatment process.

• It offers corrosion resistance, superior wear resistance, higher durability, and good formability.
• It can be machined by cold sawing, grinding heat-treating, EDM (Electrical Discharge Machining), or Turning. It can also be welded using TIG welding techniques.
• Special tools are required for machining it; additionally, the temperature must be stabilized when welding it due to its susceptibility to thermal shock.
• Proper finishing techniques should always be implemented to maximize performance and longevity when used in harsh environments.

• 17-4PH is a precipitation-hardened stainless steel composed of iron, chromium, nickel, carbon, and manganese, known for its exceptional strength and hardness.
• It has superior resistance to stress corrosion cracking, making it suitable for heavy-duty applications.
• Due to its higher alloy content, 17-4PH achieves its maximum hardness when heat treated between 400°C-600°C whereas other stainless steels do not require this additional step in order to achieve their maximum hardness. This makes 17-4PH suitable for manufacturing components that require a very hard surface, such as aerospace parts or medical tools.
• Its composition can include added elements such as titanium or copper to increase wear resistance further.
• Its properties make it an optimal choice for oil & gas, food services & processing equipment, automotive parts manufacturing, and extreme environment-demanding applications.

• Stainless steel 17-4PH is an exceptional material for construction due to its impressive strength and endurance limit, with a tensile strength of 1100Mpa and a Yield Strength of 1035 Mpa.
• Its properties can be improved through heat treatment processes such as aging, solution treating, and precipitation hardening, which can cause up to 30% increase in hardness and improved corrosion resistance.
• Obtains different Rockwell C hardness values depending on heat treatment processes, generally ranging from 35-45; offers greater wear resistance and durability in industrial applications.
• Offers numerous benefits for construction over other materials due to its excellent corrosion resistance properties; suitable for many industries due to its ability to obtain various levels of hardness.

• Hinderer chose to use stainless steel 17-4PH for the nibs of their pens due to its excellent wear and corrosion resistance properties.
• The high hardness level (up to 45 on the Rockwell C scale) achieved when subjected to heat treatment processes makes it much more durable than other commonly used metals in pen nib manufacturing, such as brass or aluminum alloys.
• Additionally, it offers superior corrosion resistance, which ensures that the nib will remain in pristine condition for many years of use without being affected by moisture or other external factors.
