| Element | 17-7PH |
|---|---|
| Chromium | 16.0-18.0 |
| Nickel | 6.5-7.7 |
| Manganese | 1.00 |
| Silicon | 1.00 |
What is 13 8 stainless?
hardening stainless steel
ATI 13-8™ alloy (UNS S13800) is a martensitic precipitation-hardening stainless steel that has excellent strength, high hardness, superior toughness, and good corrosion resistance. Good transverse toughness properties are achieved by tight chemical composition control, low carbon content, and vacuum melting.
What is H1000 condition?
The condition H1000 has higher aging temperature, which has as a consequence higher recovery of dislocations in a martensitic structure, coarsened Ni3Ti phase and smaller fraction of chi phase.
What pH will corrode stainless steel?
6.42 to 7.52
The effect of pH on the corrosion behavior of 316L stainless steel (SS) was investigated. The film resistance decreases and the corrosion current density increases as the pH rises from 6.42 to 7.52 for 316L SS. The corrosion rate of 316L SS increases with increasing pH in hydrogenated high temperature water at 300 °C.
What pH will corrode steel?
For typical steel/iron/cast iron, when the pH is less than about 4, protective oxide films tend to dissolve and corrosion rates increase. When the pH is between about 4 and 10, soil corrosion is independent of pH. When the pH is greater than 10, the metal becomes passive and corrosion rates decrease with increasing pH.
What is the fraction of 13-8?
Reduce 13/8 to lowest terms 138 is already in the simplest form. It can be written as 1.625 in decimal form (rounded to 6 decimal places).
What is H1000 heat treat?
This specification covers a corrosion-resistant steel product in the solution and precipitation heat treated (H1000) condition. Rationale: AMS5629/H1000 is a new specification for purchase of corrosion-resistant steel product in the solution and precipitation heat treated condition.
What type of steel is 17-4?
stainless steel
17-4 stainless steel, also known as SAE Type 630, is a common and exceptionally durable type of steel used in a diverse variety of industries and applications. The numbers “17-4” refer to its composition: ≈17% chromium and ≈4% nickel. It also can include between 3 and 5% copper.
Which is better 304 or 316 stainless steel?
Though the stainless steel 304 alloy has a higher melting point, grade 316 has a better resistance to chemicals and chlorides (like salt) than grade 304 stainless steel. When it comes to applications with chlorinated solutions or exposure to salt, grade 316 stainless steel is considered superior.
What is condition H1100?
Stainless Steel 17-4 H1100 is a precipitation-hardening martensitic Stainless Steel, which has corrosion resistance comparable to austenitic varieties. Our H1100 has been heat-treated to a minimum tensile strength of 140ksi, yield strength of 115ksi, an elongation in 2in of 14%, and a reduction of area of 45%.
What are the properties of 13-8 PH stainless steel?
It exhibits excellent strength, high hardness, superior toughness, and good corrosion resistance. Good transverse toughness properties are achieved by tight chemical composition control, low carbon content, and vacuum melting. 13-8 PH steel provides a wide range of properties through a single precipitation hardening heat treatment.
What kind of stainless steel is a 13-8?
13-8 Stainless Steel is a martensitic, high strength stainless steel with good corrosion resistance, toughness that is capable of achieving high hardness levels.
What kind of furnace melts 13-8 PH stainless steel?
13-8 PH is a martensitic precipitation-hardening stainless steel. This alloy is double melted in a Vacuum Induction Furnace (VIM) followed by Consumable Electrode Vacuum Melt (CEVM or VAR); or in some cases, 2nd melt is by Electroslag Remelting (ESR) as specified by consumer.
What makes a 13-8 stainless steel bar good?
13-8 is a precipitation-hardening stainless steel that has excellent strength, high hardness, superior toughness, and good corrosion resistance. Good transverse toughness properties are achieved by tight chemical composition control, low carbon content, and vacuum melting. Don’t see what you need?
