Stainless Steel - 17-4 Annealed 17-4 (PH) Precipitation Hardening Alloy (S17400), Type 630, is a chromium-nickel-copper precipitation hardening stainless steel used for applications requiring high strength and moderate level of corrosion resistance. High strength is maintained to approximately 600ºF (316ºC). The corrosion resistance of 17-4 Precipitation Hardening Alloy is comparable to that
17-4 and condition A - Metal and Metallurgy engineering Feb 01, 2005 · The beauty of 17-4 was never having to use a furnace, just use an oven. We have used 17-4 from its introduction in all forms and conditions and have never had to solution anneal any component. The above comments about hardness and strength levels certainly apply.
Type 17-4 PH stainless steel contains between 15-17.5% of chromium in its composition. In this regard, a seagoing vessels pump and valve parts are made of type 17-4 PH stainless steel. Most of the parts of that ship that you went on that annual cruise are made from type 17-4 PH stainless steel.
Alloy 17-4 PH Precipitation Hardening - Sandmeyer Steel
General PropertiesCorrosion ResistanceMechanical PropertiesAlloy 17-4PH (UNS S17400), Type 630, is a chromium-nickel-copper precipitation-hardening martensitic stainless steel with an addition of niobium. 17-4PH combines high strength and hardness with good corrosion resistance. The alloy is furnished in the solution annealed condition (Condition A). It should not be used at temperatures above 572°F (300°C) or for cryogenic service. Optimal mechanical properties can be obtained by subjecting the alloy to age hardening heat treatments. Heat treatment in the 900°F (Heat Treating Stainless Steels Table Chart Engineers Stainless steels are heat-treated based on the stainless steel type and the target end item requirements. Heat treatment methods, such as stress relieving, hardening and annealing, strengthen the ductility and corrosion resistance properties of the metal that is modified during fabrication, or generate hard structures capable of tolerating abrasion and high mechanical stresses.
Annealed Stainless Steel McMaster-CarrHigh-Strength 17-4 PH Stainless Steel With a higher chromium content than 15-5 PH stainless steel, this high-strength 17-4 PH offers better corrosion resistance. It is also known as 630 stainless steel.
304 is miserable. If it is possible, change to 303. If not, is it possible to relieve the bore so the whole 3/4" is not tapped. The other area to look at is taps that are specifically for stainless. Check the catalogs or suppliers, there are taps available that have a much shorter cutting area, and black oxide finish for stainless.
Confused about Annealing / Heat Treating Terminology The proper method of annealing temperature, time and rate of cooling depends on the type of alloy. Most austenitic stainless steels are annealed at a minimum temperature of 1900° F (1038° C) followed by water quenching or rapid cooling. Martensitic steels are annealed at lower temperatures (around 1400° F/760° C) and slow cooled.

Heat treating 17-7PH Stainless Steel:Q & A'sJul 15, 2008 · A. 17-7PH Cond. A- You guys are wrong. Rules dictate that 17-7 in the annealed state can only attain a maximum yield at RH900. Condition C.- which is attained by cold reduction is supposedly the only way to reach CH900. Due to the fact that mills thumb their noses at "small buys" of 17-7PH sheet, bar etc.- only condition A is available.
STAINLESS STEELDec 13, 2016 · 17-4 PH Stainless Steel provides excellent mechanical properties. For applications requiring high strength and hardness plus corrosion resistance, this alloy is an outstanding choice. In addition, it is more cost effective than many high-nickel, non-ferrous alloys.

Slaying Stainless Steel:Machining Guide - In The LoupeJun 19, 2018 · Finishing end mills for stainless steel will have a helix angle over 40 degrees, and a flute count of 5 or more. For more aggressive finishing toolpaths, flute count can range from 7 flutes to as high as 14. Below is a great example of a finishing run in 17-4 Stainless Steel.
Solution Annealing of Forgings - ThermTechSome materials, such as 17-4 stainless steel & some Inconels, are solution annealed as a pre-treatment for age hardening. This ultimately provides the required mechanical properties for the part application. Recommendations. Selection of the proper atmosphere is a critical factor when choosing proper processing parameters for solution annealing.
The above values are average and may be considered as representative of 17-4 stainless. APPLICATIONS. 17-4 is used where high strength and good corrosion resistance are required, as well as for applications requiring high fatigue strength, good resistance to galling, seizing and stress corrosion. Machinability in the annealed condition is
Heat treating 17-4 stainless - Practical MachinistSep 28, 2016 · Can I buy 3/16 dia annealed 17-4 stainless then heat treat after machining. I did some research and sources say it is a precipitation heat treating. Heat the parts to 1150 degrees and hold for 4 hours then quench in still air. My heat treater says it will cost $150 to heat treat 25 pieces 3/16 dia X 5" long. Can I heat treat these parts in my own heat treat oven.
