1.4542 S17400 630 17-4PH Precipitation Hardening Stainless

Alloy 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). 17-4PH Stainless Steel-Introduction, Applications, Data Sheet17-4PH is a precipitation hardened (PH) martensitic stainless steel consisted of copper and niobium/tantalum. This grade features high strength, hardness and corrosion resistance. Its mechanical properties can be optimized by heat treatment with the compression strength achieving up to 1100-1300 mpa (160-190 ksi).

A Guide to Precipitation-Hardening Stainless Steel Alloys

A typical cycle might consist of heating to very high temperatures, 995°C (1750°F); cooling to -75°C (100°F) to effect the transformation to a martensitic structure; holding for three to eight hours, then precipitation-hardening between 450 and 565°C (840 and Alloy 17-4 PH High Strength Stainless Steel Broder Aug 02, 2017 · Alloy 17-4 PH is a chromium-copper precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions.. 17-4PH Stainless Steel combines high strength, hardness (up to 572°F / 300°C), and moderate corrosion resistance.Alloy 17-4 PH withstands corrosive attacks better than any of the standard hardenable stainless steels and is comparable to Alloy 304 in most media. PRODEC® 17-4 - Rolled Alloys, Inc.As a result, improved machining properties are realized in all heat treated conditions (Condition A, H1150, H1025, etc.) PRODEC 17-4 round bar is produced in diameters ranging from 9/16" to 6-1/2". 17-4 is also commonly referred to as type 630 stainless. It is a martensitic, precipitation hardening stainless steel.

Precipitation Hardening Stainless Steels - TWI

The martensitic PH steels, of which 17/4PH is the most common, transform to martensite at low temperatures, typically around 250°C, and are further strengthened by ageing at between 480 and 620°C. The austenitic-martensitic PH steels are essentially fully austenitic after solution treatment and require a second heat cycle to 750°C/2 hours before cooling to room temperature to form martensite. Technical Data Sheet304 stainless steel in most media. In general, the corrosion resistance of ATI 17-4 alloy is superior to that of the hardenable 400 series stainless steels. As with other precipitation hardening stainless steels, ATI 17-4 precipitation hardening stainless steel is more susceptible to stress corrosion cracking at peak strength.

    17-4 PH Alloys International, Inc.17-4 PH Steel contains 4% copper and may be hardened by a single low-temperature precipitation hardening heat treatment, producing excellent mechanical properties at a high strength level. 17-4 PH provides this high strength in combination with good mechanical properties

    Understanding the Difference:17-4 PH vs. 17-7 PH

    Type 17-4 PH stainless steel is the most widely used of all of the precipitation-hardening stainless steels. It includes the addition of Chromium, Nickel, Copper and Niobium, making it a truly martensitic microstructure. It is further strengthened by a low temperature treatment which precipitates a copper containing phase in the alloy. In comparison to other PH alloys, 17-4 PH requires a simple heat 17-4 PH Steel AK SteelAK STEEL 17-4 PH® STAINLESS STEEL is the most widely used of all the precipitation-hardening stainless steels. Its valuable combination of properties gives designers opportunities to add reliability to their products while simplifying fabrication and often reducing costs.
