It is one of the most widely used precipitation hardening grades, as it has high strength hardness up to about 572°F while demonstrating good corrosion resistance in all heat treated conditions. Alloy 17-4 has adequate resistance to atmospheric corrosion or in diluted acid salts where its corrosion resistance is equivalent to Alloy 304 or 430.

hardening stainless steel that provides high strength and hardness, excellent fatigue properties, good corrosion resistance and minimum distortion upon heat treatment. It is easily formed in the annealed condition, then hardened to high strength levels by simple heat treatments to Conditions RH 950 and TH 1050. The exceptionally high
17-7 PH® Stainless Steel, UNS S17700condition and martensitic in the hardened condition. Alloy 17-7 PH® provides high strength and hardness, excellent fatigue properties, good corrosion resistance and minimum distortion upon heat treatment. It is easily formed in the annealed condition, then hardened to high strength levels by simple heat treatments to Conditions RH 950 and TH
CarTech Custom465®StainlessThe high strength levels of Custom 465 stainless are derived from a single age hardening step consisting of heating to a selected temperature between 900/1150°F (482/621°C) and holding for four to eight hours.
The effects of altering the standard H1150 heat treatment on the yield and tensile strength were found to be slight. These effects are summarized in Figure 5, which is a plot of strength v s heat treatment. The results indicate that slightly higher values of strength may be obtained by decreasing the aging time. Figure 6 shows a 2000
Homogenization Heat Treatment to Reduce the Failure of Jan 18, 2012 · Fig. 13 shows the fracture surfaces of the failed sample before homogenization (Fig. 13(a)), the sample after the homogenization heat treatment at 1100 °C for 2 h followed by cooling in furnace (Fig. 13(b)), and the sample after the homogenization heat treatment at 1100 °C for 2 h followed by cooling in air (Fig. 13(c)).
How to Determine the Best Heat Treatment for Your Parts For parts with additional heat treat processes used to modify surface properties, quench and temper determine a parts core properties such as hardness, strength, and ductility.
Feb 28, 2012 · During H950 (600) treatment, the hardness decreases significantly after the peak hardness. H950 (600) and H950 (485) treatments only have a difference on aging temperature, namely aging at 600 °C and 485 °C, respectively. When the aging time is 64 h, H950 (485) treatment reaches its peak hardness with a value of 498.3 ± 3.1 HV2.
Stainless Steel - Heat Treatment - AZoMJan 02, 2002 · 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. Heat treatment of stainless steels is mostly carried out under

In condition H 950, PH 13-8 Mo stainless has rusting resistance similar to that of Type 304 Stainless in 5 weight percent salt fog. In strongly oxidizing and reducing acids and in atmospheric exposures, the general-corrosion resistance of PH 13-8 Mo stainless approaches that of Type 304. As with other precipitation hardening stainless steels, the alloy's level of general-corrosion reistance is greatest in
