17 4 PH
17 4 PH is the most widely used precipitation-hardening stainless steel. It’s relatively inexpensive to alternatives and has great strength. 17 4 is best used due to its high strength, good corrosion resistance, and good properties up to and including 600 degrees.
17 4 PH stainless steel can be used for a variety of industries including: pump shafts, oil path, mechanical seals, and within the aerospace industry. This versatility has made it one of the most marketable and thus one of the best priced stainless alloys on the market.
Traits of 17 4 PH
High Strength – This alloy has a great yield rate in high-strength situations. It is a wonderful alternative to the most expensive high-nickel and non-ferrous alloys on the market. The most important aspect is noting that the strength is maintained regardless of temperature and is able to remain consistently strong across the board.
Good Corrosion Resistance – It’s wide usage in petrochemical, petroleum, paper, and food processing industries show that this metal has great corrosion resistance. It withstands corrosive degradation better than most standard stainless steels even rivalling 304 in this quality.
Good Properties up to 600 – In the lab, the test temperatures for this stainless is remarkable. By maintaining its properties through 600 degrees, we are able to determine that this metal is able to withstand heat variances without losing strength over time, while at the same time they do lose out a little bit on hardness.
Special Note: f there are potential risks of stress corrosion cracking, the higher aging temperatures then must be selected over 1022°F (550°C), preferably 1094°F (590°C). 1022°F (550°C) is the optimum tempering temperature in chloride media.
