PRECIPITATION HARDENING STAINLESS STEEL 17-7PH BOLTS GENERAL PROPERTIES:
Stainless Grade 17-7 PH is a precipitation hardening stainless steel that provides high strength and hardness, excellent fatigue properties, good corrosion resistance, good formability, and minimum distortion upon heat treatment. The alloy provides valuable property combinations particularly well suited for aerospace applications. This special alloy also provides benefits for other applications requiring high strength and good corrosion resistance, as well as excellent properties for flat springs at temperatures up to 600°F (316°C).
PRECIPITATION HARDENING STAINLESS STEEL 17-7PH BOLTS APPLICATIONS:
- applications requiring good strength, corrosion resistance and mechanical properties up to 800 F in service.
- used for very detailed, intricate parts due to its low distortion in heat treatment.
- commonly found in a variety of springs and washers.
PRECIPITATION HARDENING STAINLESS STEEL 17-7PH BOLTS CORROSION RESISTANCE:
Corrosion resistance of Type 17-7PH stainless steel in all heat treated conditions, like other types of stainless steels – will develop superficial rust in some environments. For example, in a marine atmosphere, stainless steels show evidence of rusting after relatively short exposure periods. However, after exposure of one or two years, the amount of rust present is little more than that present at six months. As with all martensitic steels, 17-7PH stainless steel may be subject to cracking when exposed under stress in environments containing hydrogen sulfide. Such applications are not recommended.
PRECIPITATION HARDENING STAINLESS STEEL 17-7PH BOLTS FORMABILITY:
In Condition A, the alloy can be formed comparably to Type 301. It work hardens rapidly and may require intermediate annealing in deep drawing or in forming intricate parts. Springback is similar to that of Type 301. This alloy is extremely hard and strong in Condition C. Therefore, fabrication techniques for such material must be used.
PRECIPITATION HARDENING STAINLESS STEEL 17-7PH BOLTS WELDABILITY:
The precipitation hardening class of stainless steel is generally considered to be weldable by the common fusion and resistance techniques. Special consideration is required to achieve optimum mechanical properties by considering the best heat-treated conditions in which to weld and which heat treatments should follow welding. This particular alloy is generally considered to have poorer weldability compared to the most common alloy of this stainless class, 17-4 PH stainless steel. A major difference is the high Al content of this alloy, which degrades penetration and enhances weld slag formation during arc welding. Also, the austenite conditioning and precipitation hardening heat treatments are both required after welding to achieve high strength levels. When a weld filler is needed, 17-7 PH is most often specified.

Fittings and Flanges for Stainless Steel Pipe
Stainless steel piping systems can be joined by butt welding and, in the heavier 40S and 80S schedules, with threaded connections.
PRECIPITATION HARDENING STAINLESS STEEL 17-7PH BUTT WELDING STAINLESS STEEL PIPE FITTINGS
Harsh steel stocks butt welding fittings in the following configuration.
- Elbows 45 degree and 90 degree - long radius and short radius.
- Return bends 180 - long radius and short radius.
- educers - concentric and eccentric.
- Tees - equal and reducing.
- Caps.
- Stub ends - Type B.
Advantages of stainless steel butt Weld fitting to the pipe are to keep pipes permanently leak proof. The continuous structure helps strength between pipes and fittings. It reduces pressure and also minimises the action of corrosion and erosion. Butt welding fittings can be supplied in either seamless or welded construction and are covered by specifications ASTM A403M and ASTM A815M for Duplex grades.
PRECIPITATION HARDENING STAINLESS STEEL 17-7PH SCREWED AND SOCKET WELD FITTINGs
Stainless steel piping systems can be connected using stainless steel screwed fittings - BSP threaded ("150lb") low pressure stainless steel fittings and NPT class 3000 high pressure stainless fittings in Grade 316. Socket weld fittings are used in high pressure piping systems and available in grade 316L to suit schedule 80S wall thickness piping.

Harsh Steel produces duplex fasteners in all grades of duplex, to customer specification. Duplex grades are a mixed microstructure of Austenite and Ferrite, combining the properties of both (hence the name DUPLEX). Duplex stainless steels have high corrosion resistance as well as a high strength. Mechanical properties are around double that of a typical austenitic grade such as 316. They would also normally offer higher stress cracking resistance in Chloride solutions for example. They are composed typically of 22% Chromium, 5 % nickel. Having worked with duplex since its outset, the duplex bolting continues to account for a core part of our business, along with Super duplex.

Harsh Steel’s substantial experience in working with high nickel alloys bolting is crucial as they are extremely difficult materials to machine and can require various forms of additional treatment to ensure full conformity. Related by their high percentage of nickel in their composition, these highly corrosion-resistant materials are widely used in the petrochemical and offshore sector, and are often better known by their registered trade names (e.g. Inconel®, Hastelloy®, Monel® and Nimonic®).
