17-4 PH Stainless Steel is a precipitation hardening martensitic stainless steel. Typical usage is seen in applications requiring high strength and a modest level of corrosion resistance. Strength and toughness desired can be manipulated by temperate range in the heat treatment process.

Below you will find typical applications of 17-4 PH stainless steel as well as the metals composition and mechanical properties. Learn more about or value added services that we offer to help you expedite the current job you have at hand.

Best Stainless offers high quality standards including: UNS S17400, AMS 5643, ASTM A564, and ASTM A693 Grade 630.

17-4 PH stainless steel can be used for a variety of applications including: pump shafts, oil path, mechanical seals, and within the aerospace industry. Its composition is carbon, chromium, columbian + tantalum, copper, manganese, nickel, phosphorous, silicon, and sulfur.

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.

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.

STAINLESS STEEL 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.


MANUFACTURING SPECIFICATIONS:

  • ASTM A182M (3000lb NPT and socket weld).
  • ANSI B16.3 (BSP dimensions)
  • ISO 4144 (BSP dimensions)

STAINLESS STEELS FITTINGS AND FLANGES:

A flange is a ring of steel (forged, cut from plate, or rolled) designed to connect sections of pipe, or to join pipe to a pressure vessel, valve, pump or other integral flanged assembly. Flanges are joined to each other by bolts, and to the piping system by welding or threading (or loose when stub ends are used). Forged stainless steel flanges are designed to the following common pressure ratings, stainless steel flanges are exported by Harsh Steel in Classes 150, 300, 600, 900, 1500 and 2500. Standard sealing face is Raised Face (RF).
The basic types of flanges are:

  • Stainless steel slip-on flange
  • Stainless steel socket weld flange
  • Stainless steel blind flange
  • Stainless steel lap joint flange
  • Stainless steel weld neck flange
  • Stainless steel threaded flange
  • Stainless steel orifice Flange

Manufacturing specification: ASTM A182M
Plate stainless steel flanges are cut and machined from plate - Table 'D', Table 'E', etc.
Manufacturing specification: AS2129.
Types and applications of Stainless steel and Nickel alloy flanges

Slip-on flanges The flange is slipped over the pipe and then welded both inside and outside to provide sufficient strength and prevent leakage. Slip-on flanges are also used as loose back-up flanges when stub ends are used.
Blind flanges This is a flange without a centre bore, used to shut off a piping system or vessel opening
Weld neck flanges This is a flange without a centre bore, used to shut off a piping system or vessel opening
Lap joint flanges This is again similar to a slip-on flange, but has a radius at the intersection of the centre bore and the flange face to accommodate a lap stub end.
