Alloy 410S (UNS S41008) is a low carbon, non–hardening modification of Alloy 410 (UNS S41000) the general purpose 12% chromium martensitic stainless steel. The low carbon and a small alloy addition minimize austenite formation at high temperatures which restricts the alloys ability to harden. 410S remains soft and ductile even when rapidly cooled from above the critical temperature. This non-hardening characteristic helps prevent cracking when the alloy is exposed to high temperatures or welded. 410S is completely ferritic in the annealed condition. It exhibits adequate corrosion resistance similar to 410 and good oxidation resistance.
APPLICATIONS:-
Petroleum Refining and Petrochemical Processing
Columns
Distillation trays
Heat exchangers
Towers
Ore Processing
Mining machinery
Thermal Processing
Annealing boxes
Partitions
Quenching racks
Gate valves
Press plates
OXIDATION RESISTANCE
Good oxidation resistance.
Can be used in continuous service up to 1300°F (705°C).
Scaling becomes excessive above 1500°F (811°C) in intermittent service.
CORROSION RESISTANCE
Corrosion resistance of 410S stainless steel is similar to type 410.
Resists corrosion in atmospheric conditions, fresh water, mild organic and mineral acids, alkalis and some chemicals.
Exposure to chlorides in everyday activities (e.g., food preparation, sports activities, etc.) is satisfactory when proper cleaning is performed after exposure to use.
HEAT TREATMENT
The alloy can not be hardened by heat treatment. It is annealed between 1600 – 1650°F (871 – 899°C), and then air cooled to relieve cold working stresses. 410S should not be exposed to temperatures above 2000°F (1093°C), due to embrittlement. If large grains are found after annealing mildly cold-worked material, the annealing temperature should be decreased to 1200 – 1350°F (649 – 732°C).
WELDING
410S is generally considered to be weldable by the common fusion and resistance techniques. Special attention should be given to avoid brittle weld fractures during fabrication; this includes minimizing discontinuities, maintaining low weld heat input, and occasionally warming the part somewhat before forming. 410S is generally considered to have slightly poorer weldability than the most common ferritic stainless steel grade 409. A major difference can be attributed to the addition of alloy, to control hardening which results in the need for higher heat input during welding.

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.
