ASTM A268 TP410S SMLS Stainless Steel Seamless Tubes Pipes

ASTM A240 A268 ASME SA 240 SA268 410S UNS S41008 stainless steel Contains lower carbon

than Type 410, offers improved weldability but lower hardenability.

Type 410S is a general purpose corrosion and heat resisting chromium steel recommended for

corrosion resisting applications. 

The low carbon and a small alloy addition minimize austenite formation at high temperature which

restricts the ability of 410S to harden.

410S remains soft and ductile even when rapidly cooled from elevated temperature.

This helps prevent cracking when the alloy is exposed to high temperature or during welded.

410S is completely ferritic in the annealed condition.

410S is not hardenable by heat treatment. It is annealed in the 1600 - 1650°F (871 - 899°C) range

and then air cooled, mainly to relieve cold working strains. 410S stainless steel can be easily formed by drawing,

spinning, bending and roll forming.

This non-hardening characteristic helps prevent cracking when the alloy is exposed to high temperatures

or welded. It exhibits adequate corrosion resistance similar to 410 and good oxidation resistance.

This non-hardening characteristic retards formation of hardening cracks when the steel is welded.

410S is particularly useful for annealing box, quenching rack, oxidation-resistant partition and other high

temperature units.

Because 410S cools from elevated temperatures without hardening, it is particularly useful for annealing boxes,

quenching racks, oxidation resistant partitions and other high-temperature units. It also is used in the

petrochemical industry for tower packing and distillation trays. 410S is generally considered to be weldable

by the common fusion and resistance techniques.

Special consideration is required to avoid brittle weld fracture. When a weld filler is required, AWS E/ER 309L

or 430 filler material is most often specified.

Type 410S provides adequate resistance to atmospheric corrosion, fresh water, mild acids and alkalies,

and some other chemicals.
