Stainless Steel 410S Flanges, UNS S41008 Flanges Supplier & Exporter

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.
