400 Series Ferritic Stainless Steel Tube TP410 For Boiler Size 19.05mm 25.4mm

400 Series Stainless Steel,TP410 ferritic Stainless Steel Tube for boiler

The 400 series group of stainless steels has an 11 percent chromium and 1-percent manganese increase, above the 300 series group. The 400 series is susceptible to rust and corrosion under some conditions. Heat-treating will harden the 400 series. The 400 series of stainless steels have higher carbon content, giving it a martensitic crystalline structure.This provides high strength and high wear resistance. Martensitic stainless steels aren’t as corrosion resistant as the austenitic types.

Typical Manufacturing Specifications:

ASTM A268

ASME SA268

Used for parts requiring a combination of good strength and toughness, plus reasonable corrosion resistance. Typical applications are: Bolts, Bushings, Fasteners, Gas Turbine Parts, Mine Equipment, Pump Parts, Petrochemical Equipment, Steam Turbine Parts, Studs, Valve Parts etc.

Material magnetic in all conditions.

410 - UNS S41000:

AISI Type 410 is a martensitic stainless steel that provides high strength and hardness with moderate corrosion resistance. A wide range of properties can be developed with different heat treatments, with ultimate tensile strengths ranging from 500 to 1400 MPa. It is magnetic in both the annealed and hardened conditions. High carbon content results in the formation of chromium carbide compounds, providing excellent wear resistance and edge retention when hardened. Additionally, this grade provides excellent high temperature oxidation and scaling resistance, yet is economical due to the low alloy content. Thermal conductivity is improved and thermal expansion reduced relative to austentic stainless grades.

Grade 410S is a ferritic stainless steel that is a lowcarbon variation of ferritic type 410 stainless steel. Due to the lower level of carbon and the addition oftitanium and/or columbium, this alloy minimizesaustenite formation at higher temperatures. This alsoprevents hardening and prevents cracking whenwelding.
