High Chromium Ferritic Stainless Steel Tube Seamless High Mechanical Strength
ASTM A268 TP410 3/4'' X BGW14 X 7315MM Seamless Martensitic Stainless Steel Tube
TP410 is a basic straight chromium high hardenability martensitic stainless steel with good strength and fairly good corrosion resistance as generally supplied hardened and tempered in the tensile range 700 - 850 Mpa (condition R) Brinell range 201 - 255.Characterised by good corrosion resistance in mild atmospheric industrial and domestic environments coupled with good strength and excellent toughness in the hardened and tempered condition. 410 due to its excellent hardenability is capable of being through hardened to over Rc40 depending upon carbon content and section size. Small sections can be air cooled and larger sections oil quenched for maximum through hardness.Pre hardened and tempered 410 will also respond readily to nitriding achieving a typical surface hardness of over Rc65. The nitriding process however reduces the corrosion resistance and is therefore not generally recommended except for critical applications where the benefit outweighs all other considerations.
