Introduction
SUS410 1Cr17Mo is a kind of martensitic stainless steel which contain chromium, molybdenum, and manganese. It has a comparatively higher hardness and toughness than Austenitic and Ferritic grades and has a low coefficient of thermal expansion. In addition, SUS410 has higher strength and wear resistance due to the high carbon content. It is widely used in various industrial and household applications such as cutlery, tableware, kitchen accessories, medical tools, pump shafts, valve components, etc.
Chemical and Physical Properties
SUS410 1Cr17Mo is composed of the following elements: iron (Fe), carbon (C), chromium (Cr), molybdenum (Mo), manganese (Mn), phosphorus (P), sulfur (S), and silicon (Si).
Its chemical composition is as follows: Fe - 73.3-74.2%; C - 0.14-0.20%; Cr - 16-18%; Mo - 0.50-0.80%; Mn - 1.00%; P - 0.030%; S - 0.015%; and Si - 0.50%.
The physical properties of SUS410 1Cr17Mo are as follows: density - 7.8 g/cm3; melting point - 1398-1453°C; tensile strength - 540-560 MPa; yield strength - ≧165 MPa; elongation limit - ≧20%; and Hardness - ≧160 HB.
Specifications
SUS410 1Cr17Mo is used in various specifications of modern standards such as JIS G 4303-2005, ASTM A666, and ASTM A276. JIS G 4303-2005 includes the grades SUS410, SUS416, SUS420, and SUS430. ASTM A666 has SUS410 and SUS420 grades and ASTM A276 has general and special grades of SUS410 and SUS420.
