X14CrMoS17 (1.4104) +C900現貨價格查詢
DIN EN 1.4104 stainless steel (X14CrMoS17) is a kind of martensitic stainless steel containing molybdenum. The higher sulfur content makes it more suitable for machining. It has good machining properties, good mechanical properties, and good magnetic properties. However, the addition of sulfur reduces its weldability and corrosion resistance.
EN 1.4104 stainless steel properties and specifications are summarized in the following tables including chemical composition, mechanical properties, hardness, heat treatment, etc.
Table-1, X17CrNi16-2 (1.4104 material) chemical composition is listed in the following table based on cast analysis.
