13Cr Martensitic Stainless (var. 14)

metal

13Cr Martensitic Stainless Steel (variant 14) is a chromium-based martensitic stainless steel with elevated carbon content and molybdenum additions, designed to achieve high strength through heat treatment while maintaining corrosion resistance. This variant is used in applications demanding both hardness and moderate corrosion resistance, such as fasteners, valve components, and turbomachinery parts where strength-to-weight and fatigue performance are critical. The composition—particularly the carbon level (~0.78 wt%) and molybdenum alloying—positions this steel as an intermediate-strength martensitic grade suitable for aerospace, oil & gas, and power generation sectors where superior tensile properties and erosion/corrosion resistance outweigh the need for extreme toughness.

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
