Working with 08Cr17Ti Annealed
Is 08Cr17Ti easy to machine?
Machines like 430 but gummier: sharp tools, rigid setup, positive rake, 20–25% lower speed than carbon steel, generous coolant to avoid built-up edge.
Can 08Cr17Ti be welded?
Excellent weldability for a ferritic — Ti stabilization avoids sensitization; use low heat input, 409/430Ti or austenitic 309L filler, no preheat for thin gauge, avoid grain coarsening above ~950 °C.
Can 08Cr17Ti be formed, bent or molded?
Good deep drawing and roll forming with r-value near 1.4; watch for ridging/roping on drawn panels and use larger bend radii than for 304.
What surface finishes work on 08Cr17Ti?
Not anodizable; passivate per ASTM A967, or apply BA/No.4 mechanical finishes, electropolishing or PVD color coatings; keep free of carbon-steel contamination to prevent rust staining.

08Cr17Ti Annealed — frequently asked
What is 08Cr17Ti Annealed used for?
08Cr17Ti Annealed is typically used for automotive trim and exhaust, household appliances, architectural panels and food processing equipment. In short: ti-stabilized 439 equivalent; low-nickel 304 substitute; best-welding ferritic sheet.
What is the yield strength of 08Cr17Ti Annealed?
08Cr17Ti Annealed has a typical yield strength of 300 MPa (43.5 ksi) and a tensile strength of 480 MPa (69.6 ksi) — weaker than 68% of stainless steel grades. Strength varies by condition: see the 5 listed tempers.
Is 08Cr17Ti Annealed easy to machine?
Reasonably — machinability is rated fair (50/100, better than 90% of stainless steel grades). Machines like 430 but gummier: sharp tools, rigid setup, positive rake, 20–25% lower speed than carbon steel, generous coolant to avoid built-up edge.
Can 08Cr17Ti Annealed be welded?
Yes — weldability is rated very good (80/100). Excellent weldability for a ferritic — Ti stabilization avoids sensitization; use low heat input, 409/430Ti or austenitic 309L filler, no preheat for thin gauge, avoid grain coarsening above ~950 °C.
What surface finishes work on 08Cr17Ti Annealed?
Not anodizable; passivate per ASTM A967, or apply BA/No.4 mechanical finishes, electropolishing or PVD color coatings; keep free of carbon-steel contamination to prevent rust staining.
Can 08Cr17Ti Annealed be formed, bent or molded?
Good deep drawing and roll forming with r-value near 1.4; watch for ridging/roping on drawn panels and use larger bend radii than for 304.
What is the maximum service temperature of 08Cr17Ti Annealed?
08Cr17Ti Annealed is rated for continuous use to about 815°C (1,499 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 08Cr17Ti Annealed and 08Cr17Ti-CD?
Annealed is the default condition — standard stocked condition for sheet, coil and plate: maximum ductility for deep drawing and forming. CD: standard bar and wire condition for machined fittings, fasteners and welded wire assemblies. Yield strength is 300 MPa in Annealed versus 430 MPa in CD.
