Working with 1.4615-FH
Is 1.4615 easy to machine?
Gummy and strongly work-hardening — use rigid setups, positive-rake carbide, heavy feeds, low-to-moderate speed and flood coolant; expect ~40 % of 1212 free-cutting rate.
Can 1.4615 be welded?
Weldable by GTAW/GMAW/resistance welding with 308L/307 (Cr-Mn) type filler, no preheat, low heat input and no post-weld heat treatment; higher N and Cu raise hot-crack and heat-tint sensitivity, so pickle or passivate welds.
Can 1.4615 be formed, bent or molded?
Excellent deep-drawing and stamping behaviour thanks to Cu; springback and press loads are higher than 304, and heavy cold work induces magnetic deformation martensite — interstage annealing helps on severe draws.
What surface finishes work on 1.4615?
Takes BA, No.4 brushed and mirror-polished finishes and PVD coating well; not anodisable — passivate after machining/welding and avoid chloride-containing cleaners to prevent pitting.

1.4615-FH — frequently asked
What is 1.4615-FH used for?
1.4615-FH is typically used for decorative trim, appliance parts and low-load structural components. In short: cost-reduced 304 substitute; deep-draw 200-series grade; low-nickel decorative stainless.
What is the yield strength of 1.4615-FH?
1.4615-FH has a typical yield strength of 1,050 MPa (152 ksi) and a tensile strength of 1,320 MPa (191 ksi) — stronger than 98% of stainless steel grades. Strength varies by condition: see the 7 listed tempers.
Is 1.4615-FH easy to machine?
Not especially — machinability is rated poor (28/100, worse than 79% of stainless steel grades). Gummy and strongly work-hardening — use rigid setups, positive-rake carbide, heavy feeds, low-to-moderate speed and flood coolant; expect ~40 % of 1212 free-cutting rate.
Can 1.4615-FH be welded?
With care — weldability is rated fair (45/100). Weldable by GTAW/GMAW/resistance welding with 308L/307 (Cr-Mn) type filler, no preheat, low heat input and no post-weld heat treatment; higher N and Cu raise hot-crack and heat-tint sensitivity, so pickle or passivate welds.
What surface finishes work on 1.4615-FH?
Takes BA, No.4 brushed and mirror-polished finishes and PVD coating well; not anodisable — passivate after machining/welding and avoid chloride-containing cleaners to prevent pitting.
Can 1.4615-FH be formed, bent or molded?
Excellent deep-drawing and stamping behaviour thanks to Cu; springback and press loads are higher than 304, and heavy cold work induces magnetic deformation martensite — interstage annealing helps on severe draws.
What is the maximum service temperature of 1.4615-FH?
1.4615-FH is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4615 Annealed and 1.4615 Spring?
Annealed is the default condition — standard stocked condition for deep drawing, stamping, tube making and decorative sheet. Spring: heavily drawn wire for low-cost springs, filters and mesh in dry indoor service. Yield strength is 330 MPa in Annealed versus 1,350 MPa in Spring.
