Working with 1.4516 Annealed-2B
Is 1.4516 easy to machine?
Machines more freely than 304 (short-ish chips, lower work hardening); use sharp positive-rake carbide, 60–120 m/min, generous coolant to avoid built-up edge.
Can 1.4516 be welded?
Readily welded by TIG/MIG/laser/resistance without post-weld anneal thanks to Ti stabilization; limit heat input and use 309L or matching Ti-stabilized filler, avoid excessive grain growth in thick sections.
Can 1.4516 be formed, bent or molded?
Good roll-forming, bending and moderate deep drawing; lower n-value than austenitics so allow larger bend radii (≥1t) and watch for ridging/roping in draw direction.
What surface finishes work on 1.4516?
Not anodizable — pickle and passivate after welding, or apply aluminized/organic coatings for cosmetic or long-term wet exposure; electropolishing gives a modest brightness improvement.

1.4516 Annealed-2B — frequently asked
What is 1.4516 Annealed-2B used for?
1.4516 Annealed-2B is typically used for exhaust systems, heat shields and low-stress structural trim. In short: low-cost 12Cr ferritic; weldable without post-anneal; exhaust and heat-shield grade.
What is the yield strength of 1.4516 Annealed-2B?
1.4516 Annealed-2B has a typical yield strength of 320 MPa (46.4 ksi) and a tensile strength of 490 MPa (71.1 ksi) — weaker than 60% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.
Is 1.4516 Annealed-2B easy to machine?
Reasonably — machinability is rated good (55/100, better than 94% of stainless steel grades). Machines more freely than 304 (short-ish chips, lower work hardening); use sharp positive-rake carbide, 60–120 m/min, generous coolant to avoid built-up edge.
Can 1.4516 Annealed-2B be welded?
Yes — weldability is rated very good (78/100). Readily welded by TIG/MIG/laser/resistance without post-weld anneal thanks to Ti stabilization; limit heat input and use 309L or matching Ti-stabilized filler, avoid excessive grain growth in thick sections.
What surface finishes work on 1.4516 Annealed-2B?
Not anodizable — pickle and passivate after welding, or apply aluminized/organic coatings for cosmetic or long-term wet exposure; electropolishing gives a modest brightness improvement.
Can 1.4516 Annealed-2B be formed, bent or molded?
Good roll-forming, bending and moderate deep drawing; lower n-value than austenitics so allow larger bend radii (≥1t) and watch for ridging/roping in draw direction.
What is the maximum service temperature of 1.4516 Annealed-2B?
1.4516 Annealed-2B is rated for continuous use to about 650°C (1,202 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4516 Annealed-2B and 1.4516-CD?
Annealed-2B is the default condition — standard stocked condition for exhaust and formed parts — best combination of formability and weldability. CD: bar stock with raised strength and tight tolerance for machined fittings and shafts in mild service. Yield strength is 320 MPa in Annealed-2B versus 480 MPa in CD.
