Working with 1.4832 Aged
Is 1.4832 easy to machine?
Machine with rigid setups, positive-rake carbide, low speed and heavy feed to cut under the work-hardened skin; expect ~35 % of 1212 rates and abrasive carbides.
Can 1.4832 be welded?
Weldable with matching 20/14 or over-alloyed 25/20 (ER310) / Ni-base filler; preheat 150–250 °C for heavy sections, limit heat input and stress-relieve or solution anneal after repair.
Can 1.4832 be formed, bent or molded?
Sand, shell or centrifugal cast only; good fluidity thanks to Si, but design generous fillets and feeders because of high solidification shrinkage.
What surface finishes work on 1.4832?
Sand-blast or pickle-and-passivate to remove casting scale; no anodizing — service oxide layer is the intended protective finish.

1.4832 Aged — frequently asked
What is 1.4832 Aged used for?
1.4832 Aged is typically used for heat-treatment baskets and trays, furnace conveyor parts, annealing box components, radiant tube supports and high-temperature process equipment castings. In short: more ductile than 1.4826; 1000 °C scaling resistance; cast-only heat-resistant grade.
What is the yield strength of 1.4832 Aged?
1.4832 Aged has a typical yield strength of 300 MPa (43.5 ksi) and a tensile strength of 520 MPa (75.4 ksi) — weaker than 68% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is 1.4832 Aged easy to machine?
Not especially — machinability is rated poor (24/100, worse than 93% of stainless steel grades). Machine with rigid setups, positive-rake carbide, low speed and heavy feed to cut under the work-hardened skin; expect ~35 % of 1212 rates and abrasive carbides.
Can 1.4832 Aged be welded?
Not readily — weldability is rated poor (20/100). Weldable with matching 20/14 or over-alloyed 25/20 (ER310) / Ni-base filler; preheat 150–250 °C for heavy sections, limit heat input and stress-relieve or solution anneal after repair.
What surface finishes work on 1.4832 Aged?
Sand-blast or pickle-and-passivate to remove casting scale; no anodizing — service oxide layer is the intended protective finish.
Can 1.4832 Aged be formed, bent or molded?
Sand, shell or centrifugal cast only; good fluidity thanks to Si, but design generous fillets and feeders because of high solidification shrinkage.
What is the maximum service temperature of 1.4832 Aged?
1.4832 Aged is rated for continuous use to about 1,000°C (1,832 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4832-AC and 1.4832 Aged?
AC is the default condition — standard supply condition for furnace parts and trays; adequate strength and oxidation resistance without extra heat treatment. Aged: reference condition for assessing used furnace parts: carbide/σ precipitation raises hardness and strongly reduces room-temperature ductility and impact energy. Yield strength is 250 MPa in AC versus 300 MPa in Aged.
