Working with 1.4832-SA
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-SA — frequently asked
What is 1.4832-SA used for?
1.4832-SA 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-SA?
1.4832-SA has a typical yield strength of 235 MPa (34.1 ksi) and a tensile strength of 480 MPa (69.6 ksi) — weaker than 98% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is 1.4832-SA easy to machine?
Not especially — machinability is rated fair (35/100, better than 51% 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-SA be welded?
With care — weldability is rated fair (50/100). 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-SA?
Sand-blast or pickle-and-passivate to remove casting scale; no anodizing — service oxide layer is the intended protective finish.
Can 1.4832-SA 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-SA?
1.4832-SA 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.
