Working with 1.4832
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.
1.4832 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

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 — frequently asked
What is 1.4832 used for?
1.4832 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?
1.4832 has a typical yield strength of 250 MPa (36.3 ksi) and a tensile strength of 500 MPa (72.5 ksi) — weaker than 91% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is 1.4832 easy to machine?
Not especially — machinability is rated poor (30/100, worse than 70% 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 be welded?
With care — weldability is rated fair (45/100). 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?
Sand-blast or pickle-and-passivate to remove casting scale; no anodizing — service oxide layer is the intended protective finish.
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 is the maximum service temperature of 1.4832?
1.4832 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.
How much does 1.4832 cost?
1.4832 is a premium-cost stainless steel ($$$), cheaper than about 51% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
