Working with 1.4982-CD
Is 1.4982 easy to machine?
Machines like a tough 316 but harder: rigid setups, positive-rake sharp carbide, heavy constant feed and flood coolant to avoid work-hardened glazing; expect ~30 % of 1212 rates.
Can 1.4982 be welded?
Readily welded by TIG/MMA/SAW with matching Nb-bearing 15Cr-10Ni-6Mn filler; keep heat input and interpass temperature low to limit hot-cracking, no post-weld heat treatment mandatory but 750 °C stabilizing is common for creep duty.
Can 1.4982 be formed, bent or molded?
Hot work 1150–950 °C then solution treat; cold forming possible but the high work-hardening rate demands high forming loads and intermediate anneals.
What surface finishes work on 1.4982?
Pickle and passivate after hot work or welding to restore the chromium oxide film; electropolishing gives good surface for steam service; no anodizing (ferrous).

1.4982-CD — frequently asked
What is 1.4982-CD used for?
1.4982-CD is typically used for high-temperature bolts, turbine casings and boiler support components. In short: most weldable creep austenitic; nb/V/B microalloyed; 700 °C bolting steel.
What is the yield strength of 1.4982-CD?
1.4982-CD has a typical yield strength of 600 MPa (87 ksi) and a tensile strength of 800 MPa (116 ksi) — stronger than 86% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is 1.4982-CD easy to machine?
Not especially — machinability is rated fair (35/100, better than 51% of stainless steel grades). Machines like a tough 316 but harder: rigid setups, positive-rake sharp carbide, heavy constant feed and flood coolant to avoid work-hardened glazing; expect ~30 % of 1212 rates.
Can 1.4982-CD be welded?
Yes — weldability is rated very good (70/100). Readily welded by TIG/MMA/SAW with matching Nb-bearing 15Cr-10Ni-6Mn filler; keep heat input and interpass temperature low to limit hot-cracking, no post-weld heat treatment mandatory but 750 °C stabilizing is common for creep duty.
What surface finishes work on 1.4982-CD?
Pickle and passivate after hot work or welding to restore the chromium oxide film; electropolishing gives good surface for steam service; no anodizing (ferrous).
Can 1.4982-CD be formed, bent or molded?
Hot work 1150–950 °C then solution treat; cold forming possible but the high work-hardening rate demands high forming loads and intermediate anneals.
What is the maximum service temperature of 1.4982-CD?
1.4982-CD is rated for continuous use to about 600°C (1,112 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4982-ST and 1.4982-CD?
ST is the default condition — standard supply condition for tube, pipe and bar; best ductility and creep ductility, baseline for all service exposure. CD: bright cold-drawn bar for machined fasteners and studs where higher room-temperature proof stress and better surface/tolerance are needed. Yield strength is 330 MPa in ST versus 600 MPa in CD.
