| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
STDefault Solution annealed | Standard supply condition for tube, pipe and bar; best ductility and creep ductility, baseline for all service exposure. | 330 | 660 | 45 | 185 HB | — |
Solution annealed + stabilizing/stress-relief ~750 °C | Choose for welded superheater assemblies and creep service where NbC/VC precipitation and residual-stress removal before start-up are wanted. | 370 | 700 | 38 | 200 HB | 2 % IACS |
Warm worked (≈15–25 % reduction) bolting condition | Standard high-temperature bolting condition per DIN 17240: warm/cold deformation after solution treatment raises proof stress and relaxation resistance at 550–650 °C. | 560 | 780 | 25 | 22 HRC | 2 % IACS |

What is 1.4982?
1.4982 (X10CrNiMoMnNbVB15-10-1) is a Nb/V/B-microalloyed, manganese-bearing austenitic steel engineered for creep strength and dimensional stability in high-temperature turbine and boiler bolting up to about 700 °C. Supplied solution treated, solution treated plus stress relieved, cold drawn or as welded product, it gives 330 MPa yield, 660 MPa tensile, 45 % elongation and 185 HB (90 HRB). Weldability is the highest of the creep-resistant austenitics listed here at 70/100, but machinability is low at 30/100 and the high work-hardening rate raises forming loads. 1.4981 is the nearest alternative when Nb stabilization alone is enough. 1.4982 has a density of 7.9 g/cm³ (0.285 lb/in³), heavier than 68% of stainless steel grades. It melts at 1,370°C (2,498 °F). 1.4982 has a yield strength of 330 MPa (47.9 ksi) and a tensile strength of 660 MPa (95.7 ksi) — weaker than 57% of stainless steel grades. Elongation at break is 45% and the elastic modulus is 200 GPa (29 Msi).

Working with 1.4982
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.

1.4982 — frequently asked
What is 1.4982 used for?
1.4982 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?
1.4982 has a typical yield strength of 330 MPa (47.9 ksi) and a tensile strength of 660 MPa (95.7 ksi) — weaker than 57% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is 1.4982 easy to machine?
Not especially — machinability is rated poor (30/100, worse than 70% 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 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.

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 is the maximum service temperature of 1.4982?
1.4982 is rated for continuous use to about 700°C (1,292 °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.
