What is 1.4962?
1.4962 (X12CrNiWTiB16-13) is a tungsten-, titanium- and boron-alloyed austenitic heat-resistant steel developed for creep strength in fossil-fired power plant components, supplied solution annealed (+AT) or cold-worked (+WW). It is chosen for elevated-temperature strength to about 700 °C — 320 MPa yield, 700 MPa tensile, 38 % elongation, 185 HB (89 HRB) — mostly as seamless tube, headers and bar for bolting. Boron raises hot-cracking risk (weldability 55/100) and TiC and borides wear tool edges (machinability 33/100); corrosion resistance is moderate at 62/100. Where creep strength is not the driver, 321 or 316Ti is easier to buy and fabricate. 1.4962 has a density of 7.9 g/cm³ (0.285 lb/in³), heavier than 68% of stainless steel grades. It melts at 1,400°C (2,552 °F). 1.4962 has a yield strength of 320 MPa (46.4 ksi) and a tensile strength of 700 MPa (102 ksi) — weaker than 60% of stainless steel grades. Elongation at break is 38% and the elastic modulus is 200 GPa (29 Msi).
What is 1.4962 used for?
- superheater tubing
- boiler headers
- high-temperature bolting
- steam turbine components
Limitations
- Low electrical conductivity — 2 % IACS, worse than 77% of stainless steel grades

Working with 1.4962
Is 1.4962 easy to machine?
Gummy and strongly work-hardening — use rigid setups, sharp carbide (coated) tools, low speed/high feed, generous flood coolant and avoid dwelling; TiC and borides accelerate edge wear.
Can 1.4962 be welded?
Weldable by TIG/MIG/SMAW with matched or 16-8-2 / Ni-base filler, but boron raises hot-cracking risk: minimise heat input and restraint, no preheat, interpass < 150 °C, and solution anneal where design permits.
Can 1.4962 be formed, bent or molded?
Hot working 1150–900 °C followed by solution anneal at 1050–1100 °C with rapid cooling; cold forming needs ~40–50 % more force than 304 and intermediate anneals for severe draws.

1.4962 — frequently asked
What is 1.4962 used for?
1.4962 is typically used for superheater tubing, boiler headers, high-temperature bolting and steam turbine components. In short: tungsten-boron creep grade; 700 °C service limit; tube and bolting alloy.
What is the yield strength of 1.4962?
1.4962 has a typical yield strength of 320 MPa (46.4 ksi) and a tensile strength of 700 MPa (102 ksi) — weaker than 60% of stainless steel grades. Strength varies by condition: see the 2 listed tempers.
Is 1.4962 easy to machine?
Not especially — machinability is rated poor (33/100, worse than 57% of stainless steel grades). Gummy and strongly work-hardening — use rigid setups, sharp carbide (coated) tools, low speed/high feed, generous flood coolant and avoid dwelling; TiC and borides accelerate edge wear.
