Working with SUS836L-CD
Is SUS836L easy to machine?
Work-hardens rapidly — use rigid setups, positive-rake carbide, heavy feeds, low-to-moderate speed (~30–60 m/min) and flood coolant; never dwell in the cut.
Can SUS836L be welded?
GTAW/GMAW with over-alloyed Ni-base filler (ERNiCrMo-3 or -4) to compensate Mo segregation; low heat input, interpass < 100 °C, no preheat, no PWHT normally required.
Can SUS836L be formed, bent or molded?
Cold forms well but needs ~50 % higher press loads than 304; allow generous bend radii and intermediate solution anneal for severe draws.
What surface finishes work on SUS836L?
Pickle in HNO₃-HF and passivate after hot work or welding to restore the passive film; electropolishing gives best crevice-corrosion performance; not anodizable.

SUS836L-CD — frequently asked
What is SUS836L-CD used for?
SUS836L-CD is typically used for seawater systems, chemical process piping and flue gas desulfurization units. In short: high-Mo super-austenitic; chloride pitting resistant; low machinability, high cost.
What is the yield strength of SUS836L-CD?
SUS836L-CD has a typical yield strength of 520 MPa (75.4 ksi) and a tensile strength of 760 MPa (110 ksi) — stronger than 79% of stainless steel grades. Strength varies by condition: see the 6 listed tempers.
Is SUS836L-CD easy to machine?
Not especially — machinability is rated poor (30/100, worse than 70% of stainless steel grades). Work-hardens rapidly — use rigid setups, positive-rake carbide, heavy feeds, low-to-moderate speed (~30–60 m/min) and flood coolant; never dwell in the cut.
Can SUS836L-CD be welded?
Yes — weldability is rated very good (70/100). GTAW/GMAW with over-alloyed Ni-base filler (ERNiCrMo-3 or -4) to compensate Mo segregation; low heat input, interpass < 100 °C, no preheat, no PWHT normally required.
What surface finishes work on SUS836L-CD?
Pickle in HNO₃-HF and passivate after hot work or welding to restore the passive film; electropolishing gives best crevice-corrosion performance; not anodizable.
Can SUS836L-CD be formed, bent or molded?
Cold forms well but needs ~50 % higher press loads than 304; allow generous bend radii and intermediate solution anneal for severe draws.
What is the maximum service temperature of SUS836L-CD?
SUS836L-CD is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between SUS836L-SA and SUS836L-FH?
SA is the default condition — standard supply condition for plate, pipe and bar; maximum corrosion resistance and toughness. FH: maximum strength flat product for spring washers and shims; bending is essentially limited to flat-wise use. Yield strength is 320 MPa in SA versus 950 MPa in FH.
