What is 1.4062-CD?
1.4062-CD is 1.4062 supplied in the CD condition — pick when higher proof strength and better surface/tolerance are needed for machined or spring-type parts; ductility and formability drop sharply. 1.4062-CD has a yield strength of 750 MPa (109 ksi) and a tensile strength of 900 MPa (131 ksi) — stronger than 93% of stainless steel grades. Elongation at break is 18% and the elastic modulus is 200 GPa (29 Msi). 1.4062-CD has a density of 7.8 g/cm³ (0.282 lb/in³), heavier than 50% of stainless steel grades. It melts at 1,420°C (2,588 °F).

Working with 1.4062-CD
Is 1.4062 easy to machine?
Machines like 2205 but slightly easier: use rigid setups, sharp positive-rake carbide, ~25–35% lower cutting speed than 304, heavy feed to cut under the work-hardened layer, and copious coolant.
Can 1.4062 be welded?
Readily welded by GTAW/GMAW/SAW with 2209 or matching lean-duplex filler and Ar+~2%N2 backing; keep heat input ~0.5–2.5 kJ/mm and interpass below ~150 °C to hold the ferrite/austenite balance; no PWHT required.
Can 1.4062 be formed, bent or molded?
Cold forms well but needs roughly twice the press force of 304 and generous overbend for springback; hot form at 950–1200 °C followed by full solution anneal at 950–1050 °C with rapid water quench.
What surface finishes work on 1.4062?
Pickle and passivate after welding or hot work to remove heat tint; brushed, 2B and mirror-polished architectural finishes are all achievable; never anodize — electropolish for optimum corrosion performance.

What is 1.4062-CD used for?
1.4062-CD is typically used for structural panels, tanks, transport equipment and architectural elements. In short: molybdenum-free lean duplex; lower-cost 304 replacement; roughly twice 304 yield.
What is the yield strength of 1.4062-CD?
1.4062-CD has a typical yield strength of 750 MPa (109 ksi) and a tensile strength of 900 MPa (131 ksi) — stronger than 93% of stainless steel grades.
Is 1.4062-CD easy to machine?
Not especially — machinability is rated fair (35/100, better than 51% of stainless steel grades). Machines like 2205 but slightly easier: use rigid setups, sharp positive-rake carbide, ~25–35% lower cutting speed than 304, heavy feed to cut under the work-hardened layer, and copious coolant.
Can 1.4062-CD be welded?
Yes — weldability is rated very good (70/100). Readily welded by GTAW/GMAW/SAW with 2209 or matching lean-duplex filler and Ar+~2%N2 backing; keep heat input ~0.5–2.5 kJ/mm and interpass below ~150 °C to hold the ferrite/austenite balance; no PWHT required.
